Description
The CXP85632/85640 is a CMOS 8-bit micro-
64 pin SDIP (PIastic)
64 pin QFP (PIastic)
computer 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 receiver, HSYNC counter and watchdog
timer as well as basic configuration like 8-bit CPU,
ROM, RAM and I/O port.
Also this IC provides power-on reset function and
sleep function which enables to lower power
consumption.
