Summary of Microchip: Cost-Effective 14-Pin PICmicro® Flash Microcontrollers
Microchip launched the PIC16F630 and PIC16F676, low-pin count microcontrollers featuring integrated ADCs, precision oscillators, comparators, and Brownout Reset. These 14-pin devices utilize PMOS technology for high endurance and are code-compatible with existing 8-pin PIC12 series parts. They offer wide voltage operation (2V–5.5V), ultra-low standby current (100 nA), and quick startup capabilities ideal for battery-powered applications.
Parts used in the PIC16F630 and PIC16F676 Microcontrollers:
- PIC16F630 microcontroller
- PIC16F676 microcontroller
- Integrated analogue-to-digital converter (ADC)
- Precision internal oscillator
- Comparator with internal voltage reference
- Brownout Reset
- Flash program memory
- RAM
- Data EEPROM
- Timer capable of running from external crystal in SLEEP mode
(PRWEB) November 2, 2002
Microchip’s family of low-pin count PICmicroâ Flash microcontrollers features integrated analogue-to-digital converter, precision internal oscillator, comparator and quick start-up. 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 100 nA at 2.0V and a wide operating voltage range from 2V to 5.5V. A quick start-up of 2 µs 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 1792 bytes of Flash program memory, 64 bytes of RAM and 128 bytes of EEPROM. The PIC16F676 features a 10-bit ADC with 8 channels that can use either VDD or an external voltage reference. Both devices include a precision internal oscillator that is +/-2 percent 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. For more information visit http://www.microchip.com.
