GENERAL DESCRIPTION

EPROM programmers may be used. The MX27C256

supports intelligent fast programming algorithm which

canresultinprogrammingtimeoflessthantenseconds.

The MX27C256 is a 5V only, 256K-bit, ultraviolet Eras-

ableProgrammableReadOnlyMemory. Itisorganized

as 32K by 8 bits, operates from a single + 5volt 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 from outside the system, existing

This EPROM is packaged in industry standard 28 pin

dual-in-line packages, 32 lead PLCC, and 28 lead

TSOP(I) packages.
