Preface - Hitachi H8S/2628 Hardware Manual

The H8S/2628 Series are single-chip microcomputers made up of the high-speed H8S/2600 CPU
as its core, and the peripheral functions required to configure a system. The H8S/2600 CPU has an
instruction set that is compatible with the H8/300 and H8/300H CPUs.
This LSI is equipped with a data transfer controller (DTC), ROM and RAM memory, a PC break
controller (PBC), a 16-bit timer pulse unit (TPU), a programmable pulse generator (PPG), a
watchdog timer (WDT), a serial communication interface (SCI), a Hitachi controller area network
(HCAN), a synchronous serial communication unit (SSU), an A/D converter, and I/O ports as on-
chip peripheral modules required for system configuration. This LSI is suitable for use as an
embedded microcomputer for high-level control systems. A single-power flash memory (F-
ZTAT TM ) version is available for this LSI's ROM. This provides flexibility as it can be
reprogrammed in no time to cope with all situations from the early stages of mass production to
full-scale mass production. This is particularly applicable to application devices with
specifications that will most probably change.

Target Users: This manual was written for users who will be using the H8S/2628 Series in the
design of application systems. Target users are expected to understand the
fundamentals of electrical circuits, logical circuits, and microcomputers.
Objective: This manual was written to explain the hardware functions and electrical
characteristics of the H8S/2628 Series to the target users.
Refer to the H8S/2600 Series Programming Manual for a detailed description of
the instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
Read the manual according to the contents. This manual can be roughly categorized into parts
on the CPU, system control functions, peripheral functions and electrical characteristics.
• In order to understand the details of the CPU's functions
Read the H8/300H Series Programming Manual.
• In order to understand the details of a register when its name is known
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 22,
List of Registers.
