The S25FL064LABMFV001 is a 64 Mbit NOR Flash from Infineon's FL-L series, built for code shadowing, firmware storage, and data logging in embedded systems that need fast read throughput. The 108 MHz clock rate over the Quad I/O interface delivers a sustained read bandwidth that keeps a Cortex-M or RISC-V core fed during execute-in-place (XIP) boot without wait-state stalls.
Memory organization and interface
Organised as 8M x 8 bits, the array is accessed through a SPI bus that supports standard, Dual I/O, Quad I/O, and QPI protocols. Quad I/O mode reduces the pin count for read operations while still moving data at 108 MHz, which is the practical ceiling for most MCU SPI peripherals without a dedicated QSPI controller.
Infineon lists this part as Active.
