GENERAL DESCRIPTION
The MX27L4000 is a 4M-bit, One Time Programmable
Read Only Memory. It is organized as 512K words by 8
bits per word, operates from a single +3 volt supply, has
a static standby mode, and features fast single address
location programming. All programming signals are TTL
levels, requiring a single pulse. For programming out-
side from the system, existing EPROM programmers
Operating current: 20mA @ 3.6V, 5MHz
Standby current: 50uA
Package type:
- 32 pin plastic DIP
- 32 pin PLCC/SOP
- 32pin TSOP
REV. 2.7, AUG. 26, 2003
P/N: PM00255
may be used. The MX27L4000 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
(I
) packages.
