GENERAL DESCRIPTION
The MX27C4111 is a 4M-bit, One Time Programmable
Read Only Memory with page mode. It is organized as
512K x 8 or 256K x 16, operates from a single + 5 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
programmingoutsidefromthesystem,existingEPROM
programmers may be used. The MX27C4111 supports
aintelligentfastprogrammingalgorithmwhichcanresult
in programming time of less than two minutes.
MX27C4111 provides Page Read Access Mode which
can greatly reduce the read access time. Normal read
access time and Page Mode read access time is as fast
as 90/50ns. It is designed to be compatible with all
microprocessors and similar applications in which high
perofmrance, large bit storage and simple interfacing
are important design considerations.
This EPROM is packaged in industry standard 40 pin
dual-in-line packages and 40 pin SOP packages.
