GENERAL DESCRIPTION
The MX27C4000A is a 5V only, 4M-bit, One Time
Programmable Read Only Memory. It is organized as
512K 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-
ming signals are TTL levels, requiring a single pulse. For
programming outside from the system, existing EPROM
programmers may be used. The MX27C4000A
supports a intelligent fast programming algorithm which
can result in programming time of less than two minutes.
This One Time Programmable Read Only Memory is
packaged in industry standard 32 pin dual-in-line plastic,
32 lead PLCC, 32 lead SOP, 32 lead TSOP packages.
