1 / 25 page CMOS 8-bit Single Chip Microcomputer Description The CXP87532/87540 is a CMOS 8-bit micro- computer which consists of arithmetic coprocessor, A/D converter, serial interface, timer/counter, time base timer, vector interruption, high precision timing pattern generation circuit, PWM generator and the measuring circuit which measures signals of capstan FG, drum FG/PG, reel FG and other servo systems, as well as basic configurations like 8-bit CPU, ROM, RAM and I/O port. They are integrated into a single chip. Also this IC provides power on reset function, sleep/stop function which enables to lower power consumption. Features • A wide instruction set (213 instructions) which covers various types of data — 16-bit operation multiplycation and division/boolean bit operation instructions • Minimum instruction cycle During operation 326ns/12.288MHz • Incorporated ROM capacity 32K bytes (CXP87532) 40K bytes (CXP87540) • Incorporated RAM capacity 1344 bytes • Peripheral functions — Arithmetic coprocessor Multiplying with code, sum of products with code, high speed execution of many bits shift rotation operation — A/D converter 8-bit, 8-channel, successive approximation system (Conversion time 13µs/12.288MHz) Incorporated 3-stage FIFO for A/D conversion data — Serial interface Incorporated buffer RAM for data (1 to 128 bytes auto transfer) 2-channel — Timer 8-bit timer, 8-bit timer/counter, 19-bit time base timer — High precision timing pattern generator PPG (11 pins) 32-stage programmable — PWM output 12-bit, 2-channel (Repeated frequency 48kHz) 8-bit, 3-channel (Repeated frequency 48kHz) — Servo input control Capstan FG, Drum FG/PG, Reel FG input — FRC capture unit Incorporated 28-bit and 8-stage FIFO • Interruption 12 factors, 12 vectors, multi-interruption possible • Standby mode Sleep/stop • Package 100-pin plastic QFP/LQFP • Piggyback/Evaluation CXP87500 100-pin ceramic QFP/LQFP Structure Silicon gate CMOS IC – 1 – E93820A81-PS Sony reserves the right to change products and specifications without prior notice.
