Read SFDP Register (5Ah)
The S25FL016K features a 256-Byte Serial Flash Discoverable Parameter (SFDP) register that contains
information about devices operational capability such as available commands, timing and other features. The
SFDP parameters are stored in one or more Parameter Identification (PID) tables. Currently only one PID
table is specified but more may be added in the future. The Read SFDP Register instruction is compatible
with the SFDP standard initially established in 2010 for PC and other applications.
The Read SFDP instruction is initiated by driving the CS# pin low and shifting the instruction code “5Ah”
followed by a 24-bit address (A23-A0)(1) into the SI pin. Eight “dummy” clocks are also required before the
SFDP register contents are shifted out on the falling edge of the 40th CLK with most significant bit (MSB) first
as shown in
table.
Note: A23-A8 = 0; A7-A0 are used to define the starting byte address for the 256-Byte SFDP Register.
