1 Megabit Page Mode EEPROM
SST29EE010, SST29LE010, SST29VE010
Single power supply reprogrammable nonvolatile
memories may be unintentionally altered. SST strongly
recommends that Software Data Protection (SDP) al-
ways be enabled. The 29EE010/29LE010/29VE010
should be programmed using the SDP command se-
quence. SST recommends the SDP Disable Command
Sequence not be issued to the device prior to writing.
Please refer to the following Application Notes located at
the back of this databook for more information on using
SDP:

Product Identification Mode Exit
In order to return to the standard read mode, the Soft-
ware Product Identification mode must be exited. Exiting
is accomplished by issuing the Software ID Exit (reset)
operation, 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 11 for timing wave-
form and Figure 17 for a flowchart.
multiple manufacturers in the same socket. For details,
see Table 3 for hardware operation or Table 4 for
software operation, Figure 10 for the software ID entry
and read timing diagram and Figure 17 for the ID entry
command sequence flowchart. The manufacturer and
device codes are the same for both operations.

Product Identification
The product identification mode identifies the device as
the 29EE010/29LE010/29VE010 and manufacturer as
SST. This mode may be accessed by hardware or
software operations. The hardware operation is typically
used by a programmer to identify the correct algorithm
for the 29EE010/29LE010/29VE010. Users may wish to
use the software product identification operation to iden-
tify the part (i.e. using the device code) when using
