Automotive-grade 512 Mbit NOR Flash with Quad SPI
The S25FS512SFABHB210: It uses a SPI Quad I/O and QPI interface running at 133 MHz, giving you a sustained read throughput that keeps a Cortex-M7 or similar high-end MCU fed without wait-state stalls on code execution. The 64M x 8 organization maps cleanly to a linear address space for both code shadowing and data logging.
Housed in a 24-ball TBGA (8x6 mm body), the S25FS512SFABHB210 requires a standard BGA reflow profile with a peak temperature around 245°C. The 0.8 mm ball pitch is manageable on a 4-layer board; route the SPI signals (CS, SCK, SI/SO, WP#, HOLD#) with matched trace lengths to keep setup/hold margins at 133 MHz. X-ray inspection after reflow verifies solder joint integrity; the 24 balls are arranged in a 4x6 grid with no center thermal pad, so visual inspection is straightforward.
Lifecycle and compliance
For new designs, this part is a safe choice — no imminent obsolescence risk.
