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.

HARDWARE MANUAL
Preface
The H8/330 is a high-performance single-chip microcomputer ideally suited for embedded control
of industrial equipment. Its core is the H8/300 CPU: a high-speed processor. On-chip supporting
modules provide memory, I/O, and timer functions, including:
• 16K bytes of on-chip ROM
• 512 bytes of on-chip RAM
• 15 bytes of dual-port RAM for a master-slave interface
• Serial I/O
• General-purpose I/O ports
• A/D converter
• Timers
Compact, high-performance control systems can be built using the H8/330.
The H8/330 is 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 H8/330 hardware. Refer to the
H8/300 Series Programming Manual
for
a detailed description of the instruction set.
