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.

FEATURES

• 2,097,152 word x 16bit / 4,194,304 word x 8bit electrically switchable configuration

• Single +5V power supply

• Access time 100ns

• Input / Output TTL compatible

• Three-state output

• Packages
44-pin plastic SOP (SOP44-P-600-1.27-K)
48-pin plastic TSOP (TSOP II 48-P-550-0.80-K)
