Description
The CXP854P60 are a highly integrated micro-
computers composed of a 8-bit CPU, PROM, RAM,
and I/O ports. These chips feature many other high-
performance circuits in a single-chip CMOS design,
including an A/D converter, serial interface,
timer/counter, time-base timer, vector interrupt, on-
screen display function, I
2
C bus interface, PWM
generator, remote control receiver, HSYNC counter,
and watchdog timer.
Also, the CXP854P60 provides power-on reset
and sleep functions. The designers have ensured
low power consumption for these powerful micro-
computers.
Incorporating a one-time PROM, the CXP854P60
has an equivalent function to the CXP85460 and
character ROM for OSD can be written. Therefore, it
is suitable for evaluation in system development
and for the production of small amounts.
