Preface
The SH-4 (SH7751 Series (SH7751, SH7751R)) microprocessor incorporates the 32-bit SH-4
CPU and is also equipped with peripheral functions necessary for configuring a user system.
The SH7751 Series is built in with a variety of peripheral functions such as cache memory,
memory management unit (MMU), interrupt controller, floating-point unit (FPU), timers, two
serial communication interfaces (SCI, SCIF), real-time clock (RTC), user break controller (UBC),
bus state controller (BSC) and PCI controller (PCIC). This series can be used in a wide range of
multimedia equipment. The bus controller is compatible with ROM, SRAM, DRAM, synchronous
DRAM and PCMCIA.
Target Readers: This manual is designed for use by people who design application systems using
the SH7751 or SH7751R.
To use this manual, basic knowledge of electric circuits, logic circuits and microcomputers is
required.
This hardware manual contains revisions related to the addition of R-mask functionality. Be sure
to check the text for the updated content.
Purpose: This manual provides the information of the hardware functions and electrical
characteristics of the SH7751 and SH7751R.
The SH-4 Programming Manual contains detailed information of executable instructions. Please
read the Programming Manual together with this manual.
