Fifty cents goes much farther than it used to in the 8-bit microcontroller market. Microchip is selling the PIC16C505 one-time-programmable (OTP) part for 49 cents, and the PIC16CR54C ROM device for 40 cents. The 14-pin parts provide an upward migration path to increased I/O capability for designs based on the company's 8-pin controllers. The OTP part sports 1,024312 words of program memory, 72 x 8 bytes of user RAM, 12 I/O pins, and a 4-MHz internal clock oscillator. The ROM version offers 512 x 12 words of ROM program memory, 25 bytes of user RAM, and 12 I/O pins. Both operate from 2.5 to 5.5V, use 33 single-word instructions, and offer a full-speed 200-nsec instruction cycle at 20 MHz. Microchip Technology: Product Code 4277
