Section 1 Overview
1.1 Overview
The H8/3032 Series is a series of microcontrollers (MCUs) that integrate system supporting
functions together with an H8/300H CPU core having an original Hitachi architecture.
The H8/300H CPU has a 32-bit internal architecture with sixteen 16-bit general registers, and a
concise, optimized instruction set designed for speed. It can address a 16-Mbyte linear address
*1
space.
Its instruction set is upward-compatible at the object-code level with the H8/300 CPU,
enabling easy porting of software from the H8/300 Series.
The on-chip system supporting functions include ROM, RAM, a 16-bit integrated timer unit
(ITU), a programmable timing pattern controller (TPC), a watchdog timer (WDT), a serial
communication interface (SCI), an A/D converter, I/O ports, and other facilities.
The three members of the H8/3032 Series are the H8/3032, the H8/3031, and the H8/3030. The
H8/3032 has 64 kbytes of ROM and 2 kbytes of RAM. The H8/3031 has 32 kbytes of ROM and
1 kbyte of RAM. The H8/3030 has 16 kbytes of ROM and 512 bytes of RAM.
Three MCU operating modes offer a choice of data bus width and address space size. The modes
(modes 1 to 3) include a single-chip mode and expanded mode.

In addition to the masked-ROM versions of the H8/3032 Series, the H8/3032 has a ZTAT™
version with user-programmable on-chip PROM. This version enables users to respond quickly
and flexibly to changing application specifications, growing production volumes, and other
conditions.
Table 1-1 summarizes the features of the H8/3032 Series.
Notes: 1. The H8/3032 Series has a maximum address space of 1 Mbyte.
2. ZTAT (Zero Turn-Around Time) is a trademark of Hitachi, Ltd.
