Programming
The M27V201 has been designed to be fully com-
patible withthe M27C2001 and hasthe same elec-
tronic signature. As a result the M27V201 can be
programmed as the M27C2001 on the same pro-
gramming equipments by applying 12.75V on V
PP
and 6.25V on V
CC
by the use of the same PRES-
TO II algorithm. When delivered (and after each
erasure for UV EPROM), all bits of the M27V201
are inthe ’1’state.Data is introduced by selectively
programming ’0’s into the desired bit locations. Al-
though only ’0’s will be programmed, both ’1’s and
’0’s can be presentin the data word. The only way
to change a ’0’to a ’1’is by die exposition to ultra-
violet light (UV EPROM). The M27V201 is in the
programming mode when V
PP
input is at 12.75V,
E is at V
IL
and P 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 data inputs are TTL. V
CC
is specified to
be 6.25V
±
0.25V.
