CXP811P24
CMOS 8-bit Single Chip Microcomputer
Description
The CXP811P24 is a CMOS 8-bit microcomputer
which consists of A/D converter, serial interface,
timer/counter, time base timer, PWM output, as well
as basic configurations like 8-bit CPU, PROM, RAM
and I/O port. They are integrated into a single chip.
Also the CXP811P24 provides power-on reset
function, sleep/stop function which enables to lower
power consumption .
The CXP811P24 is the PROM-incorporated version
of the CXP81120/81124 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.

∗1 VIN and VOUT should not exceed VDD + 0.3V. (CS0 and SI0 excluded.)
Note) Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should
be conducted under the recommended operating conditions. Exceeding those conditions may adversely
affect the reliability of the LSI.
