256Mbit SPI NOR flash at 133 MHz — firmware storage and boot-read
The S25FL256SAGBHIA10 is a 256Mbit SPI NOR flash from Infineon's FL-S series, organized as 32M x 8 bits. It supports SPI and Quad I/O interfaces at a clock frequency of 133 MHz, which translates to a sustained read throughput that can keep a Cortex-M or RISC-V core fed during execute-in-place (XIP) boot without wait-state bottlenecks.
BGA footprint — rework station required
The 24-BGA (8x6) supplier package means the ball array is on a 0.8 mm pitch typical for this density. A hot-air reflow station with a preheat plate is the minimum for removal; a profile-matched stencil and paste printer are needed for production rework. The tray packaging is the standard delivery format for BGA parts — no tape-and-reel, so pick-and-place lines need a tray feeder or a tube-to-tape conversion step.
