Description

The CXP5084/5086 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 and a liquid crystal displayer (LCD) controller/ driver. They are integrated into a single clip with the standby function etc. which are to be operated at low power consumption.
