CXP820P60
CMOS 8-bit Single Chip Microcomputer
Description
The CXP820P60 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time-base
timer, capture timer/counter, fluorescent display panel
controller/driver, remote control reception circuit, and
PWM output circuit besides the basic configurations
of 8-bit CPU, ROM, RAM, and I/O port.
The CXP820P60 also provides sleep/stop function
that enables lower power consumption.
CXP820P60 is the PROM-incorporated version of the
CXP82052/82060 with bult-in mask ROM. This provides
the additional feature of being able to write directly into
the program. Thus, it is most suitable for evaluation
use during system development and for small-quantity
production.
