Description The CXP82532/82540 microcomputer is composed of a CPU, ROM RAM, and I/O ports. These chips feature many other high-performance circuits in a single-chip CMOS design, including an A/D converter, serial interface, timer/counter, time-base timer, capture timer/counter, fluorescent display controller/driver, remote control receiver. This device also includes a power-on reset function and sleep/stop functions which can be used to achieve low power consumption. Features • Instruction set which supports a wide array of data types — 213 types of instructions which include 16-bit calculations, multiplication and division arithmetic, and boolean bit operations. • Minimum instruction cycle 400ns for 10MHz operation • On-chip ROM 32K bytes (CXP82532) 40K bytes (CXP82540) • On-chip RAM 1120 bytes (Including fluorescent display data area) • Peripheral functions: — A/D converter 8-bit, 8-channel, successive approximation system (conversion time 32µs/10MHz) — Serial interface On-chip 8-bit, 8-stage FIFO (1 to 8 bytes auto transfer) 1 channel 8-bit clock synchronized 1 channel — Timers 8-bit timer 8-bit timer/counter 19-bit time-base timer 16-bit capture timer/counter — Fluorescent display controller/driver Maximum of 336 segment display available 1 to 16 digits dynamic display Dimmer function High voltage tolerance output (40V) On-chip pull-down resistor (Mask option) — Remote control receiver circuit On-chip noise elimination circuit On-chip 6 stage FIFO 8-bit pulse measurement counter • Interrupts 14 factors, 15 vectors multi-interruption possible • Standby mode Sleep/stop • Package 80-pin plastic QFP • Piggyback/evaluator CXP82500 80-pin ceramic QFP
