Programming
The M27V102has been designed to be fullycom-
patible with the M27C1024 and has the same
elecronic signature.As a result the M27V102 can
be programmed as the M27C1024 on the same
programming equipmentsapplying12.75V on V
PP
and6.25Von V
CC
bythe useof thesamePRESTO
II algorithm. When delivered (and after each ’1’s
erasure for UV EPROM), all bits of the M27V102
arein the’1’state.Dataisintroducedbyselectively
programming ’0’s into the desired bit locations.
Although only ’0’s will be programmed, both ’1’s
and’0’scan bepresentin thedata word. Theonly
way to change a ’0’ to a ’1’ is by die exposure to
ultraviolet light (UV EPROM). The M27V102 is in
the programming mode when V
PP
input is at
12.75V,E is atV
IL
and P is pulsedto V
IL
. The data
to be programmed is applied to 16 bits in parallel
to the data outputpins. Thelevelsrequired for the
addressand data inputs are TTL.V
CC
is specified
to be 6.25V
±
0.25V.
