Product details

The 2.7 V to 3.6 V supply range and -40°C to 85°C industrial temperature grade suit it for embedded firmware storage, boot code, parameter logging, and over-the-air update staging in industrial controllers, IoT gateways, networking gear, and automotive infotainment (non-safety) modules. The 8-USON package with exposed pad (4x4 mm) keeps the footprint small for space-constrained PCBs.

Quad SPI and QPI — what the interface modes mean for throughput

Quad I/O transfers four bits per clock. At 108 MHz, the effective read throughput increases accordingly.

The S25FL064LABNFI040 is listed as Active. ROHS3 compliant. The base product number is S25FL064.

Frequently asked questions

Does S25FL064LABNFI040 support quad SPI?

Yes, it supports SPI - Quad I/O and QPI modes, enabling four-bit-wide data transfers at up to 108 MHz.

Is S25FL064LABNFI040 compatible with standard SPI?

Yes, it is backward-compatible with standard single-bit SPI, and also supports Quad I/O and QPI for higher throughput when the host controller supports those modes.

What is the closest functional equivalent for S25FL064LABNFI040?

The S25FL064LABNFI010 is functionally identical — same 64 Mbit density, 108 MHz Quad SPI, 2.7-3.6V supply, and -40°C to 85°C range — but packaged in a different tray variant. The S25FL064LABNFV010 extends the temperature range to -40°C to 105°C. The S25FL064LABNFI043 is the tape-and-reel version of the same die and package.
