128 Mbit SPI Quad I/O NOR Flash — active, industrial-temp, 24-BGA
The S25FL128SAGBHVB03: The 24-BGA package (6x8 mm body) keeps the footprint compact for space-constrained designs like RF modules or compact controllers.
The 133 MHz clock rate with Quad I/O (four data lines) gives a peak read throughput around 66 MB/s — enough to feed a high-speed MCU or FPGA configuration engine without bottlenecking code execution. For designs that boot directly from NOR (XIP), the Quad I/O mode cuts the initial latency versus a two-line SPI.
The base product number S25FL128 covers a family of density and package variants, so if a future board revision needs a different package or temperature grade, the migration stays within the same memory controller setup.
Package and footprint — 24-BGA with a 6x8 mm body
The 24-ball BGA (supplier device package 24-BGA, 6x8 mm) is a fine-pitch array — typical ball pitch is 1.0 mm, which routes cleanly on a two-layer board with a via-in-pad if you keep the trace lengths short.
