PIC18F87K22T-I/MR中文资料微芯科技数据手册PDF规格书

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.
