Preface
The H8S/2000 Series is a new series of Hitachi-original high-performance 16-bit microcomputers
designed to offer higher performance and lower power consumption than existing H8 Series
models, which are widely used in equipment control, and provide much greater ease of use. These
microcomputers include a CPU, RAM, ROM, DMA controller, data transfer controller, bus
controller, timers, SCI, A/D converter, and other on-chip supporting modules, making them
suitable for use in a wide range of applications from small to large-scale systems. Another major
feature of the H8S/2000 Series is upward-compatibility at the CPU object code level with the
H8/300H, H8/300, and H8/300L Series within the H8 Series, allowing the use of existing software
resources.
This Microcomputer Technical Q&A Application Note covers the H8S/2655 Series, H8S/2350
Series, H8S/2355 Series, H8S/2357, H8S/2345 Series, H8S/2245 Series, H8S/2148 Series,
H8S/2144 Series, H8S/2138 Series, H8S/2134 Series, H8S/2128 Series, and H8S/2124 Series.
