M27C452CZ Datasheet | OKI Electric

DESCRIPTION 1A The MSM27C452CZ is a 4Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 262,144 word x 16bit and 524,288 word x 8bit. The MSM27C452CZ operates on a single +5V power supply and is TTL patible. The MSM27C4 52CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C452 CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C452CZ is suitable as large-capacity fixed memory for microputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 40-pin DIP , 40-pin SOP or 44-pin TSOP packages.
