CXP84120/84124
CMOS 8-bit Single Chip Microcomputer
Description
The CXP84120/84124 is a CMOS 8-bit single chip
80 pin QFP (Plastic)
micro-computer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, remote control reception
circuit and other servo systems besides the basic
configurations of 8-bit CPU, ROM, RAM, and I/O
port.
The CXP84120/84124 also provides a power-on
reset function and a sleep/stop function that enables lower power consumption.

Description
(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 ports. I/O can be set in a unit of single
bit. Incorporation of pull-up resistor can be set
through the software in a unit of 4 bits.
(8 pins)
External interruption
request inputs.
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 generation circuit.
Connect a 32kHz crystal oscillator between TEX and TX.
For usage as event input, connect clock oscillation source 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.
