Support for small processors grows
By Robert Cravotta -- EDN, July 25, 2005
Microchip’s support of small processors includes new PIC devices, a new 4×4-mm QFN package option for 14 devices ranging from eight to 20 pins, upgraded development tools, and a PICDEM demonstration board. The new processor devices include the PIC16F690 family that incorporates improved peripherals, such as a new dual-comparator peripheral architecture. The PIC16F690 family devices are available for sampling and in volume production in 20-pin PDIP, SOIC, SSOP, and QFN packages with pricing starting at $1.78 (10,000). In addition to the new comparator architecture, the PIC16F506/12F510 devices feature a 1.125-msec device-reset timer and a faster internal oscillator that can operate at 8 MHz with strong stability across its rated voltage and temperature range. Both devices are available for general sampling with volume production planned for late 2005. The PIC12F510 sells for 81 cents (10,000), and the PIC16F506 cells for 90 cents (10,000).
The small-form-factor PIC10F222/10F222 family integrates an 8-bit ADC in an SOT-23 package that is the size of a transistor. These devices are available for limited sampling in six-pin SOT-23 packages; volume production for both microcontrollers will begin in the fourth quarter of 2005. The processors are available for 65 to 74 cents (10,000). The PIC16F639 family rounds out the new device offerings by featuring a 125-kHz wireless-communication analog front end and Keeloq security to target passive-keyless-entry applications. The PIC16F639 is available for sampling in a 20-pin SSOP package, volume production will begin in the third quarter; the PIC16F639 sells for $2.18 (10,000).
To better support software development, the PICkit 2 starter kit will become available to designers in August for as little as $34.99. The PICdem Mechatronics demonstration kit shows engineers how to use the PIC microcontrollers in electromechanical or mechatronic systems; the kit includes nine projects showing designers how to read sensors, drive brush dc or stepper motors, and display values on LEDs or LCDs. The PICdem is available for $149.99.
