GENERAL DESCRIPTION
The MX27C512 is a 5V only, 512K-bit, One-Time
Programmable Read Only Memory. It is organized as
64K words by 8 bits per word, operates from a single
+5volt 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 MX27C512 supports
intelligent fast programming algorithm which can result
in programming time of less than fifteen seconds.
This EPROM is packaged in industry standard 28 pin
dual-in-line packages 32 lead PLCC, and 28 lead
TSOP(I) packages.
