1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit
8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM
DESCRIPTION
1A
The MSM27C1652CZ is a 16Mbit electrically Programmable Read-Only Memory with page mode.
Its configuration can be electrically switched between 1,048,576 word x 16bit and 2,097,152 word x
8bit. The MSM27C1652CZ operates on a single +5V power supply and is TTL compatible. The
MSM27C1652CZ provides Page mode which can greatly reduce the read access time. Since the
MSM27C1652CZ operates asynchronously , external clocks are not required , making this device
easy-to-use. The MSM27C1652CZ 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.
FEATURES
• 1,048,576 word x 16bit / 2,097,152 word x 8bit electrically switchable configuration
• Single +5V power supply
• Access time 100ns
Page mode access time 50ns
• Input / Output TTL compatible
• Three-state output
• Packages
42-pin plastic DIP (DIP42-P-600-2.54)
44-pin plastic SOP (SOP44-P-600-1.27-K)
48-pin plastic TSOP (TSOP II 48-P-550-0.80-K)
