CMOS 8-bit Single Chip Microcomputer
For the availability of this product, please contact the sales office.
Description
The CXP856P40 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.
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 small-
quantity production.
