CXP825P40 CMOS 8-bit Single Chip Microcomputer Description The CXP825P40 is a highly integrated CMOS 8-bit single chip microcomputer which is mainly composed of an 8-bit CPU, PROM, RAM, and I/O ports. This microcomputer features many other high-performance circuits in a single chip CMOS design, including an A/D converter, serial interface, timer/counter, timebase timer, capture timer/counter, fluorescent display tube controller/driver, remote control receiver. Also, the CXP825P40 provides the power-on reset function as well as the sleep/stop function which assures reduced power consumption. Being a PROM-incorporated version of the CXP82540 which has on-chip mask ROM, the CXP825P40 permits program writing. Therefore, it is ideally suited for use in system development stage evaluation and job lot procuction. 80 pin QFP (Plastic) Structure Silicon gate CMOS IC Features • Instruction set which supports a wide array of data types 213 types — 16-bit arithmetic instruction/multiplication and division instructions/boolean bit operation instruction • Minimum instruction cycle During operation 400ns/10MHz • Incorporated PROM capacity 40K bytes • Incorporated RAM capacity 1120 bytes (Including the fluorescent display data area) • Peripheral functions — A/D converter 8-bit, 8-channel, successive comparison type (conversion time: 32µs at 10MHz) — Serial interface 1-channel data interface with an 8-bit, 8-stage FIFO (1 to 8 bytes automatic transfer) 1 channel, 8-bit clock synchronized interface — Timers 8-bit timer 8-bit timer/counter 19-bit time-base timer 16-bit capture timer/counter — Fluorescent display tube controller/driver Display of up to 336 segments 1 to 16 digits dynamic display Dimmer function High voltage tolerance output (40V) Built-in pull-down resistor — Remote control receiver Built-in noise suppressor circuit Built-in 8-bit pulse counter and 6-stage FIFO • Interrupts 14 factors, 15 vectors, multiple interrupt processing • Standby mode Sleep/stop • Package 80-pin plastic QFP Sony reserves the right to change products and specifications without prior notice.
