AT25EU

Ultra-Low Energy SPI NOR Flash with Fast Erase

bird and chip

The AT25EU is verified with the world’s lowest power Bluetooth 5.1 System-on-Chip, Dialog’s SmartBond DA14530 and DA14531.

Dialog’s DA1453x BLE solutions bring down power consumption to microwatt levels, enabling long battery lifetime and the use of smaller and cheaper batteries.

The AT25EU ultra-low energy profile and Fast Erase performance perfectly complement the DA14530 and DA14531.

Energy vs Power

Batteries store energy. This energy is delivered as power up to a maximum rate and this means that the trend towards smaller size and batteries makes energy usage an important consideration in the device design.

POWER = Rate at which ENERGY is transferred  (Watts = Volts x Current)

Focusing on lower power is helpful, but it can come at the expense of longer task completion times which can drive up energy usage and impact the usability of the system battery.

ENERGY = Amount of POWER required to complete a task  (Joules = Volts x Current x Time)

The AT25EU focuses on achieving the lowest power consumption and the fastest operation in order to achieve the lowest energy.
