CXP853P40A

CXP853P40A CMOS 8-bit Single-chip Microcomputer 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. Also, this IC provides power-on reset and sleep functions. The designers have ensured low power consumption for these powerful microcomputers. The CXP853P40A is the one-chip PROM version of the CXP85340A with on-chip mask ROM, providing the function of being able to write directly into the program. Furthermore, because of the OSD character ROM can also be written directly into, it is suitable for evaluation use during system development and for small quantity production. 64 pin SDIP (PIastic) 64 pin QFP (PIastic) in an I2C system, provided that the system conforms to the I2C Standard Specifications as defined by Philips. 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...
