Description The CXP853P40A are a highly integrated microcomputers composed of a 8-bit CPU, PROM, RAM, and I/O ports. These chips feature many other highperformance circuits in a single-chip CMOS design, including an A/D converter, serial interface, timer/counter, time-base timer, vector interrupt, onscreen display function, I2C bus interface, PWM generator, remote control receiver, HSYNC counter, power supply frequency counter, and watchdog timer. Features • A wide instruction set (213 instructions) which covers various of data — 16-bit arithmetic instruction/multiplication and division instructions/boolean bit operation instruction • Minimum instruction cycle 1µs/4MHz (4MHz verison) 0.5µs/8MHz (8MHz verison) • Incorporated PROM capacity 40K bytes (For program) 6.75K bytes (For OSD) • Incorporated RAM capacity 576 bytes • Peripheral funcitons — On-screen display function 12 × 18 dots, 256 types, 15 colors, 12 lines of 21 characters Black frame output half blanking, shadow, background color on full screen/half blanking Double scanning mode supported, jitter elimination circuit — I2C bus interface — PWM output 14 bits, 1 channel 8 bits, 8 channels — Remote control receiver circuit 8-bit pulse measuring counter, 6-stage FIFO — A/D converter 8-bit, 4 channels, successive approximation system (conversion time of 40µs/4MHz, 8MHz) — HSYNC counter — Power supply frequency counter — Watchdog timer — Serial I/O 8-bit synchronized — Timer 8-bit timer, 8-bit timer/counter, 19-bit time-base timer • Interruption 14 factors, 14 vectors, multiple interrupt possible • Standby mode Sleep • Package 64-pin plastic SDIP/QFP
