That means no last-time-buy window remains open through the factory channel. For a production board or a repair that still needs this exact part number, the only path is the independent surplus and broker market — which is exactly the channel this listing serves.
256 Mbit SPI NOR Flash with Quad I/O
This is a 256 Mbit NOR Flash memory from Infineon's FL-L series, organized as 32M x 8 bits. It communicates over a SPI bus with Quad I/O and QPI support, clocked at 133 MHz. The 2.7 V to 3.6 V supply range and -40°C to 105°C operating temperature make it suitable for industrial environments where the board sees heat but not extreme under-hood conditions.
133 MHz clock — what it buys you on the bus
At 133 MHz with Quad I/O enabled, this part delivers a sustained read throughput that keeps a Cortex-M or RISC-V MCU fed during execute-in-place (XIP) operation. The interface is SPI, not parallel NOR, so the pin count stays low — 16-SOIC — but the trade-off is that write and erase cycles are slower than a parallel bus part. For code shadowing or data logging where the density fits, the 133 MHz Quad I/O is the right trade.
