CXP508L4/508L6 CMOS 4-bit Single Chip Microputer For the availability of this product, please contact the sales office. Description The CXP508L4/508L6 is a CMOS 4-bit microputer 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.
