CXP841P24
CMOS 8-bit Single Chip Microcomputer
Description
80 pin QFP (Plastic)
The CXP841P24 is a CMOS 8-bit 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 CXP841P24 also provides a sleep/stop function
that enables lower power consumption.
This IC is the PROM-incorporated version of the
CXP84124 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.

The high current drive transistor is the N-ch transistor of Port C (PC).
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.
