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.

MR27V3202D
2,097,152-Word x 16-Bit or 4,194,304-Word x 8-Bit
Production Programmed Read Only Memory (P2ROM)
DESCRIPTION
1A
The MR27V3202D is a 32Mbit Production Programmed Read-Only Memory (P2ROM) whose
configuration can be electrically switched between 2,097,152 word x 16bit and 4,194,304 word x 8
bit. The MR27V3202D operates on a single +3V-3.3V power supply and is TTL compatible. Since
the MR27V3202D operates asynchronously , external clocks are not required , making this device
easy-to-use. The MR27V3202D is suitable as large-capacity fixed memory for microcomputers and
data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 44-
pin SOP or 48-pin TSOP packages.
FEATURES
• 2,097,152 word x 16bit / 4,194,304 word x 8bit electrically switchable configuration
