Applications
The SST26WF080BT-104I/SN is used for firmware code storage and non-volatile data logging in ultra-low-power IoT devices, wearables, and wireless sensor nodes where the 1.8 V supply voltage directly interfaces with modern low-voltage MCUs and SoCs without level shifting. Its 104 MHz quad SPI interface enables fast execute-in-place or shadow loading for embedded applications requiring boot times under 100 ms. The 8-pin SOIC package fits standard footprints on compact PCBs alongside NB-IoT, BLE, or Zigbee SoCs in smart metering and industrial remote monitoring designs.

Frequently Asked Questions
What interface protocol does SST26WF080BT-104I/SN use, and what is the maximum data transfer rate?
The SST26WF080BT-104I/SN supports the SQI (quad SPI) protocol with 4 data lines simultaneously active, achieving up to 104 MHz clock frequency for an effective throughput of approximately 52 MB/s in quad-read mode. This is roughly 4 times faster than standard single-line SPI at the same clock rate, enabling a 1 MB firmware image to transfer in under 20 ms for fast boot applications.
How long can SST26WF080BT-104I/SN retain stored data, and what endurance does it provide for frequent write applications?
The SST26WF080BT-104I/SN guarantees 100-year data retention at 85 °C and 100,000 program/erase cycles per sector. For a device logging 10 events per hour, cycling each 4 KB sector evenly, the 100,000-cycle endurance would support over 11 years of continuous logging before any sector wear-out, making it suitable for industrial sensors and meters with decade-long deployment lifetimes.
At what supply voltage does SST26WF080BT-104I/SN operate, and which MCU families does it directly interface with?
The SST26WF080BT-104I/SN operates from 1.7 V to 1.95 V, aligning directly with 1.8 V I/O logic of popular low-power SoCs and MCUs such as STM32L0, nRF52840, PIC32MZ DA, and ESP32 series devices. This native 1.8 V compatibility eliminates level-shifting components, reducing BOM complexity and lowering total standby power of the storage subsystem below 10 µA.
How does SST26WF080BT-104I/SN write protection work, and why is it important for firmware security?
The SST26WF080BT-104I/SN implements individual block protection with a dedicated non-volatile block protection register controlling write access to each 8 KB or 32 KB sector independently. Hardware write protection can be engaged via a dedicated /WP pin for physical security, preventing unauthorized firmware modification even in the presence of software bugs or malicious code, an important requirement for IoT devices that must pass security certification standards such as IEC 62443 or PSA Certified.
