Preliminary Specifications

Product Identification

The Product Identification mode identifies the device as the

SST39VF088 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 10 for the Software ID Entry and Read

timing diagram and Figure 15 for the Software 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. Exit is accom-

plished by issuing the Software ID Exit command

sequence, which returns the device to the Read operation.

This command may also be used to reset the device to the

Read mode after any inadvertent transient condition that

apparently causes the device to behave abnormally, e.g.,

not read correctly. Please note that the Software ID Exit

command is ignored during an internal Program or Erase

operation. See Table 4 for software command codes and

Figure 15 for a flowchart.
