devices enable

new markets for

microcontrollers:

“Electronic Glue”,

Logic Control and more

For highly space-constrained and low-cost applications, the world’s smallest microcontrollers – in 6-pin packages pack the high-performance of the PIC microcontroller architecture into the ultra-small form factor of a SOT-23 package. These revolutionary 6-pin Flash devices provide an ideal solution for many markets and uses not typically served by microcontrollers today, including “Electronic Glue” to enable easy bug fi xes for ASIC and Printed Circuit Board (PCB) designs and replaces standard logic and timing components or traditional mechanical timers and switches.

“Microchip continues to push the limits of the 8-bit microcontroller,

creating a new breed of ultra small Flash devices that are opening the

door to non-traditional uses for the PIC microcontroller,” said Steve

Drehobl, Vice President of Microchip’s Security, Microcontroller and

Technology Development Division. “The 6-pin devices provide a

cost-effective replacement for many discrete logic or mechanical

functions, substantially reducing component count and board space

while giving engineers additional design fl exibility.”

The PIC10F 8-bit Flash microcontroller family debuts with four devices: (PIC10F200, PIC10F202, PIC10F204, PIC10F206)

Signifi cant features of these PIC microcontrollers include:

• 256 to 512 instructions (x12-bit program words) of Flash program memory.

• 6 bytes to 24 bytes of data RAM memory.

• Precision 4 MHz internal oscillator, 33 instructions, two stack levels.

• 25 milliamp source/sink current IO, low power (100 nanoamp) sleep current.

• Wide operating voltage range from 2 to 5.5 volts, one 8-bit timer and a watchdog

timer.

• In Circuit Serial Programming™ (ICSP) technology, power-on reset, power-saving

Sleep mode.

• An analog comparator module (in the PIC10F204 and PIC10F206 only). With only

six pins, they are very simple to use and have a short learning curve for anyone not

experienced in designing with microcontrollers.

Through ICSP™ technology, Microchip’s 6-pin devices can be programmed after placement on a circuit board. ICSP technology enables fi eld upgrades, system calibration during manufacturing and the addition of unique identifi cation codes to the system.

Enabling New Applications for Microcontrollers:

While the PIC10F family is ideal for any spaced-constrained application requiring low pin count microcontrollers, the combination of small form factor, high-performance and low-cost is creating new applications not traditionally served by microcontrollers. The following are a few examples:

Electronic Glue:

Discovering a bug in an ASIC or a PCB can have devastating consequences for the design. A revision to the silicon or a complete board change may be required, creating substantial time-to-market delays and potential scrappage costs. Often, the design issue is simple and can be accommodated by changing the functionality of a single signal using a small, low-cost microcontroller.

The development time for a microcontroller-based system is signifi cantly faster and easier than designing an entirely new ASIC or PCB. By including the low-cost PIC10F 6-pin devices in a PCB design from the start, bugs, late changes and other stopgaps can be implemented with ease and little expense for ASICs, the board itself and for a number of other devices on the PCB.

Logic Control:

Traditional standard logic and timing components, such as delays, smart gates, signal conditioning, simple state machines, encoders/decoders, I/O expanders and small peripheral logic functions can now be cost effectively integrated into a 6-pin microcontroller. The advantages include:

• Eliminating components (reducing board space and cost).

• Allowing the implementation of more complex solutions by using fi rmware to implement state machines.

• Enabling designers to change the functionality on the PCB without having to replace the actual board.

Waveform Generation:

As with replacing standard logic devices, a PIC10F microcontroller can take the place of traditional 555 timers, pulse-width modulators (PWMs), remote control encoders, pulse generation, programmable frequency source, resistor-programmable oscillators and much more.

“Mechatronics”/Mechanical Functions:

The PIC10F devices are an ideal solution to replace traditional mechanical functions, such as smart switches, mode selectors, remote I/Os, timers, LED fl ashers and any other form of mechanical timers and switches. A microcontroller solution, in general, can add signifi cantly more functionality than a mechanical-based device.

4-bit Microcontrollers:

Physically smaller and higher in performance, Microchip’s 8-bit, 6-pin SOT-23 microcontroller provides a more robust solution over 4-bit microcontrollers in larger packages. Additionally, writing software code for an 8-bit microcontroller is much easier than with 4-bit devices, in many cases. In terms of cost effectiveness, the PIC10F devices are priced at or below current 4-bit microcontroller cost baselines.

Intelligent Disposable Electronics:

Given their small form factor and low cost, the PIC10F are ideal for many emerging “disposable” applications that incorporate electronics intelligence, like property identifi cation. This includes a growing number of medical equipment products such as pregnancy testers, dialysis monitoring (blood sugar) and drug testers.

Device extends battery life; offers open-drain

output and push-pull

Microchip Offers Low Power, Low Voltage Detector In a Space-Saving Package

This family of low-power devices can operate on a supply voltage as low as 1V and typically consume less than 1 microamp of current.

The MCP111 (open-drain output) and MCP112 (push-pull output) are ultra low-power voltage detectors offered in a 3-pin SOT-23, SC-70 and TO-92 package. The combination of low power, small packages and low cost makes these devices ideal for many portable and consumer-electronics applications where space and power consumption are critical. Noisy environments and unreliable power sources may create a variety of system-level problems for microcontrollers that can be eliminated with a power-on reset function. These power-on reset devices are designed to hold the microcontroller in reset until the supply voltage reaches a stable, predetermined operating level. These devices also protect against brown-out conditions that occur as a result of the supply voltage dropping below a tolerable operating level.

These attachable devices are synergistic with Microchip’s PIC® microcontrollers featuring nanoWatttechnology. The low operating current of the MCP111/112, combined with the PIC microcontroller featuring nanoWatt technology power-managed modes, enables total control of system power consumption.

The appliance market is in the middle of a paradigm shift. Product designs that have traditionally been a mixture of mechanical and analog components are swiftly migrating into the digital realm. Microcontrollers, now as small as a 6-pin SOT-23, are improving the performance and safety of appliances by adding intelligence to what were once dim-witted machines. Take a coffee maker for instance. Mid-range coffee makers are now offering features like automatically brewing a pot of coffee for you when you wake up. These makers can also automatically shut themselves off if left unattended. We’re going to take a look at the migration from a basic coffee maker to one with some added features in the next few paragraphs.

Let’s first take a look at your average no-frills coffee maker. You can walk down to your local department store and pick up one of these coffee makers for around $20. The electric components in the coffee maker consist of a power cord, a 120V AC switch, a couple of fuses, a heating element and a thermal breaker. The purpose of the heating element is two-fold. One, it heats water in an adjacent metal tube. The water turns to steam and rises to the top of the pot where it re-condenses and percolates through the coffee grounds. Secondly, the heating element keeps the pot warm once the coffee is made. Your coffee is prevented from getting too hot by the thermal breaker. Its job is to sense when the heating element reaches a certain temperature and then trip, causing a break in the circuit. After the heating element cools, the thermal breaker resets and the process starts all over again. Your coffee is warm and tasty but if you‘re not around to turn off the maker, your coffee will soon turn into a thick coffee sludge and then evaporate altogether, except for a baked-on brown crust in your pot. In our digital world, we demand more of our coffee makers, don’t we?

Enter the PIC microcontroller, along with the transformerless power supply and a few other necessary components. For less than 50 cents, you can buy the components necessary to create a resistive transformerless power supply (see Figure 1.) This will allow you to power a microcontroller, such as the PIC16F675, directly from 110V AC. Now, your coffee maker has brains! Two more essential systems are needed: a way to sense the temperature of the heating element and a way to vary the current to the heating element.

The temperature of the heating element can be determined in a cost-effective way by sensing the current through the heating element. The resistance of the heating element is a function of the temperature of the element. Current is inversely proportional to resistance. A sense resistor in parallel with the heating element creates a way to sense the current consumed by the heating element. A differential amplifier is used to magnify the voltage changes across the sense resistor. This voltage is measured using an analog-to-digital converter channel on the PIC12F675.

A triac in series with the heating element provides a way for the microcontroller to vary the current to the heating element. The zero crossing point of the AC waveform is sensed by pin 2 in the circuit shown. This gives the microcontroller a reference point from which to switch the triac on and off. If the hot plate has reached its optimal temperature, for instance, the triac can switch on, alternating periods of the AC waveform in order to maintain a constant temperature.

Compared to the no-frills coffee maker, the microcontroller-based coffee maker will allow the coffee to stay at a constant temperature in addition to providing auto-shutdown capability. A number of other features can be added, once a microcontroller is on-board including an LED display, a clock readout, or automatic start-up. The total cost of this upgrade comes to about $2 at the component level. To be sure, the consumer will see a price increase several times this amount, but for the added functionality and flair most are willing to pay it.

TIP 1. Low Energy Power Supplies

Designing the power supply for a low-power device can be very tricky. There are many considerations including:

1. Battery Capacity

2. Internal Battery Resistance

3. Battery Size

4. Battery Cost

5. Battery Weight

6. Voltage Regulator Minimum Regulation Voltage

7. Voltage Regulator Quiescent Current

Batteries come in all shapes, sizes and chemistry. A small, high capacity battery typically has a higher internal resistance, so it is less useful for high-current applications. Batteries good for high current generally have lower capacity and higher weight than a similar sized high resistance battery. Examples are NiCd and NiMh. The NiMh battery is low in weight, high in capacity and small in size. However, it has a much higher internal resistance than the NiCd. Rapid discharge of the NiMh will seriously decrease the life. The high internal resistance will not affect most low current applications, but if the application requires a burst of current, it is possible for the voltage to sag and the PICmicro® MCU could reset. Think of a RF transponder. Most of the time it is sitting idle, but upon demand, it must produce a powerful radio burst.

If VDD must be kept constant or the battery voltage is too large, a voltage regulator may be used in the application. If you add a voltage regulator, you increase the current consumption by the

quiescent current of the regulator (the current used by the regulator to regulate).

TIP 2. I/O Device Control (continued)

TIP 3. Low Power Timer1

Applications requiring Timer1 to have a clock crystal connected to its T1OSO and T1OSI pins must take PCB layout into consideration. The new low-power Timer1 consumes very little current, therefore making its oscillator circuit sensitive to neighboring circuits.

To start, the oscillator circuit (including crystal and capacitors) should be located as close as possible to the microcontroller. Other than VDD and VSS, no other circuits should be passing through the oscillator boundaries. If it is unavoidable to have high-speed circuits around the oscillator circuit, then a guard ring should be placed around the oscillator circuit and microcontroller pins similar to the fi gure shown here. It would also help to have the oscillator’s circuit placed over a ground plane.

(CONTINUED)

TIP 2. I/O Device Control

When power consumption is crucial in an application, designers look for ways of saving as much power as possible. The fi rst obvious way is to put the microcontroller to SLEEP when there is no need for it to be running. Another solution is to clock the device at a lower frequency to consume less current. If there are other ICs on the PCB, it is possible to use an I/O pin to turn them off and on when they are not needed. Some of these ICs have a control pin dedicated for this (see Figure 1). What if there is no dedicated control pin? The I/O pin can be tied to the VDD pin of the devices. There are limitations to this. The device can not draw more than the rated source current of the microcontroller I/O pin and must have a VDD requirement equal to the microcontroller’s VDD. An alternative would be to tie an output pin to control a switch, which controls power to other devices.

TIP 4. Clock Switching PIC16F Dual Clock

TIP 5. Config Port

Although the following practice may seem routine, PORT I/O initialization is overlooked many times. On a POR (Power-on Reset), the PORT registers (Ex. PORTB) have an unknown value. If the TRIS registers (Ex. TRISB) are confi gured before the PORT registers are set or cleared, unexpected code behavior can result. The instruction sequence below is an example of how I/O initialization should be handled.

Example: Clear PORTB and confi gure all PORTB I/O as outputs:

clrf TRISB ;confi gure for outputs

The PIC16F62X devices are equipped with a second, low-speed internal oscillator. This oscillator is available when the device is operating from Internal RC (INTRC), External RC* (EXTRC), or External Resistor** (ER) modes. It can be used to operate the microcontroller at low speeds for reduced power consumption. The actual speed of this oscillator is not calibrated, so expect 20% - 40% variability in the oscillator frequency.

To change oscillators, simply toggle bit 3 (OSCF) in the PCON register. If the bit is clear, the low-speed oscillator is used. If the bit is set, then the oscillator confi gured by the CONFIG bits is used.

* EXTRC mode only available on A parts. ** ER mode only available on the non-A parts.

All PICmicro® MCUs have bi-directional I/O pins. Some of these pins have analog input capabilities. It is very important to pay attention to the signals applied to these pins so the least amount of power will be consumed.

Digital Inputs:

A digital input pin consumes the least amount of power when the input voltage is near VDD orVSS. If the input voltage is near the midpoint between VDD and VSS, the transistors inside the PICmicro MCU are biased in a linear region, and they will consume a signifi cant amount of current. This current drain is most likely to occur if the application uses pin-overloading tricks, such as using a charging capacitor to read multiple switches or driving many LEDs from a few I/O pins. Sometimes it may be better to reconfi gure inputs to outputs to hold a known condition and minimize current.

Digital Outputs:

There is no additional current consumed by a digital output pin other than the current goingthrough the pin to power the external circuit. Pay close attention to the external circuits to minimize their current consumption. Pay special attention to any bias circuits or pull-up/down

circuits that may be required.

Analog inputs:

Analog inputs are very high impedance so they consume very little current. They will consume less current than a digital input if the applied voltage would normally be centered between VDD

and VSS. Sometimes it is appropriate and possible to confi gure digital inputs as analog inputs when the digital input must go to a low-power state.

Pay attention to the behavior of the pins and determine what the pin I/O state must be whenentering and leaving each Power mode. The wrong choice for one pin can cause a signifi cantpower increase and destroy the life of the application.

TIP 6. I/O Initialization

TIP 7. Two-Speed Start-up

This feature is new to the PIC® microcontroller family and is available on some of the nanoWatt Technology devices. Using the internal oscillator, it allows the user to execute code, while waiting for the Oscillator Start-up (OST) timer to expire (LP, XT or HS Modes). This feature is enabled through the IESO confi guration bit. By the default setting of the OSCCON register, Two-Speed Start-up will clock the device from the INTRC (32 kHz) until the OST has expired. Switching to a faster internal oscillator frequency can optimize this feature. The example below shows several stages on how this can be achieved. The number of frequency changes is dependent upon the designer’s discretion. Assume a 20 MHz crystal (HS Mode) in the PIC18F example shown below.
