CXP84632/84640/84648
CMOS 8-bit Single Chip Microcomputer
Description
The CXP84632/84640/84648 is a CMOS 8-bit single
80 pin QFP (Plastic)
chip microcomputer integrating on a single chip an
A/D converter, serial interface, timer/counter, time
base timer, capture timer/counter, I2C bus interface,
remote control reception circuit, PWM output, and
32kHz timer/counter besides the basic configurations
of 8-bit CPU, ROM, RAM, and I/O port.
The CXP84632/84640/84648 also provides a sleep/
stop function that enables lower power consumption.

Functions
(Port G)
8-bit I/O port. I/O can be set in a unit of single bits. Incorporation of pull-
up resistor can be set through the software in a unit of 4 bits.
(8 pins)
(Port H)
8-bit I/O port. I/O can be set in a unit of single bits. Incorporation of pull-
up resistor can be set through the software in a unit of 4 bits.
(8 pins)
(Port I)
8-bit I/O port. I/O can be
set in a unit of single
bits. Incorporation of
pull-up resistor can be
set through the software
in a unit of 4 bits.
(8 pins)
External interruption request inputs.
(5 pins)
Serial clock I/O. (CH2)
Serial data input. (CH2)
Serial data output. (CH2)
Crystal connectors for system clock oscillation. When the clock is
supplied externally, input to EXTAL; opposite phase clock should be
input to XTAL.
Crystal connectors for 32kHz timer/counter clock oscillation. For usage
as event counter, input to TEX, and open TX.
Low-level active, system reset.
NC.
Under normal operating conditions, connect to VDD.
Reference voltage input for A/D converter.
A/D converter GND.
Positive power supply.
GND.

∗1 VIN and VOUT must not exceed VDD + 0.3V.
∗2 The large current output is for each pin of Port C (PC), Port F0 (PF0) to Port 3 (PF3).
Note) Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should
be conducted under the recommended operating conditions. Exceeding these conditions may adversely
affect the reliability of the LSI.
