MR27V6452D

4,194,304-Word x 16-Bit or 8,388,608-Word x 8-Bit
8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM

DESCRIPTION

The MR27V6452D is a 64Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 4,194,304 word x 16bit and 8,388,608 word x 8
bit. The MR27V6452D operates on a single +3.3V power supply and is TTL compatible. The MR27
V6452D provides Page mode which can greatly reduce the read access time. Since the MR27V6452
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V6452D 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 package.

FEATURES

• 4,194,304 word x 16bit / 8,388,608 word x 8bit electrically switchable configuration

• Single +3.3V power supply

• Access time 120ns
Page mode access time 30ns

• Input / Output TTL compatible

• Three-state output

• Package
44-pin plastic SOP (SOP44-P-600-1.27-K)
