SH7709S

This LSI is a single-chip RISC microprocessor that integrates a Hitachi-original RISC-type SuperHTM* architecture CPU as its core that has an on-chip multiplier, cache memory, and a memory management unit (MMU) as well as peripheral functions required for system configuration such as a timer, a realtime clock, an interrupt controller, and a serial communication interface. This LSI includes data protection, virtual memory, and other functions provided by incorporating an MMU into a SuperH series microprocessor (SH-1 or SH-2).

High-speed data transfers can be performed by an on-chip direct memory access controller (DMAC) and an external memory access support function enables direct connection to different types of memory. The SH7709S microprocessor also supports an infrared communication function, an A/D converter, and a D/A converter.

A powerful built-in power management function keeps power consumption low, even during highspeed operation. This LSI can run at six times the frequency of the system bus operating speed, making it optimum for electrical devices such as PDAs that require both high speed and low power.

The features of this LSI is listed in table 1.1. The specifications are shown in table 1.2.
