8 Mbit Quad-SPI flash for 1.8V sensor nodes
The SST26WF080BT-104I/NP is an 8 Mbit (1M x 8) non-volatile flash memory from Microchip's SST26 SQI® series, communicating over SPI with Quad I/O at up to 104 MHz. Its 1.65V–1.95V supply range directly matches a 1.8V logic rail or single-cell Li-ion battery, making it a natural fit for battery-powered sensor modules, portable instruments, and IoT endpoints where every millivolt of headroom matters. The 8-USON (2x3 mm) package with exposed pad keeps the footprint small — roughly half the area of an SOIC-8 — while the industrial temperature range (-40°C to 85°C) covers outdoor enclosures and factory-floor environments without qualification overhead.
Supply voltage and interface: why 1.65V minimum matters
The 1.65V minimum supply is the key differentiator from older 2.7V–3.6V flash parts like the SST25VF016B (2.7V min) or SST25VF010A (2.7V min). In a 1.8V system with a ±5% rail, the SST26WF080BT-104I/NP operates reliably down to 1.71V, while a 2.7V-min part would need a separate regulator or boost converter — adding cost and board area. Quad I/O (SPI with four data lines) at 104 MHz delivers effective throughput well above a single-bit SPI bus at the same clock, reducing firmware-update time and freeing the MCU for other tasks.
