The Infineon S25FL064LABNFI011 is a 64 Mbit FLASH - NOR memory device from the FL-L series, organized as 8M x 8 bits. The supply voltage range is 2.7 V to 3.6 V, and the operating temperature spans -40°C to 85°C, covering industrial and outdoor telecom environments. It comes in an 8-WSON (5x6 mm) package for surface-mount assembly. This part is typically used for code shadowing, firmware storage, and data logging in embedded systems, industrial controllers, and networking equipment where fast read throughput and a small footprint are required.
108 MHz Quad SPI — what the clock rate means for your bus
The 108 MHz clock frequency, combined with Quad I/O mode, delivers a sustained read throughput that keeps a Cortex-M or RISC-V core fed without wait states on a moderate-speed SPI bus. If your design currently uses a single-bit SPI NOR Flash at lower clock rates, moving to this part can reduce firmware load times and free up CPU cycles. The QPI mode further reduces command overhead by allowing opcode and address cycles over four lines — useful when the host controller supports it.
