Data Sheet

Product Identification

The Product Identification mode identifies the devices as

SST29SF020, SST29SF040 and SST29VF020,

SST29VF040 and manufacturer as SST. This mode may

be accessed by software operations. Users may use the

Software Product Identification operation to identify the part

(i.e., using the device ID) when using multiple manufactur-

ers in the same socket. For details, see Table 4 for software

operation, Figure 11 for the Software ID Entry and Read

timing diagram, and Figure 18 for the Software ID Entry

command sequence flowchart.

Product Identification Mode Exit/Reset

In order to return to the standard Read mode, the Software

Product Identification mode must be exited. Exit is accom-

plished by issuing the Software ID Exit command

sequence, which returns the device to the Read operation.

Please note that the Software ID Exit command is ignored

during an internal Program or Erase operation. See Table 4

for software command codes, Figure 12 for timing wave-

form, and Figure 18 for a flowchart.
