MR27V1602D

1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit One Time PROM

DESCRIPTION

The MR27V1602D is a 16Mbit electrically Programmable Read-Only Memory whose configuration

can be electrically switched between 1,048,576 word x 16bit and 2,097,152 word x 8bit. The MR27
V1602D operates on a single +3V-3.3V power supply and is TTL compatible. Since the MR27V1602
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V1602D 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 +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 : MR27V1602DRA)
