Identification Commands
Reset
Reserved
Read Identification - REMS (Read_ID or REMS 90h)
There is a command to reset to the default conditions present after power on to the device. There is a
command to reset (exit from) the Enhanced Performance Read Modes.
Some instructions are reserved for future use. In this generation of the S25FL512S some of these command
instructions may be unused and not affect device operation, some may have undefined results.
Some commands are reserved to ensure that a legacy or alternate source device command is allowed
without affect. This allows legacy software to issue some commands that are not relevant for the current
generation S25FL512S device with the assurance these commands do not cause some unexpected action.
Some commands are reserved for use in special versions of the FL-S not addressed by this document or for
a future generation. This allows new host memory controller designs to plan the flexibility to issue these
command instructions. The command format is defined if known at the time this document revision is
published.
The READ_ID command identifies the Device Manufacturer ID and the Device ID. The command is also
referred to as Read Electronic Manufacturer and device Signature (REMS). READ-ID (REMS) is only
supported for backward compatibility and should not be used for new software designs. New software
designs should instead make use of the RDID command.
The command is initiated by shifting on SI the instruction code “90h” followed by a 24-bit address of 00000h.
Following this, the Manufacturer ID and the Device ID are shifted out on SO starting at the falling edge of SCK
after address. The Manufacturer ID and the Device ID are always shifted out with the MSB first. If the 24-bit
address is set to 000001h, then the Device ID is read out first followed by the Manufacturer ID. The
Manufacturer ID and Device ID output data toggles between address 000000H and 000001H until terminated
by a low to high transition on CS# input. The maximum clock frequency for the READ_ID command is
133 MHz.
