High-Performance RISC CPU
:
   • Only 33 single word instructions to learn
   • All instructions are single cycle (1 ms) except for
program branches which are two-cycle
   • Operating speed: DC - 4 MHz clock input
                                  DC - 1 ms instruction cycle

   • 12-bit wide instructions
   • 8-bit wide data path
   • Seven special function hardware registers
   • Two-level deep hardware stack
   • Direct, indirect and relative addressing modes for data and instructions
   • Internal 4 MHz RC oscillator with programmable calibration
   • In-circuit serial programming
Peripheral Features:
   • 8-bit real time clock/counter (TMR0) with 8-bit programmable prescaler
   • Power-On Reset (POR)
   • Device Reset Timer (DRT)
   • Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation
   • Programmable code-protection
   • 1,000,000 erase/write cycle EEPROM data memory
   • EEPROM data retention > 40 years
   • Power saving SLEEP mode
   • Wake-up from SLEEP on pin change
   • Internal weak pull-ups on I/O pins
   • Internal pull-up on MCLR pin
