Description

The CXP84716/84720/84724 is a CMOS 8-bit micro-

computer integrating on a single chip an A/D converter,

serial interface, timer/counter, time base timer, capture

timer/counter, FRC capture unit, high-precision timing

pattern generation circuit, PWM output, and the like

besides the basic configurations of 8-bit CPU, ROM,

RAM, and I/O port.

The CXP84716/84720/84724 also provides the

sleep/stop functions that enable to execute the power-

on reset function and lower the power consumption.
