Data Sheet
Single power supply reprogrammable nonvolatile memo-
ries may be unintentionally altered. Greenliant strongly rec-
ommends that Software Data Protection (SDP) always be
enabled. The GLS29EE512 should be programmed using
the SDP command sequence. Greenliant recommends the
SDP Disable Command Sequence not be issued to the
device prior to writing.
Please refer to the following Application Notes for more
information on using SDP:

Product Identification
The Product Identification mode identifies the device as the
GLS29EE512 and manufacturer as Greenliant. 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.
