can be tied to V
CC
or can use a separate
supply.
V
SS
Ground.
V
SS
is the reference for all voltage
measurements. The device features two V
SS
pins
which must be both connected to the system
ground.
Note: Each device in a system should have
V
CC
,
V
CCQ
and V
PP
decoupled from V
SS
with a
0.1μF ceramic capacitor close to the pin for
current surge protection (high frequency, in-
herently low inductance capacitors should be
as close as possible to the device). See Figure
8, AC Measurement Load Circuit. The PCB
trace widths should be sufficient to carry the
required V
PP
program and erase currents. See
Table 9, DC Characteristics.
