GENERAL DESCRIPTION
The MX27C4100/4096 is a 5V only, 4M-bit, One Time
Programmable Read Only Memory. It is organized as
256K words by 16 bits per word(MX27C4096), 512K x 8
or 256K x 16(MX27C4100), operates from a single + 5
volt supply,hasastaticstandby mode,andfeaturesfast
single address location programming. All programming
signals are TTL levels, requiring a single pulse. For
programmingoutsidefromthesystem,existingEPROM
programmers may be used. The MX27C4100/4096
supports a intelligent fast programming algorithm which

This EPROM is packaged in industry standard 40 pin
dual-in-line packages, 40 lead SOP, and 44 lead PLCC
packages.
