MR27V401D

524,288-Word x 8-Bit One Time PROM

DESCRIPTION

The MR27V401D is a 4Mbit electrically Programmable Read-Only Memory organized as 524,288

word x 8bit. The MR27V401D operates on a single +3V-3.3V power supply and is TTL compatible.
Since the MR27V401D operates asynchronously , external clocks are not required , making this
device easy-to-use. The MR27V401D 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 32-pin DIP, 32-pin SOP or 32-pin TSOP packages.

FEATURES

• 524,288 word x 8bit

• Single +3V-3.3V power supply

• Access time 80ns access time (Vcc=+3V)
70ns access time (Vcc=+3.3V)

• Input / Output TTL compatible

• Three-state output

• Packages
32-pin plastic DIP (DIP32-P-600-2.54) (Product name : MR27V401DRA)
32-pin plastic SOP (SOP32-P-525-1.27-K) (Product name : MR27V401DMA)
32-pin plastic TSOP (TSOP I 32-P-814-0.50-K) (Product name : MR27V401DTA)
