Preface

The SH7040 Series (SH7040, SH7041, SH7042, SH7043, SH7044, SH7045) single-chip RISC

(Reduced Instruction Set Computer) microprocessors integrate a Renesas Technology-original

RISC CPU core with peripheral functions required for system configuration.

The CPU has a RISC-type instruction set

. Most instructions can be executed in one clock cycle,

which greatly improves instruction execution speed

. In addition, the 32-bit internal-bus

architecture enhances data processing power. With this CPU, it has become possible to assemble

low cost, high performance/high-functioning systems, even for applications that were previously

impossible with microprocessors, such as real-time control, which demands high speeds. In

particular, the SH7040 series has a 1-kbyte on-chip cache, which allows an improvement in CPU

performance during external memory access.

In addition, the SH7040 series includes on-chip peripheral functions necessary for system

configuration, such as large-capacity ROM and RAM, timers, a serial communication interface

(SCI), an A/D converter, an interrupt controller, and I/O ports. Memory or peripheral LSIs can be

connected efficiently with an external memory access support function. This greatly reduces

system cost.

There are versions of on-chip ROM: mask ROM, PROM, and flash memory. The flash memory

can be programmed with a programmer that supports SH7040 series programming, and can also

be programmed and erased by software.

This hardware manual describes the SH7040 series hardware. Refer to the programming manual

for a detailed description of the instruction set.
