Microchip's low-pin-count PICmicro Flash microcontrollers feature integrated analogue-to-digital convertor, precision internal oscillator, comparator and quick startup.

The new PIC16F630 and PIC16F676 microcontrollers use Microchip's PMOS electrically erasable cell process technology which provides best-in-class erase/write endurance, retention, and disturb reliability for both program memory and on-chip data EEPROM.

The 14-pin packaging is similar in size to 8-pin devices and considerably smaller than 18-pin devices.

The microcontrollers are code-compatible with Microchip's current PIC12F629 and PIC12F675 8-pin Flash devices, providing an inexpensive upgrade for existing designs.

The devices offer a typical standby current of 100nA at 2.0V and a wide operating voltage range from 2 to 5.5V.

A quick start-up of 2us and the ability to run a timer from an external crystal while in sleep mode makes them ideal for low power applications.

The devices include 1792byte of Flash program memory, 64byte of RAM and 128byte of EEPROM.

The PIC16F676 features a 10bit ADC with eight channels that can use either VDD or an external voltage reference.

Both devices include a precision internal oscillator that is +/-2% stable over a wide temperature and voltage range, a comparator with an internal voltage reference with 32 selectable voltage levels and brownout reset.

The devices are available in 14-pin TSSOP, PDIP and SOIC packages.
