Adesto Technologies Corporation, Inc. Memory AT45DQ161-SSHF-B

The AT45DQ161-SSHF-B 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 security register. The AT45DQ161-SSHF-B is characterized by low power consumption, with typical active read current at 11mA and ultra-deep power-down current as low as 500nA. It is rated for a minimum of 100,000 program/erase cycles per page and has a data retention period of 20 years. The product is available in various package types, including an 8-lead SOIC and ultra-thin DFN and UBGA options, making it suitable for a wide range of commercial and industrial applications.
