Adesto Lowers Power In Its Latest Flash Memory Devices

March 5, 2019 Rich Nass

I’m often impressed with the memory vendors, as it seems like they continue to innovate in a space that always seems like it’s out of room for innovations, except on the manufacturing side. Adesto Technologies was the latest memory vendor to hit my radar, this time at the recent Embedded World show in Nuremberg, Germany.

Adesto’s FusionHD non-volatile memories (NVMs) are aimed at consumer and industrial IoT Edge devices. It delivers low power consumption, fast data transfer and robust, high-reliability operation. Unlike standard flash devices, FusionHD incorporates a small-page erase and write architecture that makes saving small packets of data quick and efficient. It also allows large data packets to be saved and accessed using minimal CPU clock cycles, reducing processing time and battery consumption.

The latest parts offer 32 Mbits of storage and operating voltage levels of 1.7 to 3.6 V. Another interesting feature is the ability to interrupt the host MCU when needed. Samples of FusionHD AT25XE321B are available now.

FusionHD supports the new Serial Flash Reset Signaling Protocol (JESD252) and the latest version of the SFDP standard (JESD216D). These standards make it easier for system designers to deliver smarter, more efficient and user-friendly devices.
