Data Sheet
Product Identification
The product identification mode identifies the device as the
SST29EE/LE/VE512 and manufacturer as SST. This mode
is accessed via software. For details, see Table 4, Figure
11 for the software ID entry, and read timing diagram and
Figure 18 for the ID entry command sequence flowchart.

Product Identification Mode Exit
In order to return to the standard read mode, the Software
Product Identification mode must be exited. Exiting is
accomplished by issuing the Software ID Exit (reset) opera-
tion, which returns the device to the Read operation. The
Reset operation may also be used to reset the device to the
Read mode after an inadvertent transient condition that
apparently causes the device to behave abnormally, e.g.,
not read correctly. See Table 4 for software command
codes, Figure 12 for timing waveform, and Figure 18 for a
flowchart.
