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  
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  
• Packages
