CXP844P16 CMOS 8-bit Single Chip Microcomputer Description The CXP844P16 is a CMOS 8-bit single chip microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, 32kHz timer/counter, remote control reception circuit and other servo systems besides the basic configurations of 8-bit CPU, PROM, RAM, and I/O port. The CXP844P16 also provides and a sleep/stop function that enables lower power consumption. This IC is the PROM-incorporated version of the CXP84416 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 production. 80 pin QFP (PIastic) 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 16Kbytes • Incorporated RAM capacity 448bytes • Peripheral functions — A/D converter 8-bit, 8-channel, successive approximation method (Conversion time of 32µs/10MHz) — Serial interface Incorporated 8-bit, 8-stage FIFO (Auto transfer for 1 to 8 bytes), 2 channel — Timer 8-bit timer, 8-bit timer/counter, 19-bit time base timer, 32kHz timer/counter — Remote control reception circuit Incorporated 6-stage FIFO 8-bit measurement counter — PWM output for tuner 14 bits, 1 channel • Interruption 12 factors, 12 vectors, multi-interruption possible • Standby mode SLEEP/STOP • Package 80-pin plastic QFP Structure Silicon gate CMOS IC Sony reserves the right to change products and specifications without prior notice.
