前言

在H8 / 532是一种高性能的单芯片日立独创的微型计算机，采用了高

高速CPU与16位内部数据通道和内部支持模块的完整补充。

在H8 / 532是一个理想的微控制器为各种各样的中等规模的设备，其中包括两

办公室和工业设备和消费产品。

其高度正交指令集是专为快速执行的程序编码中的高

级别C语言。

片内的设施包括大容量的RAM和ROM的记忆，无数的定时器，串行I / O ，一个A / D

转换器， I / O端口和其它功能的紧凑型实现高性能

应用系统。

在H8 / 532是既ZTAT 提供

*版本带有片上PROM ，非常适合早期阶段

生产或产品经常变化的规范，以及一个蒙面-ROM版

适合大批量生产。

本手册给出了H8 / 532的硬件描述。对于指令集的细节，请参考

该

H8 / 500系列编程手册，

它适用于在H8 / 500系列的所有芯片。
