Wide Vcc low-power flash memory

Why Wide Vcc? IoT edge devices need memory solutions that can continue to operate as the battery discharges and the supply voltage drops. Typical memory solutions have a limited operating voltage range. Adesto’s AT25FF offers Wide Vcc, as well as pin and functional compatibility to 1.8 V and 3.0 V devices. The AT25FF was designed with the performance and battery life challenges of next generation IoT in mind. It offers low-power operation as well as a high-speed SPI, dual and quad interface. This allows rapid transfer of code or data for fast booting, execute in place, AI, data transfer, or system configuration.
