Overview
The H8S/2199 Series comprise microcomputers (MCUs) built around the H8S/2000 CPU,
employing Hitachi's proprietary architecture, and equipped with supporting modules on-chip.
The H8S/2000 has an internal 32-bit architecture, is provided with sixteen 16-bit general registers
and a concise, optimized instruction set designed for high-speed operation, and can address a 16-
Mbyte linear address space. The instruction set is upward-compatible with H8/300 and H8/300H
CPU instructions at the object-code level, facilitating migration from the H8/300, H8/300L, or
H8/300H Series.
The H8S/2199 Series is equipped with a digital servo circuit, sync separator, OSD, data slicer,
ROM, RAM, seven types of timers, three types of PWM, two types of serial communication
interface, an I
2
C bus interface, A/D converter, and I/O port as on-chip supporting modules.
The on-chip ROM is either flash memory (F-ZTAT
*) or mask ROM, with a capacity of 128,
112, 96, or 80 kbytes. ROM is connected to the CPU via a 16-bit data bus, enabling both byte and
word data to be accessed in one state. Instruction fetching has been speeded up, and processing
speed increased.
The features of the H8S/2199 Series are shown in table 1.1.
