Preface
This LSI is a microprocessor with 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 controller (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 microcomputers is
required.
Purpose: This manual provides the information of the hardware functions and electrical
characteristics of the SH7709S.
The SH3, SH-3E, SH3-DSP Programming Manual contains detailed information of executable
instructions. Please read the Programming Manual together with this manual.
