AT45DB081E-SHN-T – ADESTO

The AT45DB081E-SHN-T is a serial-interface Flash memory device from Analog Devices, featuring a capacity of 8 Mbits (1024 Kbytes) organized as 4096 pages of 256 bytes each. It utilizes a standard SPI interface, supporting SPI modes 0 and 3, enabling communication with a host microcontroller. The device operates at a maximum clock frequency of 85 MHz, facilitating rapid data transfer. Internally, the AT45DB081E incorporates two SRAM data buffers, each 256 bytes in size, which allow for continuous data streaming and efficient program/erase operations. The architecture supports sequential read operations, page program, block erase, and chip erase functions. The device operates from a supply voltage range of 2.7V to 3.6V. Specified operating temperature range is -40°C to +85°C. The AT45DB081E-SHN-T is housed in an 8-SOIC package, making it suitable for surface-mount assembly in embedded systems requiring non-volatile memory. Power consumption is dependent on the operating mode, with standby current typically in the microampere range.
