Product details

128Mbit NOR Flash with Quad SPI at 108 MHz

The S25FL127SABNFV100 is a 128Mbit NOR Flash memory from Infineon's FL-S series, organised as 16M x 8 bits. It communicates over an SPI bus with Quad I/O support, clocking up to 108 MHz — Quad I/O mode effectively quadruples the read throughput over a standard SPI part, which matters when the MCU is code-shadowing from flash or logging sensor data at high rate.

Operates from 2.7V to 3.6V, making it a direct fit on a 3.3V rail with margin for ripple.

Housed in an 8-WDFN with exposed pad (8-WSON 5x6 mm). The 5x6 mm footprint is compact enough for space-constrained designs but still hand-solderable with a hot-air station.

Active production — no EOL watch needed

Infineon lists the S25FL127SABNFV100 as Active.

Frequently asked questions

Is S25FL127SABNFV100 compatible with 3.3V logic?

Yes. The supply voltage range is 2.7V to 3.6V, which covers a nominal 3.3V rail. All SPI signals are referenced to VCC, so a 3.3V MCU SPI port drives the part directly without level translation.
