32 Mbit NOR Flash with 108 MHz SPI Quad I/O
The S25FL132K0XMFV013: The Quad I/O protocol allows four data lines to transfer in parallel, quadrupling the read throughput over standard SPI — useful for shadowing code to RAM or streaming configuration data without stalling the host.
Industrial temperature grade and supply range
The write cycle time is 3 ms per word or page — a full 32 Mbit erase is not specified here, but the page program time sets the floor for firmware update latency.
Infineon lists this part as Obsolete. The date-code and marking should be laser-etched — verify font consistency against Infineon's plant marking standards before accepting a lot.
