MSM27C852CZ
524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit
8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM
DESCRIPTION
The MSM27C852CZ is a 8Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 524,288 word x 16bit and 1,048,576 word x 8bit.
The MSM27C852CZ operates on a single +5V power supply and is TTL compatible. The MSM27C8
52CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C852
CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The
MSM27C852CZ 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 44-pin TSOP packages.
FEATURES
• 524,288 word x 16bit / 1,048,576 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)
44-pin plastic TSOP (TSOP II 44-P-400-0.80-K)
