Section 1 Overview
This LSI is a single-chip RISC microprocessor that integrates a Renesas Technology original 32-
bit SuperH RISC engine architecture CPU with a digital signal processing (DSP) extension as its
core, with 16-kbyte of cache memory, 16-kbyte of an on-chip X/Y memory, and peripheral
functions required for system configuration such as an interrupt controller. This LSI comes in 256-
pin package.
High-speed data transfers can be formed by an on-chip direct memory access controller (DMAC),
and an external memory access support function enables direct connection to different kinds of
memory. This LSI also supports powerful peripheral functions such as USB function and serial
communication interface with FIFO.
1.1 Features
The features of this LSI are listed in table 1.1.
