64 Mbit SPI NOR flash, 108 MHz quad-I/O, automotive temp range
The S25FL064LABMFB011 is a 64 Mbit SPI NOR flash from Infineon's Automotive FL-L series, organized as 8M x 8 bits. It communicates over an SPI bus with Quad I/O and QPI support at a clock frequency up to 108 MHz, giving the firmware engineer a fast read path for code shadowing or data logging. Supply voltage spans 2.7V to 3.6V, and the part is specified for -40°C to 105°C ambient — the industrial-plus band that covers under-hood electronics and outdoor base stations without a heat sink.
Package and footprint — 8-SOIC wide-body
Housed in an 8-SOIC wide-body package (0.209-inch body width, 5.30 mm), the S25FL064LABMFB011 is a surface-mount device that fits a standard 150-mil SOIC footprint. The supplier device package is 8-SOIC, and the base product number is S25FL064, so the same PCB layout serves the full FL-L family across temperature grades. Delivery is in tube packaging — not tape-and-reel — which is typical for engineering samples or low-volume production runs. If your pick-and-place line expects reel, the tape-and-reel variant (S25FL064LABMFM013) is the direct drop-in.
Lifecycle and compliance — active, ROHS3, AEC-Q100
For a BOM cost engineer, this part carries no single-source risk within the FL-L family: the 85°C variant (S25FL064LABMFI001) and the 125°C variant (S25FL064LABMFM000) share the same die and footprint, so a second-source swap is a one-line BOM change without a board spin.
Sourcing and availability — quoted to order
Sourced through independent distribution channels, the S25FL064LABMFB011 is quoted to order against an RFQ. For a procurement buyer comparing the 105°C variant (this part) against the 85°C S25FL064LABMFI001, the only parametric difference is the temperature ceiling — the same 108 MHz clock, 8M x 8 organization, and 8-SOIC wide-body package. If your ambient stays below 85°C, the -MFI001 is a cost-effective alternative; above that, this -MFB011 is the correct fit.
