Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit
The MSM64P155 is a one-time-programmable ROM version product, which has one-time PROM
(OTP) as internal program memory. On the other hand, the MSM64155A is a mask ROM-version
product, which has mask ROM as internal program memory.
Unlike the mask ROM-version MSM64155A which has a P-well CMOS structure, the MSM64P155
has been fabricated with the N-well CMOS-structured EPROM process technology.
Therefore, the MSM64P155 differs from the MSM64155A in the polarity of the power supply for
LCD bias generation and in the external circuit structure.
Unlike the mask ROM-version product, the MSM64P155 cannot be supplied in the form of a chip.
The MSM64P155 is an OTP-version product used to evaluate an application program.
The MSM64P155 has two operation modes, microcontroller operation mode and PROM mode.
The microcontroller operation mode is used to operate the MSM64P155 like a mask ROM-version
product and the PROM mode is used to program or read the PROM.
