Fusion XE/Fusion XV
AT25XE/XV Series | Ultra-low Energy Serial Flash
Code Storage Solutions
for the Connected World
Wide-voltage range, ultra-low energy memory technology enabling next generation solutions
for consumer, communication, mobile and industrial applications
As modern electronics evolve, the need for new low density,
low energy code storage memory devices has emerged to
meet the needs of mobile, wearable, and industrial
applications in a connected world.
The Adesto® Fusion AT25XE/XV Series are families of highly
optimized ultra-low energy serial interface Flash memory
devices designed for use in a wide variety of high-volume
low energy consumer and industrial applications.
Targeted to meet the needs of today's connected
applications in the Internet of Things, its granular Page
Erase and Block Erase architecture allows the memory space
to be used much more efficiently supporting data storage
and over-the-air updates. The resulting improvement to
software efficiency allows reduced CPU / MCU overheads to
further reduce system energy usage.

Description
The Adesto® AT25XE/XV series is designed for use in a wide variety of high-volume consumer based applications in which
program code is shadowed from Flash memory into embedded or external RAM for execution. The XE/XV families consume
ultra-low energy Read and Erase currents enabling highly-energy conscious designs, perfectly suited to the Internet of
Things and wearable electronics.
With a wide voltage range of 1.65V to 3.6V or 1.65V to 4.4V the new AT25XE/XV Serial Flash families not only use less
power during standard operation but also offer designers the ability to operate over the full Vcc range of the battery --
maximizing on-board energy reserves and eliminating the need for external regulators. The ultra-deep power down mode
allows devices to function with a class leading standby current of 200 nanoamps, an order of magnitude improvement over
standby modes available today. The devices also include a page erase feature for faster programming and updates.
