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
