MX27C8000A
GENERAL DESCRIPTION
The MX27C8000A is a 5V only, 8M-bit, ultraviolet Eras-
able Programmable Read Only Memory. It is organized
as 1M words by 8 bits per word, 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
programming outside from the system, existing EPROM
programmers may be used. The MX27C8000A supports
a intelligent fast programming algorithm which can result
in programming time of less than two minutes.
This EPROM is packaged in industry standard 32 pin
dual-in-line packages, 32 lead PLCC, 32 lead SOP and 32
lead TSOP packages.
