Low power flash devices in Dialog Semi’s IoT portfolio

Lower total energy consumption without sacrificing performance is a key differentiation of the AT25EU product family when compared to existing SPI NOR Flash solutions. 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 2Mbit AT25EU0021A can perform a full-chip erase in under 10ms while consuming less than one 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.”

The ultra-low energy Flash memory family also offers a variety of power-saving features including wide Vcc (1.65 to 3.6V) operation to extend the battery life as well as the 100 to 300nA deep power-down mode to conserve energy when the product is not in use.

The exceptional erase time, in conjunction with the low-power high-speed operation, will drastically reduce the total energy consumed in any system. This makes it the ideal solution to help extend the operational time of small battery powered IoT devices.

The first of the AT25EU product family of devices will be offered in 1Mbit and 2Mbit configurations and generally available for sampling in the second quarter of 2021. Additional devices in this family are planned for up to 16Mbits density.
