GENERAL DESCRIPTION
The MX27C2000 is a 5V only, 2M-bit, One Time
Programmable Read Only Memory. It is organized as
256K words by 8 bits per word, operates from a single +
5 volt supply, has a static standby mode, and features
fast single address location programming. All program-
mingsignalsareTTLlevels,requiringasinglepulse.For
programmingoutsidefromthesystem,existingEPROM
programmers may be used. The MX27C2000 supports
aintelligentfastprogrammingalgorithmwhichcanresult
in programming time of less than one minute.
This EPROM is packaged in industry standard 32 pin
dual-in-line packages, 32 lead SOP, 32 lead PLCC and
32 lead TSOP (I) packages.
