AT25DF512C-SSHN-T Integrated Circuits (ICs)

The AT25DF512C-SSHN-T is a 3.3V, 8 Mb, SPI-Bus Serial Flash memory, which includes a Device ID and ultrasecure software functions. It is a non-volatile, non-volatile memory that provides fast access time, high performance and energy-efficient programming in systems such as access control, system logs and asset tracking. Its memory organization consists of 256K x 8 bits of data organized in 16 sectors of 16,384 x 8 bytes each.

Application Field

The AT25DF512C-SSHN-T memory is used in a variety of applications due to its reliable fast access, high performance, and energy-efficient programming. Areas of application include embedded systems, access control, secure code execution, and system logging. Embedded systems operate these devices in order to provide control and storing data. Access control applications may use this device for authentication and encryption of data. On the other hand, secure code execution harnesses the power of the device for secure storage of code and/or data. System logging requires the efficient programming of this device to store system events or other information.

Working Principle and Features

The AT25DF512C-SSHN-T memory works by executing a series of commands to access or modify data stored in the memory. The commands include writing, erasing, or reading data from or to the memory. Upon receiving power, the device configures itself to be ready for any operation. The commands are transmitted over the SPI-Bus interface and the device transmits or receives data accordingly.

The AT25DF512C-SSHN-T memory features Data Polling and Toggle Bits for software enabled additional protection functions, as well as support for the proprietary “Security and Protection System”. These features can be used in secure systems to detect unintended or malicious attempts to read or write to the memory. Additionally, this device supports external chip erasure, which allows the entire memory to be erased in a single erase block. This is important in security systems where it is necessary to erase the entire memory in order to prevent unauthorized access.

The AT25DF512C-SSHN-T device also includes an internal Block Protection feature that allows the user to configure each sector with a specific block protection setting; these settings are defined as read-only, write-only, both read and write, and no access. This flexibility allows the user to create secure systems with as much or as little protection as needed.

Additionally, the AT25DF512C-SSHN-T device integrates an ultra-secure background operational logic, which verifies conditions before executing any operation on the memory. This includes erasing a memory block or writing a new data. This security feature prevents any malicious or unintended writing or erasing of data from occurring.

Conclusion

The AT25DF512C-SSHN-T memory is an efficient and reliable serial Flash memory device with powerful features and additional protection functions. Its vast application field and ultra-secure background operational logic provide fast access time, high-performance, and energy-efficient programming in embedded systems, access control, secure code execution, and system logging. Due to this, the device may be the ideal choice for efficient and reliable memory usage in various systems.
