DEVICE OVERVIEW
This document contains device specific information for the following devices:

• PIC18F2220 • PIC18F4220
• PIC18F2320 • PIC18F4320

This family offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price with the addition of high endurance Enhanced Flash program memory. On top of these features, the PIC18F2220/2320/4220/4320 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications.
