Cautions
1. Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s
patent, copyright, trademark, or other intellectual property rights for information contained in
this document. Hitachi bears no responsibility for problems that may arise with third party’s
rights, including intellectual property rights, in connection with use of the information
contained in this document.
2. Products and product specifications may be subject to change without notice. Confirm that you
have received the latest product standards or specifications before final design, purchase or
use.
3. Hitachi makes every attempt to ensure that its products are of high quality and reliability.
However, contact Hitachi’s sales office before using the product in an application that
demands especially high quality and reliability or where its failure or malfunction may directly
threaten human life or cause risk of bodily injury, such as aerospace, aeronautics, nuclear
power, combustion control, transportation, traffic, safety equipment or medical equipment for
life support.
4. Design your application so that the product is used within the ranges guaranteed by Hitachi
particularly for maximum rating, operating supply voltage range, heat radiation characteristics,
installation conditions and other characteristics. Hitachi bears no responsibility for failure or
damage when used beyond the guaranteed ranges. Even within the guaranteed ranges,
consider normally foreseeable failure rates or failure modes in semiconductor devices and
employ systemic measures such as fail-safes, so that the equipment incorporating Hitachi
product does not cause bodily injury, fire or other consequential damage due to operation of
the Hitachi product.
5. This product is not designed to be radiation resistant.
6. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document
without written approval from Hitachi.
7. Contact Hitachi’s sales office for any questions regarding this document or Hitachi
semiconductor products.

General Precautions on the Handling of Products
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are not connected to any of the internal circuitry; 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
The SH7144 Series single-chip RISC (Reduced Instruction Set Computer) microprocessor
includes a Hitachi-original RISC CPU as its core, and the peripheral functions required to
configure a system.
Target users: This manual was written for users who will be using this LSI in the design of
application systems. Users of this manual 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 this LSI to the above users.
Refer to the SH-1, SH-2, SH-DSP Programming Manual for a detailed description
of the instruction set.

In this manual, the product abbreviations are used to distinguish products. For example, 112-
pin products are collectively referred to as the SH7144, an abbreviation of the basic type's
classification code, while 144-pin products are collectively referred to as the SH7145. There
are two versions of each: a flash memory version and a mask ROM version. When a
description is limited to the flash memory version alone, the character F is added at the end of
the abbreviation, such as SH7144F. When a description is limited to the mask ROM version
alone, an abbreviation that is determined by adding M at the end of the abbreviation.
