Figure 2. ADSP-21061 System
Data Register FileA general purpose data register file is used for transferring databetween the computation units and the data buses, and for stor-ing intermediate results. This 10-port, 32-register (16 primary,16 secondary) register file, combined with the ADSP-21000Harvard architecture, allows unconstrained data flow betweencomputation units and internal memory.
Single-Cycle Fetch of Instruction and Two OperandsThe ADSP-21061 features an enhanced Harvard architecture inwhich the data memory (DM) bus transfers data and the pro-gram memory (PM) bus transfers both instructions and data(see Figure 1). With its separate program and data memorybuses and on-chip instruction cache, the processor can simulta-neously fetch two operands and an instruction (from the cache),all in a single cycle.
Instruction CacheThe ADSP-21061 includes an on-chip instruction cache thatenables three-bus operation for fetching an instruction and twodata values. The cache is selective—only the instructions whosefetches conflict with PM bus data accesses are cached. Thisallows full-speed execution of core, looped operations such asdigital filter multiply-accumulates and FFT butterfly processing.
Data Address Generators with Hardware Circular BuffersThe ADSP-21061’s two data address generators (DAGs) imple-ment circular data buffers in hardware. Circular buffers allowefficient programming of delay lines and other data structuresrequired in digital signal processing, and are commonly used indigital filters and Fourier transforms. The ADSP-21061’s twoDAGs contain sufficient registers to allow the creation of up to32 circular buffers (16 primary register sets, 16 secondary). TheDAGs automatically handle address pointer wraparound, reduc-ing overhead, increasing performance and simplifying imple-mentation. Circular buffers can start and end at any memorylocation.
Flexible Instruction SetThe 48-bit instruction word accommodates a variety of paralleloperations, for concise programming. For example, the ADSP-21061 can conditionally execute a multiply, an add, a subtractand a branch, all in a single instruction.
ADSP-21061 FEATURESAugmenting the ADSP-21000 family core, the ADSP-21061adds the following architectural features:
Dual-Ported On-Chip MemoryThe ADSP-21061 contains 1 megabit of on-chip SRAM, orga-nized as two banks of 0.5 Mbits each. Each bank has eight 16-bit columns with 4K 16-bit words per column. Each memoryblock is dual-ported for single-cycle, independent accesses bythe core processor and I/O processor or DMA controller. Thedual-ported memory and separate on-chip buses allow two datatransfers from the core and one from I/O, all in a single cycle.
On the ADSP-21061, the memory can be configured as a maxi-mum of 32K words of 32-bit data, 64K words for 16-bit data,16K words of 48-bit instructions (and 40-bit data) or combina-tions of different word sizes up to 1 megabit. All the memorycan be accessed as 16-bit, 32-bit or 48-bit.
A 16-bit floating-point storage format is supported that effec-tively doubles the amount of data that may be stored on chip.Conversion between the 32-bit floating-point and 16-bit floating-point formats is done in a single instruction.
While each memory block can store combinations of code anddata, accesses are most efficient when one block stores data, us-ing the DM bus for transfers, and the other block stores instruc-tions and data, using the PM bus for transfers. Using the DMand PM buses in this way, with one dedicated to each memoryblock, assures single-cycle execution with two data transfers. Inthis case, the instruction must be available in the cache. Single-cycle execution is also maintained when one of the data oper-ands is transferred to or from off-chip, via the ADSP-21061’sexternal port.
ADSP-21061

Off-Chip Memory and Peripherals InterfaceThe ADSP-21061’s external port provides the processor’s inter-face to off-chip memory and peripherals. The 4-gigaword off-chip address space is included in the ADSP-21061’s unifiedaddress space. The separate on-chip buses—for programmemory, data memory and I/O—are multiplexed at the externalport to create an external system bus with a single 32-bit addressbus and a single 48-bit (or 32-bit) data bus. The on-chipSuper Harvard Architecture provides three-bus performance,while the off-chip unified address space gives flexibility to thedesigner.
Addressing of external memory devices is facilitated by on-chipdecoding of high order address lines to generate memory bankselect signals. Separate control lines are also generated for sim-plified addressing of page-mode DRAM. The ADSP-21061provides programmable memory wait states and external memoryacknowledge controls to allow interfacing to DRAM and peripher-als with variable access, hold and disable time requirements.
Host Processor InterfaceThe ADSP-21061’s host interface allows easy connection tostandard microprocessor buses, both 16-bit and 32-bit, withlittle additional hardware required. Asynchronous transfers atspeeds up to the full clock rate of the processor are supported.The host interface is accessed through the ADSP-21061’s exter-nal port and is memory-mapped into the unified address space.Two channels of DMA are available for the host interface; codeand data transfers are accomplished with low software overhead.
The host processor requests the ADSP-21061’s external buswith the host bus request (HBR), host bus grant (HBG) andready (REDY) signals. The host can directly read and write theinternal memory of the ADSP-21061, and can access the DMAchannel setup and mailbox registers. Vector interrupt support isprovided for efficient execution of host commands.
DMA ControllerThe ADSP-21061’s on-chip DMA controller allows zero-over-head, non-intrusive data transfers without processor interven-tion. The DMA controller operates independently and invisiblyto the processor core, allowing DMA operations to occur whilethe core is simultaneously executing its program instructions.
DMA transfers can occur between the ADSP-21061’s internalmemory and either external memory, external peripherals, or ahost processor. DMA transfers can also occur between theADSP-21061’s internal memory and its serial ports. DMAtransfers between external memory and external peripheraldevices are another option. External bus packing to 16-, 32-or 48-bit words is performed during DMA transfers.
Six channels of DMA are available on the ADSP-21061—fourvia the serial ports, and two via the processor’s external port (foreither host processor, other ADSP-21061s, memory or I/Otransfers). Programs can be downloaded to the ADSP-21061using DMA transfers. Asynchronous off-chip peripherals cancontrol two DMA channels using DMA Request/Grant lines(DMAR1–2, DMAG1–2). Other DMA features include interruptgeneration upon completion of DMA transfers and DMA chain-ing for automatic linked DMA transfers.
Serial PortsThe ADSP-21061 features two synchronous serial ports thatprovide an inexpensive interface to a wide variety of digital andmixed-signal peripheral devices. The serial ports can operate atthe full clock rate of the processor, providing each with a maxi-mum data rate of 40 Mbit/s. Independent transmit and receivefunctions provide greater flexibility for serial communications.Serial port data can be automatically transferred to and fromon-chip memory via DMA. Each of the serial ports offers TDMmultichannel mode.
The serial ports can operate with little-endian or big-endiantransmission formats, with word lengths selectable from threebits to 32 bits. They offer selectable synchronization and trans-mit modes as well as optional µ-law or A-law companding.Serial port clocks and frame syncs can be internally or externallygenerated. The serial ports also include keyword and keymaskfeatures to enhance interprocessor communication.
MultiprocessingThe ADSP-21061 offers powerful features tailored to multipro-cessing DSP systems. The unified address space allows directinterprocessor accesses of each ADSP-21061’s internal memory.Distributed bus arbitration logic is included on-chip for simple,glueless connection of systems containing up to six ADSP-21061sand a host processor. Master processor changeover incurs onlyone cycle of overhead. Bus arbitration is selectable as eitherfixed or rotating priority. Bus lock allows indivisible read-modify-write sequences for semaphores. A vector interrupt is providedfor interprocessor commands. Maximum throughput for inter-processor data transfer is 240 Mbytes/sec over the external port.Broadcast writes allow simultaneous transmission of data toall ADSP-21061s and can be used to implement reflectivesemaphores.
Program BootingThe internal memory of the ADSP-21061 can be booted at sys-tem power-up from either an 8-bit EPROM or a host processor.Selection of the boot source is controlled by the BMS (BootMemory Select), EBOOT (EPROM Boot), and LBOOT (HostBoot) pins. 32-bit and 16-bit host processors can be used forbooting. See the BMS pin in the Pin Descriptions section of thisdata sheet.

On the ADSP-21061, Block 0 starts at the beginning of internalmemory, normal word address 0x0002 0000. Block 1 starts atthe end of Block 0, with contiguous addresses. The remainingaddresses in internal memory are divided into blocks that aliasinto Block 1. This allows any code or data stored in Block 1 onthe ADSP-21062 to retain the same addresses on the ADSP-21061—these addresses will alias into the actual Block 1 of eachprocessor.
If you develop your application using the ADSP-21062, but willmigrate to the ADSP-21061, use only the first eight columns ofeach memory bank. Limit your application to 8K of instructionsor up to 16K of data in each bank of the ADSP-21062, or anycombinations of instructions or data that does not exceed thememory bank.
DEVELOPMENT TOOLSThe ADSP-21061 is supported with a complete set of softwareand hardware development tools, including an EZ-ICE® In-Cir-cuit Emulator, EZ-Kit Lite, and development software. TheSHARC® EZ-Kit Lite* is a complete low cost package for DSPevaluation and prototyping. The EZ-Kit Lite contains an evalu-ation board with an ADSP-21061 (5 V) processor and providesa serial connection to your PC. The EZ-Kit Lite also includesan optimizing compiler, assembler, instruction level simulator,run-time libraries, diagnostic utilities and a complete set of ex-ample programs.
The same EZ-ICE hardware can be used for the ADSP-21060/ADSP-21062, to fully emulate the ADSP-21061, with the excep-tion of displaying and modifying the two new SPORTS regis-ters. The emulator will not display these two registers, butyour code can use them.

PIN DESCRIPTIONSADSP-21061 pin definitions are listed below. Inputs identifiedas synchronous (S) must meet timing requirements with respectto CLKIN (or with respect to TCK for TMS, TDI). Inputsidentified as asynchronous (A) can be asserted asynchronouslyto CLKIN (or to TCK for TRST).
Unused inputs should be tied or pulled to IVDD or IGND,except for ADDR31-0, DATA47-0, FLAG3-0, SW and inputs thathave internal pull-up or pull-down resistors (CPA, ACK, DTx,
DRx, TCLKx, RCLKx, TMS and TDI)—these pins can be leftfloating. These pins have a logic-level hold circuit that preventsthe input from floating internally.
I = Input S = Synchronous P = Power Supply(O/D) = Open Drain O = Output A = AsynchronousG = Ground (A/D) = Active DriveT = Three-State (when SBTS is asserted, or when theADSP-2106x is a bus slave)
PIN FUNCTION DESCRIPTIONS
Pin Type Function
ADDR31-0 I/O/T External Bus Address. The ADSP-21061 outputs addresses for external memory and peripheralson these pins. In a multiprocessor system the bus master outputs addresses for read/writes of the in-ternal memory or IOP registers of other ADSP-2106xs. The ADSP-21061 inputs addresses when a hostprocessor or multiprocessing bus master is reading or writing its internal memory or IOP registers.
DATA47-0 I/O/T External Bus Data. The ADSP-21061 inputs and outputs data and instructions on these pins.The external data bus transfers 32-bit single-precision floating-point data and 32-bit fixed-pointdata over Bits 47-16. 40-bit extended-precision floating-point data is transferred over Bits 47-8 ofthe bus. 16-bit short word data is transferred over Bits 31-16 of the bus. Pull-up resistors on un-used DATA pins are not necessary.
MS3-0 O/T Memory Select Lines. These lines are asserted (low) as chip selects for the corresponding banksof external memory. Memory bank size must be defined in the ADSP-21061’s system control regis-ter (SYSCON). The MS3-0 lines are decoded memory address lines that change at the same time asthe other address lines. When no external memory access is occurring the MS3-0 lines are inactive;they are active, however, when a conditional memory access instruction is executed, whether or notthe condition is true. MS0 can be used with the PAGE signal to implement a bank of DRAMmemory (Bank 0). In a multiprocessor system the MS3-0 lines are output by the bus master.
RD I/O/T Memory Read Strobe. This pin is asserted (low) when the ADSP-21061 reads from externalmemory devices or from the internal memory of other ADSP-21061s. External devices (includingother ADSP-21061s) must assert RD to read from the ADSP-21061’s internal memory. In a multi-processor system RD is output by the bus master and is input by all other ADSP-21061s.
WR I/O/T Memory Write Strobe. This pin is asserted (low) when the ADSP-21061 writes to externalmemory devices or to the internal memory of other ADSP-21061s. External devices must assertWR to write to the ADSP-21061’s internal memory. In a multiprocessor system WR is output bythe bus master and is input by all other ADSP-21061s.
PAGE O/T DRAM Page Boundary. The ADSP-21061 asserts this pin to signal that an external DRAM pageboundary has been crossed. DRAM page size must be defined in the ADSP-21061’s memory con-trol register (WAIT). DRAM can only be implemented in external memory Bank 0; the PAGE sig-nal can only be activated for Bank 0 accesses. In a multiprocessor system PAGE is output by thebus master.
ADRCLK O/T Address Clock for synchronous external memories. Addresses on ADDR31-0 are valid before therising edge of ADRCLK. In a multiprocessing system ADRCLK is output by the bus master.
SW I/O/T Synchronous Write Select. This signal is used to interface the ADSP-2106x to synchronousmemory devices (including other ADSP-21061s). The ADSP-21061 asserts SW (low) to providean early indication of an impending write cycle, which can be aborted if WR is not later asserted(e.g. in a conditional write instruction). In a multiprocessor system, SW is output by the bus masterand is input by all other ADSP-21061s to determine if the multiprocessor memory access is a reador write. SW is asserted at the same time as the address output. A host processor using synchronouswrites must assert this pin when writing to the ADSP-21061(s).
ACK I/O/S Memory Acknowledge. External devices can deassert ACK (low) to add wait states to an externalmemory access. ACK is used by I/O devices, memory controllers or other peripherals to hold offcompletion of an external memory access. The ADSP-21061 deasserts ACK as an output to addwait states to a synchronous access of its internal memory. In a multiprocessor system, a slaveADSP-21061 deasserts the bus master’s ACK input to add wait state(s) to an access of its internalmemory. The bus master has a keeper latch on its ACK pin that maintains the input at the level itwas last driven to.

Pin Type Function
SBTS I/S Suspend Bus Three-State. External devices can assert SBTS (low) to place the external bus address,data, selects, and strobes in a high impedance state for the following cycle. If the ADSP-21061attempts to access external memory while SBTS is asserted, the processor will halt and the memoryaccess will not be completed until SBTS is deasserted. SBTS should only be used to recover fromPAGE faults or host processor/ADSP-21061 deadlock.
IRQ2-0 I/A Interrupt Request Lines. May be either edge-triggered or level-sensitive.
FLAG3-0 I/O/A Flag Pins. Each is configured via control bits as either an input or an output. As an input, it can betested as a condition. As an output, it can be used to signal external peripherals.
TIMEXP O Timer Expired. Asserted for four cycles when the timer is enabled and TCOUNT decrements tozero.
HBR I/A Host Bus Request. Must be asserted by a host processor to request control of the ADSP-21061’sexternal bus. When HBR is asserted in a multiprocessing system, the ADSP-21061 that is bus masterwill relinquish the bus and assert HBG. To relinquish the bus, the ADSP-21061 places the address,data, select, and strobe lines in a high impedance state. HBR has priority over all ADSP-21061 busrequests (BR6-1) in a multiprocessing system.
HBG I/O Host Bus Grant. Acknowledges an HBR bus request, indicating that the host processor may takecontrol of the external bus. HBG is asserted (held low) by the ADSP-21061 until HBR is released. In amultiprocessing system, HBG is output by the ADSP-21061 bus master and is monitored by all others.
CS I/A Chip Select. Asserted by host processor to select the ADSP-21061.
REDY (O/D) O Host Bus Acknowledge. The ADSP-2106x deasserts REDY (low) to add wait states to an asynchro-nous access of its internal memory or IOP registers by a host. Open drain output (O/D) by default; canbe programmed in ADREDY bit of SYSCON register to be active drive (A/D). REDY will only beoutput if the CS and HBR inputs are asserted.
DMAR1 I/A DMA Request 1 (DMA Channel 7).
DMAR2 I/A DMA Request 2 (DMA Channel 6).
DMAG1 O/T DMA Grant 1 (DMA Channel 7).
DMAG2 O/T DMA Grant 2 (DMA Channel 6).
BR6-1 I/O/S Multiprocessing Bus Requests. Used by multiprocessing ADSP-21061s to arbitrate for bus master-ship. An ADSP-21061 only drives its own BRx line (corresponding to the value of its ID2-0 inputs) andmonitors all others. In a multiprocessor system with less than six ADSP-21061s, the unused BRx pinsshould be tied high; the processor’s own BRx line must not be tied high or low because it is an output.
ID2-0 I Multiprocessing ID. Determines which multiprocessing bus request (BR1–BR6) is used by ADSP-21061. ID = 001 corresponds to BR1, ID = 010 corresponds to BR2, etc. ID = 000 in single-processor sys-tems. These lines are a system configuration selection which should be hardwired or only changed at reset.
RPBA I/S Rotating Priority Bus Arbitration Select. When RPBA is high, rotating priority for multiprocessorbus arbitration is selected. When RPBA is low, fixed priority is selected. This signal is a system con-figuration selection which must be set to the same value on every ADSP-21061. If the value of RPBA ischanged during system operation, it must be changed in the same CLKIN cycle on every ADSP-21061.
CPA (O/D) I/O Core Priority Access. Asserting its CPA pin allows the core processor of an ADSP-21061 bus slaveto interrupt background DMA transfers and gain access to the external bus. CPA is an open drain out-put that is connected to all ADSP-2106xs in the system. The CPA pin has an internal 5 kΩ pull-upresistor. If core access priority is not required in a system, the CPA pin should be left unconnected.
DTx O Data Transmit (Serial Ports 0, 1). Each DT pin has a 50 kΩ internal pull-up resistor.
DRx I Data Receive (Serial Ports 0, 1). Each DR pin has a 50 kΩ internal pull-up resistor.
TCLKx I/O Transmit Clock (Serial Ports 0, 1). Each TCLK pin has a 50 kΩ internal pull-up resistor.
RCLKx I/O Receive Clock (Serial Ports 0, 1). Each RCLK pin has a 50 kΩ internal pull-up resistor.

RFSx I/O Receive Frame Sync (Serial Ports 0, 1).
EBOOT I EPROM Boot Select. When EBOOT is high, the ADSP-21061 is configured for booting from an 8-bit EPROM. When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See tablebelow. This signal is a system configuration selection which should be hardwired.
LBOOT I Link Boot—Must be tied to GND.
BMS I/O/T* Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOT = 1,LBOOT = 0). In a multiprocessor system, BMS is output by the bus master. Input: When low, indi-cates that no booting will occur and that ADSP-21061 will begin executing instructions from externalmemory. See table below. This input is a system configuration selection which should be hardwired.

CLKIN I Clock In. External clock input to the ADSP-21061. The instruction cycle rate is equal to CLKIN.CLKIN may not be halted, changed, or operated below the specified frequency.
RESET I/A Processor Reset. Resets the ADSP-21061 to a known state and begins execution at the programmemory location specified by the hardware reset vector address. This input must be asserted (low) atpower-up.
TCK I Test Clock (JTAG). Provides an asynchronous clock for JTAG boundary scan.
TMS I/S Test Mode Select (JTAG). Used to control the test state machine. TMS has a 20 kΩ internal pull-upresistor.

TDO O Test Data Output (JTAG). Serial scan output of the boundary scan path.
TRST I/A Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low) after power-up or held low for proper operation of the ADSP-21061. TRST has a 20 kΩ internal pull-up resistor.

The 14-pin, 2-row pin strip header is keyed at the Pin 3 location —Pin 3 must be removed from the header. The pins must be0.025 inch square and at least 0.20 inch in length. Pin spacingshould be 0.1 × 0.1 inches. Pin strip headers are available fromvendors such as 3M, McKenzie and Samtec.
The BTMS, BTCK, BTRST and BTDI signals are provided sothe test access port can also be used for board-level testing.When the connector is not being used for emulation, placejumpers between the Bxxx pins and the xxx pins. If the test ac-cess port will not be used for board testing, tie BTRST to GNDand tie or pull BTCK up to VDD. The TRST pin must be as-serted after power-up (through BTRST on the connector) orheld low for proper operation of the ADSP-21061. None of theBxxx pins (Pins 5, 7, 9, 11) are connected on the EZ-ICE® probe.
The JTAG signals are terminated on the EZ-ICE® probe asfollows:

TARGET BOARD CONNECTOR FOR EZ-ICE® PROBEThe ADSP-21061 EZ-ICE®* Emulator uses the IEEE 1149.1JTAG test access port of the ADSP-21061 to monitor and con-trol the target board processor during emulation. The EZ-ICE®
probe requires the ADSP-21061’s CLKIN, TMS, TCK,TRST, TDI, TDO, EMU, and GND signals be made acces-sible on the target system via a 14-pin connector (a pin stripheader) such as that shown in Figure 5. The EZ-ICE® probeplugs directly onto this connector for chip-on-board emulation.You must add this connector to your target board design if youintend to use the ADSP-21061 EZ-ICE®. The length of thetraces between the connector and the ADSP-21061’s JTAGpins should be as short as possible.

Connecting CLKIN to Pin 4 of the EZ-ICE® header is optional.The emulator only uses CLKIN when directed to performoperations such as starting, stopping and single-stepping mul-tiple ADSP-21061s in a synchronous manner. If you do not needthese operations to occur synchronously on the multiple proces-sors, simply tie Pin 4 of the EZ-ICE® header to ground.
If synchronous multiprocessor operations are needed andCLKIN is connected, clock skew between the multiple ADSP-21061 processors and the CLKIN pin on the EZ-ICE®* headermust be minimal. If the skew is too large, synchronous operationsmay be off by one cycle between processors. For synchronousmultiprocessor operation TCK, TMS, CLKIN and EMU
should be treated as critical signals in terms of skew, and shouldbe laid out as short as possible on your board. If TCK, TMSand CLKIN are driving a large number of ADSP-21061s (morethan eight) in your system, then treat them as a clock tree usingmultiple drivers to minimize skew. (See Figure 7, JTAG ClockTree, and Clock Distribution in the High Frequency DesignConsiderations section of the ADSP-2106x User’s Manual.)
If synchronous multiprocessor operations are not needed (i.e.,CLKIN is not connected), just use appropriate parallel termina-tion on TCK and TMS. TDI, TDO, EMU and TRST are notcritical signals in terms of skew.

Exposure to absolute maximum rating conditions forextended periods may affect device reliability.
ESD SENSITIVITYThe ADSP-2106x processors are ESD (electrostatic discharge) sensitive devices. Electro-static charges readily accumulate on the human body and equipment and can dischargewithout detection. Permanent damage may occur to devices subjected to high energyelectrostatic discharges.
The ADSP-21061 processors include proprietary ESD protection circuitry to dissipatehigh energy discharges. Per method 3015 of MIL-STD-883, the ADSP-2106x processorshave been classified as a Class 2 device.
Proper ESD precautions are recommended to avoid performance degradation or loss offunctionality. Unused devices must be stored in conductive foam or shunts, and the foamshould be discharged to the destination socket before devices are removed.
TIMING SPECIFICATIONSGENERAL NOTESThis data sheet represents production released specifications forthe ADSP-21061 processor for 33 MHz and 40 MHz speedgrades. This data sheet also represents preliminary ac specifica-tions for the 50 MHz speed grade of the ADSP-21061.
The specifications shown are based on a CLKIN frequency of40 MHz (tCK = 25 ns). The DT derating allows specifications atother CLKIN frequencies (within the min–max range of the tCK
specification; see Clock Input below). DT is the difference be-tween the actual CLKIN period and a CLKIN period of 25 ns:

Use the exact timing information given. Do not attempt toderive parameters from the addition or subtraction of others.While addition or subtraction would yield meaningful results foran individual device, the values given in this data sheet reflectstatistical variations and worst cases. Consequently, you cannotmeaningfully add parameters to derive longer times.
See Figure 28 under Test Conditions for voltage referencelevels.
Switching Characteristics specify how the processor changes itssignals. You have no control over this timing—circuitry externalto the processor must be designed for compatibility with thesesignal characteristics. Switching characteristics tell you what theprocessor will do in a given circumstance. You can also use switch-ing characteristics to ensure that any timing requirement of a de-vice connected to the processor (such as memory) is satisfied.
Timing Requirements apply to signals that are controlled by cir-cuitry external to the processor, such as the data input for aread operation. Timing requirements guarantee that the proces-sor operates correctly with other devices.

POWER DISSIPATIONTotal power dissipation has two components, one due to inter-nal circuitry and one due to the switching of external outputdrivers. Internal power dissipation is dependent on the instruc-tion execution sequence and the data operands involved. Inter-nal power dissipation is calculated in the following way:
PINT = IDDIN × VDD
The external component of total power dissipation is caused bythe switching of output pins. Its magnitude depends on:
– the number of output pins that switch during each cycle (O)– the maximum frequency at which they can switch (f)– their load capacitance (C)– their voltage swing (VDD)
and is calculated by:
PEXT = O × C × VDD2 × f
The load capacitance should include the processor’s packagecapacitance (CIN). The switching frequency includes driving theload high and then back low. Address and data pins can drivehigh and low at a maximum rate of 1/(2tCK). The write strobecan switch every cycle at a frequency of 1/tCK. Select pins switchat 1/(2tCK), but selects can switch on each cycle.
Example:
Estimate PEXT with the following assumptions:
– A system with one bank of external data memory RAM (32-bit)– Four 128K × 8 RAM chips are used, each with a load of 10 pF– External data memory writes occur every other cycle, a rate of 1/(4tCK), with 50% of the pins switching
– The instruction cycle rate is 40 MHz (tCK = 25 ns) and VDD = 5.0 V.
The PEXT equation is calculated for each class of pins that candrive:
Pin # of %Type Pins Switching × C × f × VDD
2 = PEXT
Address 15 50 × 44.2 pF × 10 MHz × 25 V = 0.084 WMS0 1 0 × 44.2 pF × 10 MHz × 25 V = 0.000 WWR 1 – × 44.2 pF × 20 MHz × 25 V = 0.022 WData 32 50 × 14.7 pF × 10 MHz × 25 V = 0.059 WADDRCLK 1 – × 4.7 pF × 40 MHz × 25 V = 0.005 W
PEXT = 0.170 W
A typical power consumption can now be calculated for theseconditions by adding a typical internal power dissipation:
PTOTAL = PEXT + (IDDIN × 5.0 V )
Note that the conditions causing a worst-case PEXT are differentfrom those causing a worst-case PINT. Maximum PINT cannotoccur while 100% of the output pins are switching from all onesto all zeros. Also note that it is not common for an application tohave 100% or even 50% of the outputs switching simultaneously.
TEST CONDITIONSOutput Disable TimeOutput pins are considered to be disabled when they stop driv-ing, go into a high impedance state and start to decay from theiroutput high or low voltage. The time for the voltage on the busto decay by ∆V is dependent on the capacitive load, CL and theload current, IL. This decay time can be approximated by thefollowing equation:
tDECAY =
CL ∆VIL
The output disable time tDIS is the difference between tMEASURED
and tDECAY as shown in Figure 24. The time tMEASURED is theinterval from when the reference signal switches to when theoutput voltage decays ∆V from the measured output high oroutput low voltage. tDECAY is calculated with test loads CL andIL, and with ∆V equal to 0.5 V.
Output Enable TimeOutput pins are considered to be enabled when they have madea transition from a high impedance state to when they start driv-ing. The output enable time tENA is the interval from when a ref-erence signal reaches a high or low voltage level to when theoutput has reached a specified high or low trip point, as shownin the Output Enable/Disable diagram (Figure 24). If multiplepins (such as the data bus) are enabled, the measurement valueis that of the first pin to start driving.

System Hold Time CalculationTo determine the data output hold time in a particular system,first calculate tDECAY using the equation given above. Choose ∆Vto be the difference between the ADSP-21061’s output voltageand the input threshold for the device requiring the hold time. Atypical ∆V will be 0.4 V. CL is the total bus capacitance (perdata line), and IL is the total leakage or three-state current (perdata line). The hold time will be tDECAY plus the minimum dis-able time (i.e., tDATRWH for the write cycle).

Capacitive LoadingOutput delays and holds are based on standard capacitive loads:50 pF on all pins (see Figure 26). The delay and hold specifica-tions given should be derated by a factor of 1.5 ns/50 pF forloads other than the nominal value of 50 pF. Figures 28 showshow output rise time varies with capacitance. Figure 309 showsgraphically how output delays and holds vary with load capaci-tance. (Note that this graph or derating does not apply to outputdisable delays; see the previous section “Output Disable Time”under “Test Conditions.”) The graphs of Figures 28, 29 and 30may not be linear outside the ranges shown.

ENVIRONMENTAL CONDITIONSThermal CharacteristicsThe ADSP-21061 is packaged in a 240-lead thermally enhancedPQFP. The top surface of the package contains a copper slugfrom which most of the die heat is dissipated. The slug is flushwith the top surface of the package. Note that the copper slug isinternally connected to GND through the device substrate.The ADSP-2106x is specified for a case temperature (TCASE).To ensure that TCASE is not exceeded, a heat sink and/or an airflow source may be used. A heat sink should be attached with athermal adhesive.
TCASE = TAMB + ( PD × θCA )
TCASE = Case temperature (measured on top surface of package)
