Lowest power Flash devices feature fast erase times
Family of ultra-low energy, fast read NOR Flash devices deliver significantly faster erase times and power-saving features to reduce energy consumption of IoT devices

Dialog Semiconductor has launched the AT25EU family of SPI NOR Flash devices, to support the development of power-conscious, size-constrained connected IoT devices. The AT25EU focuses on achieving the lowest power consumption and the fastest operation in order to achieve the lowest energy.

Lower total energy consumption without sacrificing performance is a key differentiation of the AT25EU product family when compared to existing SPI NOR Flash products. Offering industry-leading low-power high-speed read operation, the family also boasts significantly faster erase times at a fraction of the power.

For example, the 2-Mbit AT25EU0021A can perform a full-chip erase in under 10 ms while consuming less than 1 percent of the energy demanded by competing devices, which can take a full second, or longer, to perform the same operation. The ability to achieve faster, lower energy erase operations improves the efficiency of functions such as Over-the-Air updates (OTA), event tracking, and data logging activities.

“The breakthrough low-energy consumption and high-performance for SPI NOR Flash builds on Dialog’s commitment to improving performance while lowering the power and cost of IoT devices,” said Raphael Mehrbians, VP of Industrial Standard Products (ASSP) Business Unit. “The addition of the industry’s lowest energy Flash devices enhances Dialog’s already outstanding portfolio of ultra-low power BLE, Wi-Fi, and GreenPAK™ products.”
