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
