GENERAL DESCRIPTION
programmers may be used. The MX27L512 supports
intelligent fast programming algorithm which can result
in programming time of less than fifteen seconds.
The MX27L512 is a 3V only, 512K-bit, One-Time
Programmable Read Only Memory. It is organized as
64K words by 8 bits per word, operates from a single
+3volt supply, has a static standby mode, and features
fast single address location programming. All program-
