POWER SUPPLY
Power Up
The memory Command Interface is reset on pow-
er up to Read Array. The device does not accept
commands on the first rising edge of W, if both W
and E are at V
IL
with G at V
IH
during power-up.
Any write cycle initiation is blocked when V
CC
is
below V
LKO
.
Supply Rails
Normal precautions must be taken for supply volt-
age decoupling; each device in a system should
have the V
CC
rail decoupled with a 0.1
μ
F capacitor
close to the V
CC
and V
SS
pins. The PCB trace
widths should be sufficient to carry the V
CC
pro-
gram and erase currents required.
