Overview

Features

The H8/532 is an original Hitachi CMOS microcomputer unit (MCU) comprising a highperformance CPU core plus a full range of supporting functions—an entire system integrated onto a single chip.

The CPU features a highly orthogonal instruction set that permits addressing modes and data sizes to be specified independently in each instruction. An internal 16-bit architecture and 16-bit access to on-chip memory enhance the CPU’s data-processing capability and provide the speed needed for realtime control applications.

The on-chip supporting functions include RAM, ROM, timers, a serial communication interface (SCI), A/D conversion, and I/O ports. An on-chip data transfer controller (DTC) can transfer data in either direction between memory and I/O independently of the CPU.

For the on-chip ROM, a choice is offered between masked ROM and programmable ROM (PROM). The PROM version can be programmed by the user with a general-purpose PROM writer.
