Description

CXP5076/5078 is a CMOS 4-bit microcomputer which consists of 4-bit CPU, ROM, RAM, I/O port, 8-bit timer, 8-bit timer/counter, 18-bit time base timer, 8-bit serial I/O, vector interruption, power on reset function, liquid crystal displayer (LCD) controller/driver, D/A conversion 14-bit PWM output port, a remote control reception circuit with noise eliminating circuit, 3-bit A/D converters, a 32kHz timer/event counter and a power supply voltage detection reset function. They are integrated into a single chip with the standby function, etc. which are to be operated at a low power consumption.
