CXP856P40
CXP856P40 is CMOS 8-bit Single Chip Microcomputer manufactured by Sony Semiconductor Solutions.
Description
The CXP856P40 is a CMOS 8-bit microputer 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. CXP856P40 is the PROM-incorporated version of the CXP85640 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 smallquantity production. 64 pin SDIP (PIastic) 64 pin QFP (PIastic)
