• Manufacturer: Hitachi

Preface
The H8S/2626 Series and H8S/2623 Series are series of high-performance microcontrollers with a
32-bit H8S/2600 CPU core, and a set of on-chip supporting modules 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 mask 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.
On-chip supporting functions include a 16-bit timer pulse unit (TPU), programmable pulse
generator (PPG), watchdog timer (WDT), serial communication interface (SCI), Hitachi controller
area network (HCAN), A/D converter, D/A converter (H8S/2626 Series only), and I/O ports.
In addition, data transfer controller (DTC) is provided, enabling high-speed data transfer without
CPU intervention.
Use of the H8S/2626 Series or H8S/2623 Series enables easy implementation of compact, high-
performance systems capable of processing large volumes of data.
This manual describes the hardware of the H8S/2626 Series and H8S/2623 Series. Refer to the
H8S/2600 Series and H8S/2000 Series Programming Manual for a detailed description of the
instruction set.
