CXP858P56A

CXP858P56A CMOS 8-bit Single Chip Microcomputer Description The CXP858P56A is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time-base timer, closed caption decoder, data slicer, on-screen display function, I2C bus interface, PWM output, remote control reception circuit, HSYNC counter and watchdog timer as well as basic configuration like 8-bit CPU, PROM, RAM and I/O port. Also this IC provides a power-on reset function and sleep function that enables to lower power consumption. The CXP858P56A is the PROM-incorporated version of the CXP85856A with built-in mask ROM. This provides the additional feature of being able to write directly into the program (also into the OSD character ROM or caption character ROM possible). Thus, it is most suitable for evaluation use during system development and for small-quantity production. 64 pin SDIP (PIastic) 64 pin QFP (PIastic) Structure Silicon gate CMOS IC Features A wide instruction set (213 instructions) which covers various types of data – 16-bit operation/multiplication and division/Boolean bit operation instructions Minimum instruction cycle 333ns at 12MHz operation Incorporated PROM 56K bytes (Programming) 4.5K bytes (OSD) 3K bytes (Caption) Incorporated RAM 2176 bytes (Excludes the closed caption decoder and on-screen display VRAM) Peripheral functions – A/D converter 8-bit 6-channel successive approximation method (Conversion time of 26.7µs at 12MHz) – Serial interface 8-b...
