The DS2505 is a secure memory that is used for security-sensitive applications. This type of memory is a non-volatile memory, meaning that the data stored in it is retained even when power is removed from the device. The DS2505 is a one-time programmable (OTP) memory, which means it can be programmed only once.

The DS2505 application field can be used for various tasks, including the identification of personnel, access control of critical resources, secure storage of sensitive data and personal identification numbers. It is mainly used for non-contact access control applications where the lack of contact between the reader and the card reduces the chances of electronic attacks.

The main feature of the DS2505 is that it is low power and highly secure. It also provides an additional level of security to the applications that use it by implementing a hardware-based encryption mechanism. The hardware-based encryption makes the data stored in the memory inaccessible to unauthorised users.

The DS2505 has a simple and reliable user interface, allowing the user to read and write data in a secure fashion. It also implements a random number generator (RNG) to ensure that the data stored in the memory is cryptographically secure. The DS2505 also has an on-board voltage regulator and temperature sensor to ensure that the memory remains stable even in extreme conditions.

The DS2505 is based on an array of EPROMs (Electrically Programmable Read-Only Memories). This type of memory uses two lines for writing and reading data, with the two lines being connected to the processor. The writing line is used to send an electrical signal to the memory, while the reading line is used to receive the data from the memory.

The working principle of the DS2505 is based on programming and verification cycles. When a data word is written to the memory, it is first verified to ensure that it is correct. If the verification passes, the data is stored in the memory. If it fails, the data is erased and the programming process is started again.

The DS2505 also features a self-destruct mode. When this mode is activated, the data stored in the memory is erased or scrambled. The self-destruct mode is triggered when the device experiences high physical or electromagnetic stress, or when the power supply of the device is disrupted.

The DS2505 is a low-power secure memory that provides a high level of data security to applications that use it. It is based on a reliable and easy-to-use user interface and is designed to withstand extreme conditions and protect data stored in the memory. The hardware-based encryption and self-destruct mode make the memory more secure and reliable than other types of memory.
