The Infineon S25FL256LAGNFV010 is a 256 Mbit SPI NOR Flash from the FL-L family, organized as 32M x 8 bits.
ROHS3 compliant and free of the six restricted substances plus the four phthalates, which clears it for EU and California regulatory filing without an exemption review.
Package and footprint — the exposed pad matters
The 8-WSON (6x8 mm) package has a large exposed pad on the bottom. The datasheet's recommended land pattern calls for a central thermal pad with several vias to the ground plane. Without those vias, thermal resistance rises measurably — the part can still run, but the case temperature under sustained 133 MHz reads will be higher. The tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel, so factor that into pick-and-place feeder setup if you are using a reel feeder.
