The AT45DB321D-CU is an Integrated Circuit (IC) component that is widely used for storing and retrieving digital information. It is a Serial Peripheral Interface (SPI) Flash memory device manufactured by Adesto Technologies Corporation. Here is an overview of the key features of the AT45DB321D-CU:
1. Memory Capacity: The AT45DB321D-CU offers a total memory capacity of 32 Megabits (4 Megabytes). This storage capacity makes it suitable for applications that require medium-sized data storage.
2. Dual-Interface: This IC component supports both a Serial Peripheral Interface (SPI) bus and a standard DataFlash Parallel Interface. The dual-interface allows for flexible and convenient data communication between the microcontroller and the IC.
3. Page-Oriented Architecture: The AT45DB321D-CU employs a page-oriented architecture where the memory is divided into pages, each page being 264 bytes. The page-oriented architecture enables efficient programming and erasing of small data portions, reducing overhead and enhancing performance.
4. Continuous Read/Write Capability: This IC facilitates Continuous Read and Write operations, enabling the user to sequentially read and write multiple pages of data without the need to issue extra commands in between operations. This feature is particularly useful in streaming applications that require high-speed data transfers.
5. Sector Lockdown: The AT45DB321D-CU offers the ability to protect critical data by locking down specific sectors in the memory
