MSM27C401CZ

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

DESCRIPTION

The MSM27C401CZ is a 4Mbit electrically Programmable Read-Only Memory organized as 524,288

word x 8bit. The MSM27C401CZ operates on a single +5V power supply and is TTL compatible.

Since the MSM27C401CZ operates asynchronously , external clocks are not required , making this

device easy-to-use. The MSM27C401CZ 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 +5V power supply

• Access time
