Keep safety first in your circuit designs!
1. Renesas Technology Corp. puts the maximum effort into making semiconductor products better and
more reliable, but there is always the possibility that trouble may occur with them. Trouble with
semiconductors may lead to personal injury, fire or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate
measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or
(iii) prevention against any malfunction or mishap.

algorithms represents information on products at the time of publication of these materials, and are
subject to change by Renesas Technology Corp. without notice due to product improvements or
other reasons. It is therefore recommended that customers contact Renesas Technology Corp. or
an authorized Renesas Technology Corp. product distributor for the latest product information before
purchasing a product listed herein.
The information described here may contain technical inaccuracies or typographical errors.
Renesas Technology Corp. assumes no responsibility for any damage, liability, or other loss rising
from these inaccuracies or errors.
Please also pay attention to information published by Renesas Technology Corp. by various means,
including the Renesas Technology Corp. Semiconductor home page (http://www.renesas.com).
4. When using any or all of the information contained in these materials, including product data,
diagrams, charts, programs, and algorithms, please be sure to evaluate all information as a total
system before making a final decision on the applicability of the information and products. Renesas
Technology Corp. assumes no responsibility for any damage, liability or other loss resulting from the

5. Renesas Technology Corp. semiconductors are not designed or manufactured for use in a device or
system that is used under circumstances in which human life is potentially at stake. Please contact
Renesas Technology Corp. or an authorized Renesas Technology Corp. product distributor when
considering the use of a product contained herein for any specific purposes, such as apparatus or
systems for transportation, vehicular, medical, aerospace, nuclear, or undersea repeater use.
6. The prior written approval of Renesas Technology Corp. is necessary to reprint or reproduce in
whole or in part these materials.
7. If these products or technologies are subject to the Japanese export control restrictions, they must
be exported under a license from the Japanese government and cannot be imported into a country
other than the approved destination.
Any diversion or reexport contrary to the export control laws and regulations of Japan and/or the
country of destination is prohibited.
8. Please contact Renesas Technology Corp. for further details on these materials or the products
contained therein.
General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are they are used as test
pins or to reduce noise. If something is connected to the NC pins, the operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins are in their open states,
intermediate levels are induced by noise in the vicinity, a pass-through current flows internally, and a malfunction
may occur.
3. Processing before Initialization
Note: When power is first supplied, the product’s state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the chip and a low level is
input on the reset pin. During the period where the states are undefined, the register settings and the output state
of each pin are also undefined. Design your system so that it does not malfunction because of processing while it
is in this undefined state. For those products which have a reset function, reset the LSI immediately after the
power supply has been turned on.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers may have been be allocated
to these addresses. Do not access these registers; the system’s operation is not guaranteed if they are accessed.
Preface
This LSI is a single-chip microcomputer with a 32-bit H8S/2000 CPU core, and a set of on-chip peripheral functions
required for system configuration.
This LSI is equipped with ROM, RAM, a bus controller, a data transfer controller (DTC), a programmable pulse generator
(PPG), three types of timers, a serial communication interface (SCI), a D/A converter, an A/D converter, and I/O ports as
on-chip peripheral functions. This LSI is suitable for use as an embedded microcomputer for high-level control systems.
Its on-chip ROM is flash memory (F-ZTAT
TM
*), PROM (ZTAT
®
*), or masked ROM that 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/2357 Group in the design of application
systems. Members of this audience 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/2357
Group to the above audience.
Refer to the H8S/2600 Series, H8S/2000 Series Programming Manual for a detailed description of the
instruction set.
Notes on reading this manual:
•
