anti-crime systems; and safety equipment etc.
Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct threat to
human life or bodily injury (artificial life support devices or systems, surgical implantations etc.), or may cause serious property
damages (nuclear reactor control systems, military equipment etc.). You must check the quality grade of each Renesas
Electronics product before using it in a particular application. You may not use any Renesas Electronics product for any
application for which it is not intended. Renesas Electronics shall not be in any way liable for any damages or losses incurred
by you or third parties arising from the use of any Renesas Electronics product for which the product is not intended by Renesas
Electronics.

You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,
especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation
characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or
damages arising out of the use of Renesas Electronics products beyond such specified ranges.
Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have
specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further,
Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to
guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas
Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire control and
malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the
evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or systems
manufactured by you.
Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental compatibility
of each Renesas Electronics product. Please use Renesas Electronics products in compliance with all applicable laws and
regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive.
Renesas Electronics assumes no liability for damages or losses occurring as a result of your noncompliance with applicable laws
and regulations.
Renesas Electronics products and technology may not be used for or incorporated into any products or systems whose
manufacture, use, or sale is prohibited under any applicable domestic or foreign laws or regulations. You should not use
Renesas Electronics products or technology described in this document for any purpose relating to military applications or use
by the military, including but not limited to the development of weapons of mass destruction. When exporting the Renesas
Electronics products or technology described in this document, you should comply with the applicable export control laws and
regulations and follow the procedures required by such laws and regulations.

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.
5. Reading from/Writing to Reserved Bit of Each Register
Note: Treat the reserved bit of register used in each module as follows except in cases where the
specifications for values which are read from or written to the bit are provided in the
description.
The bit is always read as 0. The write value should be 0 or one, which has been read
immediately before writing.
Writing the value, which has been read immediately before writing has the advantage of
preventing the bit from being affected on its extended function when the function is
assigned.

Preface
The SH-4 (SH7750 Group: SH7750, SH7750S, SH7750R) microprocessor incorporates the 32-bit
SH-4 CPU and is also equipped with peripheral functions necessary for configuring a user system.
The SH7750 Group is built in with a variety of peripheral functions such as cache memory,
memory management unit (MMU), interrupt controller, timers, two serial communication
interfaces (SCI, SCIF), real-tim1e clock (RTC), user break controller (UBC), bus state controller
(BSC) and smart card interface. This LSI can be used in a wide range of multimedia equipment.
The bus controller is compatible with ROM, SRAM, DRAM, synchronous DRAM and PCMCIA,
as well as 64-bit synchronous DRAM 4-bank system and 64-bit data bus.
Target Readers:
This manual is designed for use by people who design application systems using
the SH7750, SH7750S, or SH7750R.
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 SH7750, SH7750S, and SH7750R.
The SH-4 Software Manual contains detailed information of executable instructions. Please read
the Software 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.
•
