Preface
The H8/325 Series is a family of high-performance single-chip microcomputers ideally suited for
embedded control of industrial equipment. The chips are built around an H8/300 CPU core: a high-
speed processor. On-chip supporting modules provide ROM, RAM, two types of timers, I/O ports,
and a serial communication interface for easy implementation of compact, high-speed control
systems.
The H8/325 Series offers a selection of on-chip memory.
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 H8/3257, H8/3256, H8/325, H8/323, and H8/322 chips are available with either electrically
programmable or mask-programmable ROM. Manufacturers can use the electrically programmable
ZTAT™ (Zero Turn-Around Time*) version to get production off to a fast start and make software
changes quickly, then switch over to the masked version for full-scale production runs.
This manual describes the H8/325 Series hardware. Refer to the H8/300 Series Programming
Manual for a detailed description of the instruction set.
