DEVICE OVERVIEW

This document contains device-specific information for the following devices:

? PIC18F65K22 ? PIC18F85K22

? PIC18F66K22 ? PIC18F86K22

? PIC18F67K22 ? PIC18F87K22

This family combines the traditional advantages of all PIC18 microcontrollers – namely, high computational performance and a rich feature set – with an extremely competitive price point. These features make the PIC18F87K22 family a logical choice for many high-performance applications where price is a primary consideration.
