Programming
When delivered (and after each erasure for UV
EPROM), all bits of the M27C4001 are in the ”1”
state. Data is introduced by selectively program-
ming ”0”s into the desired bit locations. Although
only ”0”s will be programmed, both ”1”s and ”0”s
can be present in the data word. The only way to
change a ”0” to a ”1” is by die expositionto ultra-
violet light (UV EPROM). The M27C4001 is in the
programmingmode whenV
PP
inputisat 12.75V,G
is at V
IH
and E is pulsed to V
IL
. The data to be
programmed is applied to 8 bits in parallel to the
data output pins. The levels required for the ad-
dress and datainputs are TTL. V
CC
is specified to
be 6.25V
±
0.25V.
