Adesto Technologies Corporation, Inc. Integrated Circuits (ICs) - Memory AT45DB041E-SHNHC-T

The AT45DB041E-SHNHC-T is a 4-Mbit SPI serial flash memory device from Quarktwin Technology Ltd. It operates with a single supply voltage ranging from 1.65 V to 3.6 V and supports SPI modes 0 and 3, with a maximum clock frequency of 85 MHz. The device features continuous read capability across the entire memory array and offers a low-power read option at 15 MHz. This memory chip includes user-configurable page sizes of 256 bytes (default) or 264 bytes, with two independent SRAM data buffers that facilitate data reception while reprogramming the main memory. It supports various programming and erasing options, including byte/page programming, page erase, block erase, sector erase, and chip erase, with a program/erase endurance of 100,000 cycles at -40 ¬8C to +85 ¬8C and 10,000 cycles at -40 ¬8C to +125 ¬8C. The device incorporates advanced data protection features, including individual sector protection and a one-time programmable security register. It also boasts low power consumption, with typical currents of 400 nA in ultra-deep power-down mode and 25 ¬µA in standby mode. The AT45DB041E-SHNHC-T is available in an 8-lead SOIC package and is compliant with RoHS standards. This product is suitable for applications requiring reliable, high-speed data storage with robust data protection features.
