MSM27C1602CZ
1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit One Time PROM
DESCRIPTION
1A
The MSM27C1602CZ 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 8 bit. The MSM27C1602CZ operates on a single +5V power supply and is TTL compatible. Since the MSM27C1602CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C1602CZ 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 48-pin TSOP packages.
