GENERAL DESCRIPTION
used. The MX27C8100 supports a intelligent fast pro-
gramming algorithm which can result in programming
time of less than two minutes.
TheMX27C8100isa5Vonly,8M-bit,OneTimeProgram-
mable Read Only Memory. It is organized as 1M x 8 or
512K x 16, operates from a single + 5 volt supply, has
a static standby mode, and features fast single address
locationprogramming. AllprogrammingsignalsareTTL
