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 address
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 address. Do not access these registers: the system’s
operation is not guaranteed if they are accessed.

Preface
The SH7727 microprocessor incorporates the 32-bit SH-3 CPU and is also equipped with
peripheral functions necessary for configuring a user system.
The SH7727 is built in with a variety of peripheral functions such as cache memory, memory
management unit (MMU), interrupt controller, timers, three serial communication interfaces (SCI,
SCIF, SIOF), real-time clock (RTC), user break controller (UBC), bus state controller (BSC) and
AFE interface. The SH7727 can be used in a variety of applications that demand a high-speed
microcomputer with low power consumption.
The descriptions in this manual are based on the SH7727B. For details on using versions previous
to the SH7727B please refer to Using Versions Previous to the SH7727B at the end of the manual.
Note that the version is the SH7727B if “B” is engraved on the chip. If there is no such indication
the product is a version previous to the SH7727B. (See section xx-xx.)
Target Readers:
This manual is designed for use by people who design application systems using
the SH7727.
To use this manual, basic knowledge of electric circuits, logic circuits and microcomputers is
required.
Purpose:
This manual provides the information of the hardware functions and electrical
characteristics of the SH7727.
The SH-3, SH-3E, SH3-DSP Programming Manual contains detailed information of executable
instructions. Please read the Programming Manual together with this manual.
How to Use the Book:
•
To understand general functions
→
Read the manual from the beginning.
The manual explains the CPU, system control functions, peripheral functions and electrical
characteristics in that order.
•
To understanding CPU functions
→
Refer to the separate SH-3, SH-3E, SH3-DSP Programming Manual.
