CXP5076/5078

CMOS 4-bit Single Chip Microcomputer

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.

80 pin QFP (Plastic)
