Description

The CXP83412 are a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time base timer, 32kHz timer/counter, LCD controller/ driver, remote control receiving circuit and PWM output, as well as basic configurations like 8-bit CPU, ROM, RAM and I/O port. They are integrated into a single chip.
Also CXP83412 sleep/ stop function which enables to lower power consumption.
