Silicon Storage Technology 

Software Data Protection (SDP)

The SST36VF1601/1602 provide the JEDEC standard

Software Data Protection scheme for all data alteration

operations, i.e., Program and Erase. Any Program opera-

tion requires the inclusion of the three-byte sequence.

The three-byte load sequence is used to initiate the

Program operation, providing optimal protection from

inadvertent Write operations, e.g., during the system

power-up or power-down. Any Erase operation requires

the inclusion of six-byte sequence. The SST36VF1601/

1602 are shipped with the Software Data Protection

permanently enabled. See Table 4 for the specific soft-

ware command codes. During SDP command sequence,

invalid commands will abort the device to Read mode

within TRC. The contents of DQ15-DQ8 are “Don’t Care”

during any SDP command sequence.

Common Flash Memory Interface (CFI)

The SST36VF1601/1602 also contain the CFI informa-

tion to describe the characteristics of the device. In order

to enter the CFI Query mode, the system must write

three-byte sequence, same as Software ID Entry com-

mand with 98H (CFI Query command) to address 555H

in the last byte sequence. Once the device enters the CFI

Query mode, the system can read CFI data at the

addresses given in Tables 5 through 7. The system must

write the CFI Exit command to return to Read mode from

the CFI Query mode.

Advance Information

Product Identification

The Product Identification mode identifies the devices

and manufacturer. For details, see Table 4 for software

operation, Figure 13 for the Software ID Entry and Read

timing diagram and Figure 21 for the Software ID Entry

command sequence flowchart.

Product Identification Mode Exit/CFI Mode Exit

In order to return to the standard Read mode, the

Software Product Identification mode must be exited.

Exit is accomplished by issuing the Software ID Exit

command sequence, which returns the device to the

Read mode. 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/CFI Exit command is ignored during an

internal Program or Erase operation. See Table 4 for

software command codes, Figure 15 for timing waveform

and Figure 21 for a flowchart.
