CXP5084/5086

CMOS 4-bit Single Chip Microcomputer

Description

64 pin SDIP (Plastic)

64 pin QFP (Plastic)

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.
