Programming
The M27W402 hasbeen designedto be fully com-
patible withthe M27C4002 and hasthe same elec-
tronic signature. As a result the M27W402 can be
programmed as the M27C4002 on the same pro-
gramming equipmentapplying 12.75V on V
PP
and
6.25V on V
CC
by the use of the same PRESTO II
algorithm. Whendelivered (andafter each ‘1’s era-
sure for UV EPROM), all bits of the M27W402 are
in the ’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’ bydie exposureto ultraviolet
light (UV EPROM). The M27W402 is in the pro-
gramming mode when V
PP
input is at 12.75V, G is
at V
IH
and E is pulsed to V
IL
. The data to be pro-
grammed is applied to16 bitsin parallelto thedata
output pins. The levels required for the address
and data inputs are TTL. V
CC
is specified to be
6.25V
±
0.25V.
