GENERAL DESCRIPTION
programmersmaybeused. TheMX27C8000supports
aintelligentfastprogrammingalgorithmwhichcanresult
in programming time of less than two minutes.
The MX27C8000 is a 5V only, 8M-bit, One Time
ProgrammableReadOnlyMemory.Itisorganizedas1M
words by 8 bits per word, operates from a single +5 volt
supply, has a static standby mode, and features fast
singleaddresslocationprogramming. Allprogramming
signals are TTL levels, requiring a single pulse. For
