Product Introduction

概述
P80C652/83C652单芯片8位微控制器通过高级CMOS工艺制造，是80C51微控制器系列的衍生产品。80C652/83C652与80C51具有相同的指令集。存在三个版本的衍生产品：

83C652 - 8k字节掩模可编程ROM

80C652 - 无ROM版

87C652 - EPROM版（在单个章节中介绍）

该设备提供了架构增强功能，使得其可适用于一般控制系统的各种应用。8XC652包含一个非易失性8k ? 8只读程序存储器，一个易失性256 ? 8读/写数据存储器，四个8位I/O端口，两个16位定时器/事件计数器（与80C51定时器类似），一个多源，两优先级嵌套中断结构，一个I²C接口，UART和片内振荡器以及定时电路。对于需要额外功能的系统，8XC652可以使用标准TTL兼容内存和逻辑进行扩展。

该设备还具有算术处理器功能，同时具有二进制和BCD算术以及位处理能力。指令集包括超过100个指令：49个单字节、45个双字节和17个三字节。凭借16(24)MHz晶体，58%的指令在0.75（0.5）微秒内执行，40%在1.5（1）微秒内执行。乘和除指令需要3（2）微秒。
