256 Mbit NOR Flash with Quad SPI — 66 MHz speed bin in the FL-L family
The Infineon S25FL256LDPNFI010 is a 256 Mbit NOR Flash memory from the FL-L series, organized as 32M x 8 bits.
It is not qualified for extended automotive (125°C) or downhole environments. If your BOM requires the wider -40°C to 125°C range, the sibling S25FL256LAGMFN000 in the same FL-L family is the correct pick — same 256 Mbit density, same Quad SPI interface, but rated for the full automotive temperature span.
Package and PCB layout note
Housed in an 8-WSON (6x8 mm) exposed-pad package, the S25FL256LDPNFI010 requires a thermal pad on the PCB for proper solder joint reliability and heat transfer. The pad must be connected to ground plane with several vias to avoid delamination during reflow.
