DESCRIPTION
FEATURES
524,288 word x 16bit / 1,048,576 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
42-pin plastic DIP (DIP42-P-600-2.54) (Product name : MR27V852DRA)
44-pin plastic SOP (SOP44-P-600-1.27-K) (Product name : MR27V852DMA)
44-pin plastic TSOP (TSOP II 44-P-400-0.80-K) (Product name : MR27V852DTP)
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.
