64 Mbit NOR Flash with Quad SPI — what it fits
It communicates over a SPI interface with Quad I/O and QPI support, clocked at 108 MHz. The 2.7 V to 3.6 V supply range and -40°C to 105°C operating temperature make it a fit for industrial motor drives, outdoor telecom gear, and automotive engine-bay modules where the board sees extended heat. The 8-SOIC package (5.30 mm width) keeps the footprint small for space-constrained designs.
108 MHz clock and Quad I/O — throughput for code shadowing
The 108 MHz clock rate with Quad I/O mode delivers a sustained read throughput that supports execute-in-place (XIP) or fast code shadowing to RAM. For designs that boot from SPI Flash, the Quad I/O interface cuts the read latency compared to standard SPI — the controller reads four bits per clock instead of one. The QPI mode further reduces command overhead by using the same four lines for address and data.
Industrial temperature grade — where it runs
The 105°C ceiling is the die temperature, not just ambient — so factor in self-heating from the board. The 8-SOIC package has a standard footprint; reflow profile follows the JEDEC MSL level on the reel label. Store the reels dry — moisture-sensitive devices from a Tray shipment still need a dry-bake if the seal is broken.
The 64 Mbit density and Quad SPI interface are common across the FL-L family.
