internal Program or Erase operation. See Table 4 for soft-
ware command codes, Figure 12 for timing waveform and
Figure 18 for a flowchart.
Design Considerations
SST recommends a high frequency 0.1 μF ceramic capac-
itor to be placed as close as possible between V
DD
and
V
SS
, e.g., less than 1 cm away from the V
DD
pin of the
device. Additionally, a low frequency 4.7 μF electrolytic
capacitor from V
DD
to V
SS
should be placed within 1 cm of
the V
DD
pin.
