CXP826P16
CMOS 8-bit Single Chip Microcomputer
Description
The CXP826P16 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, fluorescent
display controller/driver, remote control receiver and
32kHz timer/counter.
This device also includes a power-on reset function
and sleep/stop functions which can be used to
achieve low power consumption.
The CXP826P16 is the PROM-incorporated version of
the CXP82616 with built-in mask ROM, and it is able to
write directly into the program. Thus, it is most suitable
for evaluation use during system development and for
small-quantity production.

Functions
(Port H)
2-bit I/O port. I/O can be set in a bit unit. Incorporation of pull-up resistor
can be set through the software in a unit of 2 bits.
(2 pins)
(Port F)
8-bit output port.
(8 pins)
Segment signal output for FDP.
Segment signal output for FDP.
Output for FDP timing and segment signals.
Timing signal output for FDP.
(Port D)
8-bit output port.
(8 pins)
Segment signal output for FDP.
Provides voltage for FDP when on-chip resistor is selected under mask option.
Crystal connectors for system clock oscillation. When the clock is
supplied externally, input to EXTAL; opposite phase clock should be
input to XTAL.
(Port H)
2-bit input
port.
(2 pins)
Crystal connectors for 32kHz timer/counter clock
oscillation circuit. Connect a 32kHz crystal oscillator
between TEX and TX. For usage as event input, connect
clock oscillation source to TEX, and leave TX open.
Low-level active. System reset. RST is input pin.
Positive power supply pin for writing of built-in PROM.
Under normal operating conditions, connect to VDD.
Vcc supply.
