Programming
The M27V512 has been designed to be fully com-
patible with the M27C512 and has the same elec-
tronic signature. As a result the M27V512 can be
programmed as the M27C512 on the same pro-
gramming equipments applying 12.75V on V
PP
and 6.25V on V
CC
by the use of the same PRES-
TO IIB algorithm. When delivered (and after each
erasure for UV EPROM), all bits of the M27V512
are in the ’1’ state. Data is introduced by selective-
ly programming ’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 tochange a ’0’ to a ’1’is by die exposure to ul-
traviolet light (UV EPROM).TheM27V512 is in the
programming mode when V
PP
input is at 12.75V
and E is pulsed toV
IL
. The data to be programmed
is applied to 8 bits in parallel to the data output
pins.The levels required for the address and data
inputs are TTL. V
CC
is specified to be 6.25V
±
0.25V.
The M27V512 can use PRESTO IIBProgramming
Algorithm that drastically reduces the program-
ming time (typically less than 6 seconds). Never-
theless
to
achieve
programming equipments, PRESTO Program-
ming Algorithm can be used as well.
