GENERAL DESCRIPTION
EPROMprogrammersmaybeused. TheMX27C1100/
1024 supports a intelligent fast programming algorithm
which can result in programming time of less than thirty
seconds.
The MX27C1024 is a 5V only, 1M-bit, One Time
Programmable Read Only Memory. It is organized as
64K words by 16 bits per word(MX27C1024), 128K x 8
or 64K x 16(MX27C1100), operates from a single + 5
volt supply, has a static standby mode, and features
fastsingleaddresslocationprogramming. Allprogram-

programming outside from the system, existing
This EPROM is packaged in industry standard 40 pin
dual-in-line packages, 40 lead SOP and 44 lead PLCC
packages.
