Programming
Whendelivered, all bits of theM27C516are in the
’1’state.Data isintroducedbyselectivelyprogram-
ming ’0’s into the desired bit locations. Although
only’0’swillbe programmed,both ’1’s and’0’scan
bepresentinthedata word.TheM27C516isin the
programmingmode whenV
PP
inputis at 12.75V,E
is at V
IL
and P is pulsed to V
IL
. The data to be
programmed is appliedto 16 bits in parallel to the
data output pins. The evels required for the ad-
dressand data inputs are TTL. V
CC
is specifiedto
be 6.25V
±
0.25V.
