MR27V1652D
1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit
8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM
DESCRIPTION
1A
The MR27V1652D is a 16Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 1,048,576 word x 16bit and 2,097,152 word x 8
bit. The MR27V1652D operates on a single +3.3V power supply and is TTL compatible. The MR27
V1652D provides Page mode which can greatly reduce the read access time. Since the MR27V1652
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V1652D 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 , 44-pin TSOP or 48-pin TSOP packages.
FEATURES
• 1,048,576 word x 16bit / 2,097,152 word x 8bit electrically switchable configuration
• Single +3.3V power supply
• Access time 80ns
Page mode access time 30ns
• Input / Output TTL compatible
• Three-state output
