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.
