Memory is one of the most important hardware components in any computing device. It stores data for quick access and manipulation. Memory components come in various forms and a variety of products are available in the market. One such device is the AT45DB161D-SU, which is a non-volatile memory IC specifically designed for data storage applications. It is widely used in applications such as automotive, avionics, medical, industrial, and consumer electronics. This article will discuss the application field and working principle of the AT45DB161D-SU.

AT45DB161D-SU Application Field

The AT45DB161D-SU is an Serial Peripheral Interface (SPI) compatible non-volatile memory IC that is designed to store data even when power is removed. It has a maximum storage capacity of 2 Mbit, or 2 million bits, which is equivalent to 262,144 bytes (256KB). This non-volatile memory device is designed to store data securely, even in the event of a power failure, making it ideal for applications that require the data to remain stable, even after power has been removed. The device is widely used in automotive, avionics, medical, industrial, and consumer electronics applications, due to its fast access time and ability to maintain a high level of data integrity even in harsh environments.

The AT45DB161D-SU is especially popular for use in automotive applications, where firmware is often required to be stored securely and with maximum reliability. It is also trusted for medical applications, where medical data needs to be reliably stored and readily accessible. In industrial applications, the device is used to store critical data that needs to be securely stored even in harsh environments. Similarly, the device is used to store critical data in avionics applications and data that needs to remain stable and secure in consumer electronics applications.

AT45DB161D-SU Working Principle

The AT45DB161D-SU is a SPI compatible non-volatile memory IC designed to store data reliably, even in the event of power failure. It has a maximum storage capacity of 2 million bits (256KB) and is organized into 2 banks of 128KB each. The device uses a 256-byte page size and offers an Endurer™ DataFlash® embedded memory, which ensures reliable data storage over extended periods of time, even in harsh environments.

The device has an SPI configuration that can operate at up to 20MHz. It also offers hardware support for the setup and execution of instruction sequences, allowing the host to access the on-chip memory arrays quickly and easily. It supports a wide range of commands that enables the memory to act as if it is actually hosting its own processor, allowing it to easily interface with other components.

Data can be written to the device quickly and easily using the Write command. It is also possible to use the Erase command to delete an entire page or specific parts of a page. The Read command can be used to retrieve data from the device. The device also supports a variety of other commands including Wake-up, Status Register, and Control Register.

Conclusion

The AT45DB161D-SU is a non-volatile memory IC specifically designed for data storage applications. It is widely used in automotive, avionics, medical, industrial, and consumer electronics applications due to its fast access time and ability to maintain a high level of data integrity even in harsh environments.
