Section 1 Overview
1.1 Features
The SH7729R is a single-chip RISC microprocessor that integrates a 32-bit RISC-type SuperH
RISC engine architecture CPU with a digital signal processing (DSP) extension as its core,
together with cache memory, an on-chip X/Y 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. The SH7729R includes data
protection, virtual memory, and other functions provided by incorporating an MMU, into a
SuperH Series microprocessor (SH-1 or SH-2). The provision of on-chip DSP functions enables
applications that previously required the use of two chips—a microprocessor and a DSP—to be
implemented with a single chip.
The SH7729R chip has the same peripheral modules as the SH7729. 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. The SH7729R
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 high-
speed operation. The SH7729R can run at six times the system bus operating speed, making it also
ideal for devices such as PDAs that require both high speed and low power consumption.
The features of the SH7729R are listed in table 1.1.
