GENERAL DESCRIPTION
The MX27C4000 is a 5V only, 4M-bit, One Time
Programmable Read Only Memory. It is organized as
512K words by 8 bits per word, operates from a single
+5 volt 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
MX27C4000
4M-BIT [512K x8] CMOS EPROM
• Operating current: 40mA
• Standby current: 100uA
• Package type:
- 32 pin plastic DIP
- 32 pin PLCC/SOP

programmers may be used. The MX27C4000 supports
a intelligent fast programming algorithm which can result
in programming time of less than two minutes.
This EPROM is packaged in industry standard 32 pin
dual-in-line packages, 32 lead PLCC, 32 lead SOP, and
32 lead TSOP packages.
