Preface
This LSI is a microprocessor wi th the 32- bit SH-3 CPU as its core and peripheral functions
necessary for configuring a user system.
This LSI is built in with a variety of peripheral functions such as cache memory, memory
management unit (MMU), interrupt controller, timer, three serial communication interfaces, real-
time clock (RTC), use break c ontroller (UBC), bus state controller (BSC) and I/O ports.
This LSI can be used as a microcomputer for devices that require both high speed and low power
consumption.
Target Readers: This manual is designed for use by people who design application systems using
the SH7709S.
To use this manual, basic knowledge of electric circuits, logic circuits and microcomp u ters is
required.
Purpose: This manual provides the information of the hard ware functions and electrical
characteris t ics of the SH7709S.
The SH3, SH-3E, SH3-DSP Programming Manual contains detailed informati on 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 SH3, SH-3E, SH3 -D SP Programming Manual.
Explanatory Note: Bit sequence: upper bit at left, and lower bit at right
