Cautions
Keep safety first in your circuit designs!
1.
Renesas Technology Corporation puts the maximum effort into making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or
property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i) placement
of substitutive, auxiliary circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or mishap.

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.
