Features

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 incorporated in this LSI is the SH-2A CPU, which features upward compatibility on the

object code level with the SH-1 and SH-2 microcomputers. The CPU has a RISC-type instruction

set and employs a superscalar architecture and the Harvard architecture, which greatly improves

instruction execution speed. In addition, the 32-bit internal-bus architecture enhances data

processing power. This CPU realizes low-cost, high-performance, and high-functioning systems

for applications such as high-speed realtime control, which was previously impossible with the

conventional microcomputers.

This LSI includes an Ethernet controller (EtherC) that incorporates a media access controller

(MAC) conforming to the IEEE802.3u standard, which offers the LAN connection in the rate of

10 or 100Mbps.

In addition, this LSI includes on-chip peripheral functions required for systems, such as, cache

memory, RAM, a direct memory access controller (DMAC), a host interface (HIF), an USB2.0

host/function module (USB), an SD host interface (SDHI), an interrupt controller (INTC), a

compare match timer (CMT), a serial communication interface with FIFO (SCIF), and I/O ports.

Moreover, this LSI includes encryption functions (AES, DES and 3DES), message authentication

code generating functions (HMAC-SHA-1, HMAC-SHA-224, and HMAC-SHA-256), an AV

stream interface (STIF), and a serial sound interface (SSI), which can be applied to digital AV

equipment with network features.

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.
