New, Higher-Performance Members Added To Popular Flash Controller Family

Expanding the PICmicro flash microcontroller line is a family of 14-pin devices that feature an A/D converter, internal oscillator, a comparator, and quick start-up. The PIC16F630 and PIC16F676 devices employ the company's PMOS electrically erasable cell (PEEC) process technology, which promises best-in-class erase/write endurance, retention and disturb reliability for both program and on-chip data EEPROM memory. Both are code-compatible with the current PIC12F629 and PIC12F675 8-pin flash devices. Other features include a typical standby current of 100 nA at 2V, an operating voltage range of 2V to 5.5V, a startup time of 2 µs, and the ability to run a timer from an external crystal while in sleep mode. In terms of memory, both devices include 1,792 bytes of flash program memory, 64 bytes of RAM, and 128 bytes of EEPROM with 1,000,000 erase/write cycles. The PIC16F676 integrates a 10-bit A/D converter with eight channels that can use either VDD or an external voltage reference. Peripherals available on both devices include an internal oscillator that is ±2% stable, a comparator with an internal voltage reference with 32 selectable voltage levels, and brownout reset. Available in 14-pin TSSOP, PDIP and SOIC packages, the PIC16F630 and PIC16F676 are priced in volume quantities at $0.79 and $0.91 each, respectively. MICROCHIP TECHNOLOGY INC., Chandler, AZ.
