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.

MSM27C852CZ
524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit
8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM
DESCRIPTION
1A
The MSM27C852CZ is a 8Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 524,288 word x 16bit and 1,048,576 word x 8bit.
The MSM27C852CZ operates on a single +5V power supply and is TTL compatible. The MSM27C8
52CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C852
CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The
MSM27C852CZ 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 42-pin DIP , 44-pin
SOP or 44-pin TSOP packages.
FEATURES
• 524,288 word x 16bit / 1,048,576 word x 8bit electrically switchable configuration
• Single +5V power supply
• Access time 100ns
Page mode access time 50ns
• Input / Output TTL compatible
• Three-state output
• Packages
42-pin plastic DIP (DIP42-P-600-2.54)
44-pin plastic SOP (SOP44-P-600-1.27-K)
44-pin plastic TSOP (TSOP II 44-P-400-0.80-K)
