The Infineon S25FL512SAGBHI213 is a 512 Mbit NOR flash from the FL-S family, organized as 64M x 8, communicating over an SPI Quad I/O interface clocked at 133 MHz. That clock rate means the part can sustain a read throughput high enough to support execute-in-place (XIP) for a modern MCU or FPGA configuration image without stalling the core.
24-ball BGA — footprint and reflow considerations
The solder-ball layout demands a clean PCB land pattern and a reflow profile that matches the JEDEC MSL level for this package. The compact footprint saves board area, but the BGA makes post-assembly inspection and rework harder than a QFP — something to factor into the manufacturing yield plan.
For a production BOM, this reduces the supply-chain risk of a sudden discontinuation.
