Programming
The M27V160 has been designed to be fully com-
patible with the M27C160. As a result the
M27V160 can be programmed as the M27C160
on the same programming equipments applying
12.75V on V
same PRESTO III algorithm. When delivered (and
after each erasure for UV EPROM), all bits of the
M27V160 are in the ’1’ state. Data is introduced by
selectively programming ’0’s to the desired bit lo-

cations. 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 expo-
sure to ultraviolet light (UV EPROM). The
M27V160 is in the programming mode when V
input is at 12.5V, G is at V
The data to be programmed is applied to 16 bits in
parallel to the data output pins. The levels required
for the address and data inputs are TTL. V
