CXP5084/5086
CMOS 4-bit Single Chip Microcomputer
For the availability of this product, please contact the sales office.
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.
64 pin SDIP (Plastic)
64 pin QFP (Plastic)
