Overview

Features

This LSI is a single-chip RISC (Reduced Instruction Set Computer) microcomputer that integrates a Renesas Technology original RISC CPU core with peripheral functions required for system configuration.

The CPU in this LSI 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, he 32-bit internal-bus architecture enhances data processing power. With this CPU, it has become possible to assemble low-cost, high-performance, and high-functioning systems, even for applications that were previously impossible with microcomputers, such as real-time control, which demands high speeds.

In addition, this LSI includes on-chip peripheral functions necessary for system configuration, such as large-capacity ROM and RAM, a data transfer controller (DTC), timers, a serial communication interface (SCI), a synchronous serial communication unit, an A/D converter, an nterrupt controller (INTC), I/O ports, and controller area network (RCAN-ET).

This LSI also provides an external memory access support function to enable direct connection to various memory devices or peripheral LSIs. These on-chip functions significantly reduce costs of designing and manufacturing application systems.

The version of on-chip ROM is F-ZTATTM (Flexible Zero Turn Around Time)* that includes flash memory. The flash memory can be programmed with a programmer that supports programming of his LSI, and can also be programmed and erased by software. This enables LSI chip to be reprogrammed at a user-site while mounted on a board.

The features of this LSI are listed in table 1.1.Overview
