12C671

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
