It uses a SPI interface with Quad I/O and QPI support, clocked at 80 MHz.
It is ROHS3 compliant. For dual-sourcing or higher-density requirements, the S25FS512SAGNFI011 (512 Mbit, 133 MHz) is a functional upgrade in the same FS-S family, but check the supply voltage and package compatibility.
Yes, it is ROHS3 compliant.
There is no direct pin-compatible second source listed. Within the same FS-S family, the S25FS512SAGNFI011 offers higher density (512 Mbit) and a faster 133 MHz clock, but check the supply voltage and package compatibility. For a 128 Mbit alternative at 3V, consider the S25FL128SAGNFI011 from the FL-S series, which runs at 133 MHz and 2.7V-3.6V supply.
