1.1 Overview
The H8/338 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, three types of timers (16-bit free-running timer, 8-bit timers, pulse-width modulation
timers), a serial communication interface (SCI), an A/D converter, a D/A converter, and I/O ports.
The H8/338 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 H8/338 Series is available with masked ROM. The H8/338 and H8/337 are also
available in ZTAT
versions* that can be programmed at the user site, and in ROMless versions.
