8-bit PIC® Microcontrollers

8-bit Architecture Overview

  • Increased efficiency single cycle instructions
  • Available data EEPROM
  • Unified toolset for all cores
  • Instructions and data on separate busses
  • Simultaneous data & instruction bus access
  • Wide program memory buses (12, 14 & 16-bit)
