Description

The CXP84540/84548 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, PWM output and the like besides the basic configurations of 8-bit CPU, ROM, RAM and I/O port.
The CXP84540/84548 also provide a sleep/stop functions that enable to execute the power-on reset function or lower the power consumption.
