Sony CXP922P032 Datasheet

Description

The CXP922P032 is a CMOS 16-bit microcomputer
integrating on a single chip an A/D converter, serial
interface, timer, remote control receive circuit, PWM
output circuit, and as well as basic configurations like a
16-bit CPU, PROM, RAM, and I/O port.

This LSI also provides the sleep/stop functions that

enable lower power consumption.

The CXP922P032 is the PROM-incorporated
version of the CXP922032 with built-in mask ROM.
This provides the additional feature of being able to
write directly into the program. Thus, it is most
suitable for evaluation use during system
development and for small-quantity production.

Features

• Minimum instruction cycle 100ns/20MHz operation (3.0 to 5.5V)

167ns/12MHz operation (2.7 to 5.5V)

• Incorporated PROM capacity 128K bytes

• Incorporated RAM capacity 7680 bytes

• Peripheral functions

— A/D converter

(Conversion time:

12.4µs at 20MHz)

— Serial interface Asynchronous serial interface (Simple UART)

128-byte buffer RAM,3 channels

— Timers 8-bit timer/counter, 2 channels (with timing output)

16-bit capture timer/counter (with timing output)

16-bit timer, 4 channels
— Remote control receive circuit 8-bit pulse measurement counter, 8-stage FIFO
— PWM output circuit 14-bit, 1 channel

• Interruption 24 factors, 24 vectors, multi-interruption and priority selection possible

• Standby mode Sleep/stop
