Adesto Technologies Corporation, Inc. Integrated Circuits (ICs) - Memory AT45DB641E-MHN-T

The AT45DB641E-MHN-T is a 64-Mbit DataFlash memory device from Quarktwin Technology Ltd., designed for use with a single supply voltage ranging from 1.7 V to 3.6 V. It features a Serial Peripheral Interface (SPI) that supports modes 0 and 3, with a maximum clock frequency of 85 MHz and a low-power read option up to 15 MHz. The device allows continuous read capability across the entire memory array and has a configurable page size of 256 or 264 bytes. This memory chip includes two independent SRAM data buffers, enabling data reception while reprogramming the main memory. It offers flexible programming options, including byte and page programming, as well as various erase options such as page, block, sector, and chip erase. The device is equipped with advanced data protection features, including individual sector protection and a one-time programmable security register. Power consumption is low, with typical currents of 400 nA in ultra-deep power-down mode and 25 µA in standby mode. The AT45DB641E-MHN-T has a minimum endurance of 100,000 program/erase cycles per page and a data retention period of 20 years. It is available in multiple packaging options, including an 8-pad ultra-thin DFN (5 x 6 x 0.6 mm) and complies with industrial temperature ranges.
