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:
- 28 pin plastic DIP
- 32 pin PLCC
- 28 pin 8 x 13.4 mm TSOP(I)
programmers may be used. The MX27L512 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.
