Product details

128 Mbit NOR flash with Quad SPI at 133 MHz

The S25FS128SAGNFI100: It uses the SPI interface with Quad I/O and QPI support, clocking at up to 133 MHz — the Quad I/O mode effectively quadruples the read throughput over a standard single-bit SPI bus, which matters when the MCU fetches code or logs data at speed. NOR flash retains data without power and supports random-access read, so it fits firmware storage, boot code, and parameter tables where execute-in-place (XIP) is needed.

Package and board-fit: 8-WSON with exposed pad

Housed in an 8-WDFN exposed pad package (8-WSON, 5x6 mm body), the S25FS128SAGNFI100 mounts on the surface. The 1.7 V minimum supply means the part stays within spec even when the 1.8 V rail droops under load — a common condition on battery-powered boards during radio transmission.

Frequently asked questions

What is the memory interface and clock speed of the S25FS128SAGNFI100?

It uses an SPI interface with Quad I/O and QPI support, running at up to 133 MHz. In Quad I/O mode, four data lines transfer simultaneously, giving an effective read throughput of 532 Mbps (133 MHz x 4 bits).

What supply voltage does the S25FS128SAGNFI100 require?

The operating supply range is 1.7 V to 2.0 V. It is designed for a nominal 1.8 V rail, common in low-power embedded systems, and tolerates droop down to 1.7 V without losing data integrity.
