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 MR53V1652J is a 16Mbit Read-Only Memory whose configuration can be electrically switched
between 1,048,576 word x 16bit and 2,097,152 word x 8bit. The MR53V1652J operates
asynchronously, external clocks are not required, making this device easy-to-use. The MR53V1652J 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 42-pin DIP, 44-pin SOP or 44-pin TSOP
packages.
