Overview

The SH7108 Series single-chip RISC microprocessor integrates a Renesas Technology original RISC CPU core with peripheral functions required for system configuration.

The SH7108 Series CPU has a RISC-type instruction set. Most instructions can be executed in one state (one system 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 realtime control, which demands high speeds.
