Adesto Technologies Corporation, Inc. Memory AT45DQ161-SSHF2B-T

The AT45DQ161-SSHF2B-T is a 16-Mbit serial Flash memory device from Quarktwin Technology Ltd., designed for applications requiring high-speed data access. It operates on a single supply voltage ranging from 2.3V to 3.6V and supports SPI communication, including Dual-I/O and Quad-I/O modes, with maximum clock frequencies of 85MHz. The memory is organized into 4,096 pages of either 512 or 528 bytes, and features two independent SRAM buffers that facilitate data reception while reprogramming the main memory. This device offers flexible programming and erasing options, including page, block, sector, and chip erase capabilities. It also includes advanced data protection features, such as individual sector protection and a One-Time Programmable (OTP) security register. The AT45DQ161 is suitable for a wide range of applications, including digital voice and image storage, and is optimized for low power consumption, with typical active read current at 11mA and deep power-down current as low as 3µA. It is available in multiple package options, including 8-lead SOIC and ultra-thin DFN, and complies with RoHS standards. The device is rated for 100,000 program/erase cycles per page and has a data retention period of 20 years, making it a reliable choice for industrial applications.
