Overview

The SH7047 group single-chip RISC (Reduced Instruction Set Computer) microprocessors integrate a Renesas-original RISC CPU core with peripheral functions required for system configuration.

The SH7047 group 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 real-time control, which demands high speeds.

In addition, the SH7047 group includes on-chip peripheral functions necessary for system configuration, such as large-capacity ROM and RAM, timers, a serial communication interface (SCI), Controller area network 2 (HCAN2), an A/D converter, an interrupt controller (INTC), and I/O ports. ROM and SRAM can be directly connected to the SH7047 MCU by means of an external memory access support function. This greatly reduces system cost.
