GENERAL DESCRIPTION

The PIC12C67X devices are low-cost, high-perfor mance, CMOS, fully-static, 8-bit microcontrollers with integrated analog-to-digital (A/D) converter and EEPROM data memory (EEPROM on PIC12CE67X versions only).

High-Performance RISC CPU:

? Only 35 single word instructions to learn

? All instructions are single cycle (400 ns) except for program branches which are two-cycle

? Operating speed: DC - 10 MHz clock input

DC - 400 ns instruction cycle

? 14-bit wide instructions

? 8-bit wide data path

? Interrupt capability

? Special function hardware registers

? 8-level deep hardware stack

? Direct, indirect and relative addressing modes for data and instructions

Peripheral Features:

? Four-channel, 8-bit A/D converter

? 8-bit real time clock/counter (TMR0) with 8-bit programmable prescaler

? 1,000,000 erase/write cycle EEPROM data memory

? EEPROM data retention > 40 years

Special Microcontroller Features:

? In-Circuit Serial Programming (ICSP?)

? Internal 4 MHz oscillator with programmable calibration

? Selectable clockout

? Power-on Reset (POR)

? Power-up Timer (PWRT) and Oscillator Start-up Timer (OST)

? Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation

? Programmable code protection

? Power saving SLEEP mode

? Interrupt-on-pin change (GP0, GP1, GP3)

? Internal pull-ups on I/O pins (GP0, GP1, GP3)

? Internal pull-up on MCLR pin

? Selectable oscillator options:

- INTRC: Precision internal 4 MHz oscillator

- EXTRC: External low-cost RC oscillator

- XT: Standard crystal/resonator

- HS: High speed crystal/resonator

- LP: Power saving, low frequency crystal

CMOS Technology:

? Low-power, high-speed CMOS EPROM/EEPROM technology

? Fully static design

? Wide operating voltage range 2.5V to 5.5V

? Commercial, Industrial and Extended temperature ranges

? Low power consumption

< 2 mA @ 5V, 4 MHz
