Product details

133 MHz Quad-SPI — what the clock rate buys you

The Infineon S25FL128SAGBHIT00 is a 128 Mbit FL-S series NOR Flash with a Quad-SPI interface clocked at 133 MHz. That clock rate, combined with the four I/O lanes, gives you a sustained read throughput that keeps an external Flash from being the bottleneck in a cached MCU or FPGA configuration load. The 16M x 8 organization maps cleanly to byte-addressable firmware images.

24-ball BGA — rework and layout notes

Housed in a 24-ball TBGA with a 6x8 mm body. That is a fine-pitch BGA — the ball diameter and pitch are tight enough that you want a decent X-ray for post-reflow inspection. The footprint is standard for the FL-S 24-BGA, so a layout designed for the sibling S25FL128SAGBHI20 should accept this part without a board spin.

Frequently asked questions

Does S25FL128SAGBHIT00 support Quad SPI?

Yes. The memory interface is SPI - Quad I/O, meaning it uses four data lines for reads and writes. At 133 MHz clock, that gives you a practical read throughput well above a standard single-bit SPI part.

Is S25FL128SAGBHIT00 a direct replacement for S25FL128SAGBHI20?

The two parts share the same base product number S25FL128, same 128 Mbit density, same Quad-SPI interface, and same 24-TBGA package. The suffix difference typically indicates a temperature grade or minor revision variant. Pin-compatibility across the FL-S 24-BGA footprint is expected, but confirm the specific suffix differences against the latest datasheet before committing a board spin.
