512 Mbit NOR Flash with Quad SPI — density and speed for code-shadowing
The Infineon S25FS512SAGBHI210 is a 512 Mbit NOR Flash memory organized as 64M x 8 bits, accessed through a SPI Quad I/O interface that supports both standard SPI and QPI protocols at a 133 MHz clock frequency.
Package and board-fit — 24-ball BGA, 8x6 mm
Housed in a 24-ball TBGA (8x6 mm body), the S25FS512SAGBHI210 requires a 0.80 mm ball pitch layout — the footprint is compact enough for space-constrained designs but still hand-solderable with a rework station. The 1.7 V to 2 V supply rail means this part runs from a 1.8 V nominal rail, common in low-power SoC and FPGA systems.
