CMOS 32-bit Single Chip Microcomputer
Description
The CXR704060 is a CMOS 32-bit microcomputer
integrating on a single chip a micro processor unit
having a 32-bit RISC CPU as its core, and a signal
processing block having an accelerator circuit suited
for arithmetic signal processing. Adoption of this
arithmetic signal processing accelerator circuit
enables flexible support of various signal processing
systems.
The microcomputer block incorporates Memory Stick
interface, a MagicGate, FLASH memory interface,
USB interface, D/A converter for audio applications,
A/D converter, serial interface, I
2
C bus interface,
timer and PWM pulse generator as well as basic
configurations like a 32-bit RISC CPU, ROM, RAM,
and I/O ports. It also provides the idle/sleep/stop
functions that enable lower power consumption.
