Description
The CXP508L4/508L6 is a CMOS 4-bit micro-
computer 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, 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.
