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.

Preliminary
DESCRIPTION
The MR533252J is a 32Mbit Read-Only Memory whose configuration can be electrically switched
between 2,097,152 word x 16bit and 4,194,304 word x 8bit. The MR533252J operates asynchronously,
external clocks are not required, making this device easy-to-use. The MR533252J is suitable as large-
capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS
silicon gate technology and is offered in 44-pin SOP or 44-pin TSOP packages.
FEATURES
· 2,097,152word x 16bit / 4,194,304 word x 8bit electrically switchable configuration
· 8word x 16-Bit or 16word x 8-bit / Page read mode
