Preface
Hitachi’s H8S family of single-chip microcomputers comprises a number of new series offering
the high performance and low power consumption of the existing H8 Series, which is widely used
for machine control, etc., together with significantly greater ease of use.
The H8S/2000 Series features CPU object-level compatibility with the H8/300H Series, H8/300
Series, and H8/300L Series within the H8 Series.
Series
H8S/2000
H8/300H
Features
Upward-compatible with the H8/300H Series and H8/300 Series; twice the
performance at the same frequency
16-Mbyte linear address space; upward-compatible with the H8/300 Series;
concise instruction set; powerful word-size and longword-size arithmetic
instructions
64-kbyte address space; general register system; concise instruction set;
powerful bit manipulation instructions
Same CPU as the H8/300 Series; consumer application oriented supporting
modules; low voltage, low power consumption

H8/300L
This document gives an overview of the new H8S/2000 Series products with on-chip flash
memory (featuring single-power-supply programming): the 100-pin H8S/2148 Series and
H8S/2144 Series, and the 80-pin H8S/2138 Series and H8S/2134 Series.
Intended Readership:
This Overview is intended for readers who have a basic understanding of
microcomputers, and are looking for information on the features and functions of the H8S/2148,
H8S/2144, H8S/2138, and H8S/2134 Series. Readers undertaking system design using these
products, or requiring more detailed information on their use, should refer to the relevant Hardware
Manuals and the H8S/2600 and H8S/2000 Series Programming Manual.
