The PIC16F630/676 microcontroller products merge
all the advantages of the mid-range x14 architecture
and the flexibility of Flash program memory into a
14-pin package. The PIC16F6XX devices feature a
14-bit instruction set, small footprint package, and a
wide operating voltage of 2.0-5.5 volts. In addition,
these devices offer an internal programmable 4 MHz
oscillator, on-board EEPROM data memory, on-chip
voltage reference, and up to 8 channels of 10-bit A/D.
These 14-pin microcontrollers provide the features and
intelligence not previously available due to cost and
board space limitations. With the flexibility of Flash
and an excellent development tool suite including a
low cost In-Circuit Debugger (ICD), In-Circuit Serial
Programming™ (ICSP™) and full ICE 2000 emulation,
these devices are ideal for just about any embedded
control application.
