MSM27C402CZ
262,144-Word x 16-Bit or 524,288-Word x 8-Bit One Time PROM
DESCRIPTION
1A
The MSM27C402CZ is a 4Mbit electrically Programmable Read-Only Memory whose configuration can be electrically switched between 262,144 word x 16bit and 524,288 word x 8bit. The MSM27C40 2CZ operates on a single +3.3V - 5V power supply and is TTL compatible. Since the MSM27C402 CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C402CZ 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 40-pin DIP , 40-pin SOP or 44-pin TSOP packages.
