MC68HC705KJ1CP集成電路（IC）的微控制器規(guī)格書PDF中文資料

Introduction

Freescale provides two different parts to migrate your current MC68HC705K1 (K1) application easily. Depending on your design, system enhancements, and cost, the MC68HC705KJ1 (KJ1) and the MC68HC805K3 (K3) provide two different migration paths.

The major differences between the KJ1 and the K3 are:

? Price

? Pinout compatibility

The KJ1 is not pin for pin the same as the K1, but it is roughly 70 the cost of the K1. Although the K3 is pin for pin the same as the K1, it is roughly 90 the cost of the K1.

This application note illustrates the differences between the K1 and the

KJ1. Using the KJ1’s additional features can further enhance your

system design. Consult the K1 and KJ1 databooks for detailed design

reference. See References/Additional Reading in this application
