Preface

The H8S/2643 Group is a group of high-performance microcontrollers with a 32-bit H8S/2600 CPU core, and a set of on-chip supporting functions required for system configuration.

The H8S/2600 CPU can execute basic instructions in one state, and is provided with sixteen 16-bit general registers with a 32-bit internal configuration, and a concise and optimized instruction set. The CPU can handle a 16 Mbyte linear address space (architecturally 4 Gbytes). Programs based on the high-level language C can also be run efficiently.

The address space is divided into eight areas. The data bus width and access states can be selected for each of these areas, and various kinds of memory can be connected fast and easily.

Single-power-supply flash memory (F-ZTAT™*) and masked ROM versions are available, providing a quick and flexible response to conditions from ramp-up through full-scale volume production, even for applications with frequently changing specifications.
