Section 1. Overview
1.1 Overview
The H8/325 Series is a series of single-chip microcomputers integrating a CPU core together with a
variety of peripheral functions needed in control systems.
The H8/300 CPU is a high-speed processor featuring powerful bit-manipulation instructions,
ideally suited for realtime control applications. The on-chip supporting modules include ROM,
RAM, two types of timers (16-bit free-running timer and 8-bit timer), a serial communication
interface, I/O ports, and a parallel handshaking interface. The on-chip memory sizes of the three
chips in the H8/325 Series are:
H8/3257: 60-kbyte ROM; 2-kbyte RAM
H8/3256: 48-kbyte ROM; 2-kbyte RAM
H8/325: 32-kbyte ROM; 1-kbyte RAM
H8/324: 24-kbyte ROM; 1-kbyte RAM
H8/323: 16-kbyte ROM; 512-byte RAM
H8/322: 8-kbyte ROM; 256-byte RAM
The H8/325 Series can operate in single-chip mode or in two expanded modes, depending on the
memory requirements of the application. The operating mode is referred to in this manual as the
MCU mode (MCU: MicroComputer Unit).
The H8/3257, H8/3256, H8/325, H8/323, and H8/322 are available in a masked ROM version, or a
ZTAT™* version with electrically programmable ROM that can be programmed at the user site.
