CXP842P24
CMOS 8-bit Single Chip Microcomputer
Description
The CXP842P24 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, and remote control
reception circuit besides the basic configurations of
8-bit CPU, ROM, RAM, and I/O port.
The CXP842P24 also provides a power-on reset
function and a sleep/stop function that enables lower
power consumption.
This IC is the PROM-incorporated version of the
CXP84224 with built-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.
