MR27V852D
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 MR27V852D 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 MR27V852D operates on a single +3.3V power supply and is TTL compatible. The MR27V852D
provides Page mode which can greatly reduce the read access time. Since the MR27V852D
operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V852D 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.
