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.
