MR27V802D

524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit One Time PROM

DESCRIPTION

The MR27V802D is a 8Mbit electrically Programmable Read-Only Memory whose configuration can

be electrically switched between 524,288 word x 16bit and 1,048,576 word x 8bit. The MR27V802D
operates on a single +3V-3.3V power supply and is TTL compatible. Since the MR27V802D
operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V802D 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.

FEATURES

• 524,288 word x 16bit / 1,048,576 word x 8bit electrically switchable configuration

• Single +3V-3.3V power supply

• Access time 100ns access time (Vcc=+3V)
80ns access time (Vcc=+3.3V)

• Input / Output TTL compatible

• Three-state output

• Packages
42-pin plastic DIP (DIP42-P-600-2.54) (Product name : MR27V802DRA)
44-pin plastic SOP (SOP44-P-600-1.27-K) (Product name : MR27V802DMA)
44-pin plastic TSOP (TSOP II 44-P-400-0.80-K) (Product name : MR27V802DTP)
