Data Sheet
command codes. During SDP command sequence, invalid commands will abort the device to read
mode within TRC. The contents of DQ15-DQ8 can be VIL or VIH, but no other value, during any SDP
command sequence.
Common Flash Memory Interface (CFI)
The SST39VF1601C/1602C also contain the CFI information to describe the characteristics of the
device. In order to enter the CFI Query mode, the system writes a three-byte sequence, same as prod-
uct ID entry command with 98H (CFI Query command) to address 555H in the last byte sequence.
Additionally, the system can use the one-byte sequence with 55H on the Address and 89H on the Data
Bus to enter the CFI Query mode. Once the device enters the CFI Query mode, the system can read
CFI data at the addresses given in Tables 8 through 10. The system must write the CFI Exit command
to return to Read mode from the CFI Query mode.
Product Identification
The Product Identification mode identifies the devices as the SST39VF1601C, SST39VF1602C, and
manufacturer as SST. This mode may be accessed software operations. Users may use the Software
Product Identification operation to identify the part (i.e., using the device ID) when using multiple man-
ufacturers in the same socket. For details, see Table 7 for software operation, Figure 14 for the Soft-
ware ID Entry and Read timing diagram and Figure 24 for the Software ID Entry command sequence
flowchart.
