GENERAL DESCRIPTION

may be used. The MX27C256 supports intelligent fast

programming algorithm which can result in program-

ming time of less than ten seconds.

The MX27C256 is a 5V only, 256K-bit, One-Time

Programmable Read Only Memory. It is organized as

32Kby8bits, operatesfromasingle+5volt supply, has

astaticstandby mode, andfeaturesfastsingleaddress

locationprogramming. AllprogrammingsignalsareTTL

levels, requiring a single pulse. For programming from

outside the system, existing EPROM programmers

This EPROM is packaged in industry standard 28 pin

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

TSOP(I) packages.
