CXP822P24

CXP822P24 CMOS 8-bit Single Chip Microcomputer Description The CXP822P24 is a CMOS 8-bit single chip microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, capture timer counter, fluorescent display tube controller/driver, remote control reception circuit, CTL duty detection circuit, 14-bit PWM output and highspeed output circuit besides the basic configurations of 8-bit CPU, PROM, RAM, and I/O port. The CXP822P24 also provides sleep/stop function that enables lower power consumption. CXP822P24 is the PROM-incorporated version of the CXP82224 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 smallquantity producton. 100 pin QFP (Plastic) Structure Silicon gate CMOS IC Features Wide-range instruction system (213 instructions) to cover various types of data. — 16-bit arithmetic/multiplication and division/Boolean bit operation instructions Minimum instruction cycle 400ns at 10MHz operation 122µs at 32kHz operation Incorporated PROM capacity 24K bytes Incorporated RAM capacity 704 bytes (including fluorescent display area) Peripheral functions — A/D converter 8-bit, 8-channel, successive approximation method (Conversion time of 32µs/10MHz) — Serial interface SIO with 8-bit, 8-stage FIFO incorporated for data use (Auto transfer for 1 to 8 bytes), 1 channel 8-bit standard SIO,...
