GENERAL DESCRIPTION
The MX27C256 is a 5V only, 256K-bit, ultraviolet Eras-
able Programmable Read Only Memory. It is organized
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

EPROM programmers may be used. The MX27C256
supports intelligent fast programming algorithm which
can result in programming time of less than ten seconds.
This EPROM is packaged in industry standard 28 pin
dual-in-line packages, 32 lead PLCC, and 28 lead
TSOP
(I
) packages.
