GENERAL DESCRIPTION
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-
ming signals are TTL levels, requiring a single pulse. For
programming outside from the system, existing EPROM
MX27L512
512K-BIT [64K x 8] CMOS EPROM
• Operating current: 10mA@ 3.6V, 5MHz
• Standby current: 10uA
• Package type:
