256 Mbit NOR Flash with 133 MHz Quad SPI
The S25FL256LAGBHN033 is a 256 Mbit NOR Flash memory from Infineon's FL-L series, organised as 32M x8 bits. It communicates over a SPI interface supporting Quad I/O and QPI protocols at a 133 MHz clock frequency, which gives a read throughput ceiling of 532 Mbit/s in quad mode — enough to shadow firmware into RAM or stream configuration data without stalling the host controller. The memory is non-volatile and operates from a single 2.7V to 3.6V supply, making it a direct fit for 3.3V logic domains common in MCU and SoC designs.
Package and footprint — BGA-24 rework considerations
The supplier device package is 24-BGA (6x8 mm) — confirm the land pattern matches the Infineon application note for the FL-L family.
Obsolete — sourcing for existing BOM lines
Infineon lists the S25FL256LAGBHN033 as Obsolete. For designs already in production, the part can be sourced through independent distribution on a per-RFQ basis. The base product number S25FL256 may help identify alternative speed grades or temperature variants within the FL-L family that are still active — check the Infineon product selector for current ordering codes.
