Product Summary
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.
