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.
Notes regarding these materials
1. These materials are intended as a reference to assist our customers in the selection of the Renesas
Technology Corp. product best suited to the customer's application; they do not convey any license
under any intellectual property rights, or any other rights, belonging to Renesas Technology Corp. or
a third party.
2. Renesas Technology Corp. assumes no responsibility for any damage, or infringement of any third-
party's rights, originating in the use of any product data, diagrams, charts, programs, algorithms, or
circuit application examples contained in these materials.

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
information contained herein.
5. Renesas Technology Corp. semiconductors are not designed or manufactured for use in a device or

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
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
The H8S/2558 Group, H8S/2239 Group, H8S/2238 Group, H8S/2237 Group, and H8S/2227
Group are high-performance microcomputers made up of the internal 32-bit configuration
H8S/2000 CPU as their cores, and the peripheral functions required to configure a system.
A single-power flash memory (F-ZTAT
TM
*) version and masked ROM version are available for
these LSIs’ ROM. These versions provide flexibility as they 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 of which the specifications frequently
changeable.
On-chip peripheral functions of each microcomputer are summarized below.
Note: * F-ZTAT is a trademark of Renesas Technology Corp.
