SH7286, SH7285, and SH7243 Features

This LSI is a single-chip RISC microprocessor 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 (Reduced Instruction Set Computer) instruction set and uses

a superscalar architecture and a Harvard architecture, 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, and high-

functioning systems, even for applications that were previously impossible with microprocessors,

such as realtime control, which demands high speeds.

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

such as a large-capacity ROM, a ROM cache, a RAM, a direct memory access controller

(DMAC), a data transfer controller (DTC), multi-function timer pulse units 2 (MTU2 and

MTU2S), a serial communication interface with FIFO (SCIF), a serial communication interface

(SCI), a synchronous serial communication interface (SSU), an A/D converter, a D/A converter,

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

2C bus interface 3 (IIC3), a universal serial bus (USB),

and a 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 features of this LSI are listed in table 1.1.
