Pro t(s) Programming
te c When delivered, all bits of the M27V320 are in the
le u '1' state. Data is introduced by selectively pro-
d gramming '0's into the desired bit locations. Al-
so ro though only '0's will be programmed, both '1's and
OObbsolete P '0's can be present in the data word. The M27V320
is in the programming mode when VPP input is at
12.5V, GVPP is at VIH and E is pulsed to VIL. The
data to be programmed is applied to 16 bits in par-
allel to the data output pins. The levels required for
the address and data inputs are TTL. VCC is spec-
ified to be 6.25V ± 0.25V.
