CXP82532/82540
CMOS 8-bit Single Chip Microcomputer
Description
The CXP82532/82540 microcomputer is composed
of a CPU, ROM 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, capture timer/counter, fluorescent display
controller/driver, remote control receiver.
This device also includes a power-on reset function
and sleep/stop functions which can be used to
achieve low power consumption.
80 pin QFP (Plastic)

Description
Provides voltage for FDP when on-chip resistor is selected under mask
option.
Connection for system clock oscillation crystal. When using an external
clock, input normal signal to EXTAL and reverse phase signal to the
XTAL pin.
System reset, active "L". The RST pin is an input/output pin which
outputs a "L" level from the on-chip power-on reset circuit when the
power is turned on. (Mask option)
NC pin is always connected to VDD.
Positive power supply pin.
