Overview

Features of This LSI

This LSI is a single-chip RISC microprocessor that integrates a 32-bit RISC-type SuperH architecture CPU as its core with a floating point unit (FPU), 64-Kbyte large-capacity cache memory, 16-Kbyte on-chip memory, an interrupt controller, and other peripherals.

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 kinds of memory.

Moreover, this LSI incorporates a 16-bit timer pulse unit (TPU), realtime clock (RTC), compare match timer (CMT), stereo audio recording/playback function interface (SIOF), I2C bus interface (IIC), serial communication interface with FIFO (SCIF), IrDA interface (IrDA), SIM card interface (SIM), A/D converter (ADC), and D/A converter (DAC).

A powerful built-in power-management function keeps power consumption low, even during high-speed operation. This LSI is ideal for use in electronic devices such as those for applications that require both high-speed operation and low power consumption simultaneously.
