Preface
The H8/338 Series is a series of high-performance single-chip microcomputers having a fast
H8/300 CPU core and a set of on-chip supporting functions optimized for embedded control.
These include ROM, RAM, three types of timers, a serial communication interface, an A/D
converter, a D/A converter, I/O ports, and other functions needed in control system configurations,
so that compact, high-performance systems can be realized easily. The H8/338 Series includes
three chips: the H8/338 with 48K-byte ROM and 2K-byte RAM; the H8/337 with 32K-byte ROM
and 1K-byte RAM; and the H8/336 with 24K-byte ROM and 1K-byte RAM.
The H8/338 and H8/337 are available in a masked ROM version, a ZTAT
*(Zero Turn-Around
Time) version, and a ROMless version, providing a quick and flexible response to conditions from
ramp-up through full-scale volume producion, even for applications with frequently-changing
specifications.
This manual describes the hardware of the H8/338 Series. Refer to the H8/300 Series
Programming Manual for a detailed description of the instruction set.
