CXP854P60
CMOS 8-bit Single-chip Microcomputer
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, I2C 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.

Function
CRT display clock oscillator I/O pin.
Oscillator frequency is determined external L, C circuit.
System clock oscillator crystal connection pin. When using an external
clock, input to EXTAL pin and leave XTAL pin open.
"L" level active system reset. This pin also acts as an I/O pin during
power up. While internal power-on reset function is talking place a
"L" level is output.
Test mode input pin. Must be connected to GND.
Positive power supply pin for incorporated PROM writing.
Under normal operating conditions, connect to VDD.
Positive supply voltage pin.
GND. Both Vss pins should be connected to common GND.
