GENERAL DESCRIPTION
The MX27C1000A is a 5V only, 1M-bit, One Time
Programmable Read Only Memory. It is organized as
128K 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

programmersmaybeused. The MX27C1000Asupports
an intelligent fast programming algorithm which can
result in programming time of less than thirty seconds.
ThisOneTimeProgrammableReadOnly ispackagedin
industry standard 32 pin dual-in-line packages, 32 lead
PLCC, 32 lead SOP and 32 lead TSOP packages.
