Serial Flash Discovery Parameter Data
Serial Flash Discovery Parameter Data
The serial Flash discovery parameter (SFDP) provides a standard, consistent method to
describe serial Flash device functions and features using internal parameter tables. The
parameter tables can be interrogated by host system software, enabling adjustments to
accommodate divergent features from multiple vendors. The SFDP standard defines a
common parameter table that describes important device characteristics and serial ac-
cess methods used to read the parameter table data.
Micron's SFDP table information aligns with JEDEC-standard JESD216 for serial Flash
discoverable parameters. The latest JEDEC standard includes revision 1.6. Beginning
week 42 (2014), Micron's MT25Q production parts will include SFDP data that aligns
with revision 1.6.
Refer to JEDEC-standard JESD216B for a complete overview of the SFDP table defini-
tion.
Data in the SFDP tables is read by the READ SERIAL FLASH DISCOVERY PARAMETER
operation.
See Micron TN-25-06: Serial Flash Discovery Parameters for MT25Q Family for serial
Flash discovery parameter data.
