85 MHz SPI — timing margin for the host
The 85 MHz SPI clock is the headline speed. At this rate the serial interface can sustain read throughput roughly in the tens of megabytes per second, depending on the host's SPI peripheral and the command overhead. That is fast enough for direct code execution (XiP) in many MCUs and for FPGA configuration loading without stalling the boot sequence. The page write cycle takes 5 ms, and the byte/word write takes 8 µs — the page time dominates when you are filling a full page buffer.
Industrial temperature and active lifecycle
The part is rated for -40°C to +85°C, which covers outdoor telecom cabinets, factory-floor controllers, and automotive cabin modules. It is listed as Active in production, so there is no near-term LTB or obsolescence risk for new designs. ROHS3 compliant, no exemption issues for EU markets.
Package and mounting
The 8-VDFN (6x8 mm) exposed-pad package is a surface-mount footprint. The exposed pad must be soldered to a ground plane — it is the primary thermal path and also provides a low-impedance ground connection. The part is supplied on Tape & Reel (also available as Cut Tape), which is the standard format for automated pick-and-place assembly. No through-hole option exists for this density.
