The S25FL256SDPNFB003: It communicates over a Quad I/O SPI interface at up to 66 MHz.
This part comes in an 8-WDFN with exposed pad (supplier package 8-WSON, 6x8 mm).
The difference is the shipping medium: the S25FL256SDPNFB003 is supplied in Tape & Reel (TR), while the S25FL256SDPNFB001 ships in a different carrier (typically Tray or Tube). The silicon and package are identical — both are 8-WSON 6x8 mm, 256 Mbit, 66 MHz Quad-SPI NOR Flash. Choose the reel variant for automated pick-and-place lines.
Within the same FL-S family, the S25FL256SDPNFB001 is the same silicon in a different shipping carrier. For a pin-compatible alternative from another vendor, look for 256 Mbit Quad-SPI NOR Flash in an 8-WSON 6x8 mm package — the Macronix MX25L25645G and Winbond W25Q256JV are common cross-shop candidates, but verify the exact footprint and command set before substituting.
