Overview

The SST25WF080BT-40E/NP is an 8Mbit Serial Flash memory IC designed for low-voltage systems operating between 1.65V and 1.95V. It utilizes high-performance SuperFlash technology to provide fast program and erase times with high reliability. This part features a 40 MHz SPI interface with Dual I/O support, making it suitable for applications requiring compact, low-power non-volatile storage.

Why Choose This Part

This device offers excellent power efficiency with a standby current of only 70uA and a run current of 10mA at 40MHz. Its 1.8V nominal operation aligns with modern low-voltage SoC and FPGA I/O banks, eliminating the need for level shifters. The 8-USON (2x3mm) package provides a very small footprint for space-constrained PCB designs.

Applications

Firmware Storage
Ideal for storing boot code and application firmware in mobile devices and battery-operated IoT sensors.
Data Logging
Used in low-power environmental monitors to store sensor data logs at high densities.
Wearable Electronics
The small USON package and low supply voltage make it appropriate for smartwatches and fitness trackers.
Portable Medical Devices
Provides reliable SLC storage for configuration parameters in portable diagnostic equipment.

Getting Started

To integrate this flash memory, ensure your SPI controller is configured for Mode 0 or Mode 3 operation. Developers can use standard SPI drivers within frameworks like Zephyr or Microchip Harmony, or interface directly via bit-banging or hardware SPI peripherals. Hardware designers should place a 0.1uF decoupling capacitor close to the VDD pin for stable high-frequency performance.
