GENERAL DESCRIPTION
The MX27C8111 is a 8M-bit, One Time Programmable
Read Only Memory with page mode. It is organized as
1M x 8 or 512K x 16, operates from a single + 5 volt
supply, has a static standby mode, and features fast
singleaddresslocationprogramming. Allprogramming
signals are TTL levels, requiring a single pulse. For
programming outside from the system, existing
EPROM programmers may be used. The MX27C8111
supportsaintelligentfastprogrammingalgorithmwhich
canresultinprogrammingtimeoflessthantwominutes.
MX27C8111 provides Page Read Access Mode which
can greatly reduce the read access time. Normal read
accesstimeandPageModereadaccesstime isasfast
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 One Time Programmable Read Only Memory is
packagedinindustrystandard42pindual-in-lineplastic
package and 44 pin SOP packages.
