• 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
