E2E0045-38-96 ¡ Semiconductor MSM64P164 ¡ Semiconductor This version: Sep. 1998 MSM64P164 Previous version: Sep. 1995 4-Bit Microcontroller with Built-in RC Oscillation Type A/D Converter and LCD Driver Pr el im in ar y GENERAL DESCRIPTION The MSM64P164 is a one-time-programmable ROM-version product, which has one-time PROM (OTP) as internal program memory. On the other hand, the MSM64164C is a mask ROMversion product, which has mask ROM as internal program memory. Unlike the mask ROM-version MSM64164C, which has a P-well CMOS structure, the MSM64P164 has been fabricated with the N-well CMOS-structured EEPROM process technology. Therefore, the MSM64P164 differs from the MSM64164C in...
