Serial Flash Discovery Parameters for MT25Q Family

TN-25-06: Serial Flash Discovery Parameters for MT25Q Family
Introduction
Technical Note
SFDP for MT25Q Family
Introduction
The serial Flash discoverable parameter (SFDP) standard enables a consistent method
to describe serial Flash device function and feature capabilities in internal parameter
tables. Host system software can query the standard parameter tables and enable adjustments to accommodate features that vary from one vendor to another.
The SFDP standard defines a common parameter table that describes important device
characteristics and serial access 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. Micron's
MT25Q production parts, beginning week 42 (2014), will include SFDP data that aligns
with revision 1.6.
Refer to JEDEC-standard JESD216B for a complete overview of the SFDP table definition. Refer to any MT25Q family data sheet for conditions not specified here.
