AT45DB161E-SHD-T

The AT45DB161E-SHD-T is a serial flash memory device manufactured by Adesto Technologies, designed for embedded systems and industrial applications requiring reliable, non-volatile data storage. This component belongs to the AT45DB series of SPI-compatible flash memories, which are widely used in applications where code storage, configuration data retention, and logging functionality are essential. Serial flash memories like this part are fundamental building blocks in modern electronics, serving as the primary storage medium for microcontroller firmware, application code, and critical system parameters. The AT45DB series is particularly popular in industrial control systems, IoT devices, automotive electronics, medical instrumentation, and consumer electronics where cost-effective, compact storage solutions are needed alongside microprocessor units. The AT45DB161E variant is a mid-range capacity device within Adesto's flash portfolio, making it suitable for applications requiring moderate data storage without the overhead and power consumption of larger memory solutions. The SHD packaging designation indicates this part uses a small outline package format, which allows for efficient PCB layout and reduced board real estate—a practical advantage in space-constrained industrial designs. Key reasons engineers specify the AT45DB161E-SHD-T include its proven reliability in industrial temperature ranges, compatibility with standard SPI communication protocols that integrate easily with common microcontroller interfaces, and Adesto's reputation for manufacturing robust memory solutions. The part's integration into established design ecosystems means development teams can leverage existing firmware libraries, reference designs, and application notes, reducing time-to-market. This flash memory type is particularly well-suited for applications where data persistence through power cycles is critical, such as data logging systems, parameter storage in industrial automation controllers, firmware updates in field-deployed equipment, and configuration retention in smart sensors. The serial interface approach simplifies board design compared to parallel memory alternatives, requiring fewer PCB traces and GPIO connections from the host processor. Adesto's AT45DB series has established a track record across decades of industrial deployment, which makes it a conservative, low-risk choice for engineers designing systems expected to operate reliably over extended periods in challenging environments. When specified alongside appropriate supporting circuitry and firmware protocols, the AT45DB161E-SHD-T provides dependable non-volatile storage for applications where data integrity and long-term availability are non-negotiable requirements.
