CXP822P24
CMOS 8-bit Single Chip Microcomputer
Description
The CXP822P24 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 tube
controller/driver, remote control reception circuit, CTL
duty detection circuit, 14-bit PWM output and high-
speed output circuit besides the basic configurations
of 8-bit CPU, PROM, RAM, and I/O port.
The CXP822P24 also provides sleep/stop function
that enables lower power consumption.
CXP822P24 is the PROM-incorporated version of
the CXP82224 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 producton.

∗1 VIN and VOUT must not exceed VDD + 0.3V.
∗2 Specifies output current of general-purpose l/O ports.
∗3 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 LSl.
