Section 1 Overview

This LSI is a CMOS single-chip microcontroller that integrates a Renesas Technology original

RISC (Reduced Instruction Set Computer) CPU core with peripheral functions required for an

Ethernet system.

The CPU of this LSI has a RISC (Reduced Instruction Set Computer) type instruction set. The

CPU basically operates at a rate of one instruction per cycle, offering a great improvement in

instruction execution speed. In addition, the 32-bit internal architecture provides improved data

processing power. With this CPU, it has become possible to assemble low-cost and high-

performance/high-functionality systems even for applications such as realtime control, which

could not previously be handled by microcontrollers because of their high-speed processing

requirements.

This LSI is equipped with an Ethernet controller that includes a media access controller (MAC)

conforming to the IEEE802.3u standard and a physical layer transceiver (PHY), enabling 10/100

Mbps LAN connection. As the equipped Ethernet controller also includes a media independent

interface (MII) standard unit, a PHY LSI can be externally connected.

In addition, this LSI provides on-chip peripheral functions necessary for system configuration,

such as cache memory, RAM, a direct memory access controller (DMAC), timers, a serial

communication interface with FIFO (SCIF), a serial IO with FIFO (SIOF), a host interface (HFI),

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

The external memory access support function of this LSI enables direct connection to various

types of memory, such as standard memory, SDRAM, and PCMCIA. This greatly reduces system

cost.
