To all our customers
Regarding the change of names mentioned in the document, such as
Hitachi Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were
transferred to Renesas Technology Corporation on April 1st 2003.
These operations include microcomputer, logic, analog and discrete devices,
and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors,
and other Hitachi brand names are mentioned in the document, these names
have in fact all been changed to Renesas Technology Corp.
Thank you for your understanding. Except for our corporate trademark,
logo and corporate statement, no changes whatsoever have been made to the
contents of the document, and these changes do not constitute any alteration
to the contents of the document itself.

Section 1. Overview
1.1 Overview
The H8/329 Series of single-chip microcomputers features an H8/300 CPU core and a complement
of on-chip supporting modules implementing a variety of system functions.
The H8/300 CPU is a high-speed processor with an architecture featuring powerful bit-
manipulation instructions, ideally suited for realtime control applications. The on-chip supporting
modules implement peripheral functions needed in system configurations. These include ROM,
RAM, two types of timers (a 16-bit free-running timer and 8-bit timers), a serial communication
interface (SCI), an A/D converter, and I/O ports.
The H8/329 Series can operate in a single-chip mode or in two expanded modes, depending on the
requirements of the application. (The operating mode will be referred to as the MCU mode in this
manual.)
The entire H8/329 Series is available with masked ROM. The H8/329 and H8/327 are also
available in ZTAT™ versions* that can be programmed at the user site, and in ROMless versions.
Notes: * ZTAT is a registered trademark of Hitachi, Ltd.
Table 1-1 lists the features of the H8/329 Series.
