¡ Semiconductor 1A MSM27C3202CZ 2,097,152-Word x 16-Bit or 4,194,304-Word x 8-Bit One Time PROM DESCRIPTION The MSM27C3202CZ is a 32Mbit electrically Programmable Read-Only Memory whose configuration can be electrically switched between 2,097,152 word x 16bit and 4,194,304 word x 8 bit. The MSM27C3202CZ operates on a single +5V power supply and is TTL compatible. Since the MSM27C3202CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C3202CZ 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 44-pin SOP or 44-pin TSOP packages.
