256 Mbit SPI NOR flash — industrial temperature, Quad I/O interface
The S25FL256LAGBHV033 is a 256 Mbit SPI NOR flash from the FL-L series, organized as 32M x 8 bits. It supports Quad I/O and QPI interfaces at a clock frequency of 133 MHz, delivering read throughput suitable for code shadowing and data logging in embedded systems.
Obsolete — last-time-buy sourcing through independent channels
For sustainment programs — medical equipment, defense systems, or long-life industrial controllers that already carry this part on the BOM — the only sourcing path is through independent distribution. Inventory is lot-specific and confirmed at RFQ; no pin-compatible drop-in replacement is documented from Infineon.
Package and board-fit — 24-TBGA rework considerations
For PCB layout, the 24-ball array with 0.80 mm pitch allows fan-out on two layers with via-in-pad if the board stack-up supports it. Decoupling capacitors should be placed within 2 mm of the supply balls to minimize inductance at 133 MHz switching.
