Adesto Technologies Corporation, Inc. Memory AT25SF081-MHF-T

The AT25SF081-MHF-T is an 8-Mbit SPI serial flash memory device that operates with a supply voltage range of 2.3V to 3.6V. It supports dual and quad output read modes, achieving a maximum operating frequency of 104 MHz. The device features a flexible erase architecture, allowing for uniform block erases of 4 KB, 32 KB, and 64 KB, as well as full chip erase capabilities. Typical program and erase times are efficient, with a 0.7 ms page program time for 256 bytes and a 70 ms block erase time for 4 KB. The AT25SF081-MHF-T is designed for low power consumption, with a typical deep power-down current of 2 µA and a standby current of 10 µA. It has an endurance of 100,000 program/erase cycles and a data retention period of 20 years. The device is available in various package options, including an 8-pad ultra-thin DFN and an 8-lead SOIC, and complies with industrial temperature ranges from -40°C to +85°C. However, it is noted that this part is not recommended for new designs, with a suggestion to use the AT25SF081B instead.
