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
