Dialog Semiconductor Adds Industry's Lowest Power Flash Devices to its IoT Portfolio

Dialog Semiconductor AT25EU

The AT25EU product 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 announced the launch of the AT25EU family of SPI NOR Flash devices, to support the development of power-conscious, size-constrained connected 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 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 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 ultra-low energy Flash memory family also offers a variety of power-saving features including wide Vcc (1.65 V to 3.6 V) operation to extend the battery life as well as the 100 to 300 nA 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 1 Mbit and 2 Mbit configurations and generally available for sampling in the second quarter of 2021. Additional devices in this family are planned for up to 16 Mbits density.
