SST29EE010-120-4C-EH SST [Silicon Storage Technology, Inc], SST29EE010-120-4C-EH Datasheet - Page 4

• Manufacturer Part Number: SST29EE010-120-4C-EH
• Description: 1 Megabit (128K x8) Page-Mode EEPROM
• Manufacturer: SST [Silicon Storage Technology, Inc]

Single power supply reprogrammable nonvolatile memo-
ries may be unintentionally altered. SST strongly recom-
mends that Software Data Protection (SDP) always be
enabled. The SST29EE010/29LE010/29VE010 should
be programmed using the SDP command sequence. 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
The product identification mode identifies the device as
the SST29EE010/29LE010/29VE010 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 SST29EE010/29LE010/29VE010. Users may
wish to use the software product identification operation
to identify the part (i.e. using the device code) when using

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 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)
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.
