256 Mbit NOR Flash with Quad-SPI — what it brings to the board
The Infineon S25FL256SAGBHVA03 is a 256 Mbit FL-S series NOR Flash memory organized as 32M x 8 bits. The memory is non-volatile, formatted as FLASH, and comes in a 24-TBGA surface-mount package (24-BGA, 8x6 mm).
133 MHz Quad-SPI — throughput for XIP and fast boot
The 133 MHz clock frequency on the Quad I/O interface delivers a theoretical read throughput of 532 Mbps (133 MHz x 4 data lines). That is enough to support execute-in-place (XIP) from Flash for many MCUs and SoCs, eliminating the need to shadow code into RAM. For firmware updates, the Quad-SPI bus reduces the time to write a 32 MB image compared to standard SPI. The interface is backward-compatible with standard SPI, so it drops into existing SPI controllers that support Quad mode.
The 105°C ceiling is above the typical 85°C industrial limit, giving headroom for designs that run hot or sit near a power stage. Storage temperature exceeds this range, but the operating spec is what governs reliability under load.
The FL-S series has broad industry adoption, so supply continuity through independent distribution is stable. If you are qualifying this for a new design, there is no lifecycle-driven urgency to find a second source today.
Package and footprint — 24-BGA (8x6 mm)
The 24-TBGA package measures 8 mm x 6 mm (body), with a 0.8 mm ball pitch typical for this density. It is a surface-mount BGA that requires a solder-paste stencil and reflow profile per the manufacturer's recommendations.
