3Fewer Chips Means Lower Cost

No More Design TradeoffsYou now spend time at the beginningof a project looking for the rightprocessor, and usually have to makemany tradeoffs because you can neverfind the microcontroller that has exactlythe peripherals you want. All that ischanged with PSoC. Your project nowstarts inside the development toolswhere you configure the PSoC blocks tothe peripheral set that is perfect for yourapplication. Further steps in theconfiguration process allow you toconnect these functions in sequence soyou can create signal chainsappropriate to your application.

PSoC BlocksThe analog and digital blocks thatsupport peripheral functions are calledPSoC blocks. These blocks are con-figured via register settings to perform awide range of functions. The inputs andoutputs from each block are also setwith register bits. Each of these blocks isdesigned to support a wide variety ofperipheral functions. Each digital PSoCblock is an 8-bit-wide resource.Therefore, creating an 8-bit Pulse WidthModulator (PWM) requires one digitalPSoC block. Two or more blocks can beused together to create wider-bit-widthfunctions. The analog PSoC blocks aredesigned around an operationalamplifier, and include programmablemultiplexing and programmablefeedback characteristics. There arethree types of analog blocks: acontinous time analog block that has a programmable resistor matrix in thefeedback path, and two types ofswitched capacitor blocks, which have switched capacitors in thefeedback path.

Standard Building Blocks for a Custom Design

Analog PSoC blocks aredesigned around an op amp and include

programmable multiplexingand programmable

feedback characteristics.

Multiple 8-bit-wide digital PSoCblocks can be used to create

16-, 24-, 32-, or higher-bit-widefunctions, such as a 16-bit timer.

User Modules We have made the configuration process easy by creating a library of user modules,which are pre-created, pre-tested configurationsof PSoC blocks to make peripherals. Uponselecting a particular user module, all the bit-level programming is done by the PSoC Designer software (the IntegratedDevelopment Environment), letting you focuson your application. A user module alsoincludes Application Program Interface (API)routines to communicate to the user module,and the necessary interrupt handling software.All the specifications for the user modules arein the PSoC Designer software. A typicaldigital user module is a UART, and a typicalanalog user module is a 12-bit incrementalADC. The large number of user modules tochoose from can eliminate requirements forexternal components, and can reduce theoverall parts count in your system.

User Modules: High-level Capabilities Map over PSoC blocks Automatically set registers for

configurations Implement standard peripherals Implement PSoC-unique peripherals


The Benefit of MultiplePeripherals from a SinglePSoC DeviceYou select the peripheral set andinterconnect by setting register values, andyou can also change these settings whilePSoC is running, thereby making acompletely different custom processor fordifferent states of your application. Thiscapability is called DynamicReconfiguration. Dynamic reconfigurabilityextends the peripheral capability beyondthe number of PSoC blocks on the originalPSoC. In every design there areperipherals that are used only occasion-ally, if at all. Wouldnt it be nice to getvalue from these peripherals and not justwaste them?

The PSoC development software enablesyou to create the second and subsequentconfigurations as easily as you create the first. The software interface that isrequired to switch between one config-uration and another is automaticallygenerated, so managing this change-of-state is as simple as a subroutine callfrom your application software.

Efficient Development Tools The development process starts inside thePSoC Designer software. This packageincludes all the tools you need to create andconfigure PSoC to meet the custom needs ofyour application. A simple graphicalinterface allows you to select the usermodules you want, place them on thehardware PSoC blocks, and interconnectthem with each other and the I/Os. Thetoolset also includes a C compiler and an In-Circuit Emulator (ICE) that has full-speedoperation, 128KBytes of trace memory, and complex breakpoints. Adapters arealso available to support emulation on alldevices in the PSoC family, and to convertthe ICE to a single-socket programmer for every device type. PSoC Designersoftware is available for free downloadfrom the Cypress MicroSystems web site(www.cypressmicro.com), and the develop-ment kit and C compiler are available forpurchase from the Cypress Online Store(www.onfulfillment.com/cypressstore).
