Oki Electric Industry MSM64164C
The MSM64164C is a low power 4-bit microcontroller that employs Oki's original CPU core nX4/20. The MSM64164C is best suitable for applications such as low power, high precision thermometers and hygrometers. The MSM64P164 is a one-time-programmable ROM-version product having one-time PROM (OTP) as internal program memory.GENERAL DESCRIPTION
The MSM64P164 is used to evaluate the software development. The MSM64P164 differs from the MSM64164C in the polarity of the power supply.FEATURES
