Section 1 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.

In addition, the SH7108 Series includes on-chip peripheral functions necessary for system

configuration, such as ROM, RAM, timers, a serial communication interface (SCI), an A/D

converter, an interrupt controller (INTC), and I/O ports.

As the on-chip ROM, only masked ROM version is available. However, when F-ZTAT (Flexible

Zero Turn Around Time) version is required, the SH7046F (80 pins) or SH7047F (100 pins) can

be used.
