Memory

The AT45DB081B-RI memory is a common choice for embedded applications that require non-volatile memory. It is a Serial Peripheral Interface (SPI) device that is used to store data and program code. The AT45DB081B-RI is Flash memory manufactured by Atmel Corporation and features a storage capacity of 8 Megabit (1 MByte). It is also available in larger capacities, including 16 Megabit (2 MByte), 32 Megabit (4 MByte), and 64 Megabit (8 MByte).

Application Field

The AT45DB081B-RI is primarily used as an embedded system for storing application files, firmware, and data. It is also used in many other applications, including mobile phones, consumer electronics, automotive industry, aerospace, and medical equipment. It can be used in places where power management is particularly important, such as in space and satellite applications. It is also often used for data logging, industrial automation, and data protection applications.

Working Principle

The AT45DB081B-RI is composed of two memory systems—a static RAM and a Flash memory. The static RAM is used for buffering data, while the Flash memory contains the primary data. The Flash memory is divided into sectors and pages, which are the basic units of organization. A page can store up to 256 bytes of data, while a sector can comprise multiple pages. Data is written to or read from the Flash memory by executing several commands, such as read, write, erase, or program.

The AT45DB081B-RI also includes a built-in controller, which manages the data flow between the static RAM and the Flash memory. The controller implements several features, including an automatic address increment, data auto-execution, and a power down mode. It also ensures data integrity by performing checksum calculations on all data stored in the Flash memory.

The AT45DB081B-RI is a powerful and reliable memory choice for embedded systems. It is highly efficient and cost-effective, making it an ideal component for various applications. It is also available in a variety of sizes and capacities, which makes it a suitable memory solution for any embedded system.
