AT88SC018-SU-CM Application Field and Working Principle

The AT88SC018-SU-CM is a specialized IC designed by Atmel Corporation. It is part of the AT88SC series of integrated circuits, which is a widely used family of specialized ICs implemented for secure storage and authentication of data.

The AT88SC018-SU-CM is a specialized IC designed for applications such as system-on-chip design, contactless smart card, payTV, discretization, and home network. This IC implements a secure data storage function in order to protect user data, settings, and authentication process. It also supports a variety of cryptographic algorithms and a large range of memory sizes ranging from 256 Bytes to 8192 Bytes.

This IC is primarily used in system-on-chips to securely store cryptographic keys and data, as well as facilitate secure authentication process. The IC supports a variety of different cryptographic algorithms, including those specific to ISO 7816-3, Rijndael (AES), and Triple DES. Another important feature of this IC is its protection against external attacks, such as tamper attempts or signal probing.

The AT88SC018-SU-CM is also capable of providing secure data storage for contactless payment cards, discretization systems, home networks, and payTV applications. This IC supports a variety of host interface protocols, including I2C, USB, SPI, and UART. The IC is also designed to withstand extreme temperatures ranging from -30°C to +85°C.

The working principle of the AT88SC018-SU-CM is based on the serial wire protocol, where the host processor sends commands to the AT88SC018-SU-CM through a simple two-wire output. This IC then responds by acknowledging receipt of the command, executing the command, and returning data to the host processor.

The AT88SC018-SU-CM implements a secure authentication process, where the host processor sends an authentication request to the IC. Then, the IC sends an encrypted message that must be decrypted by the host. This ensures the authenticity of the data and provides protection against malicious attacks.

The AT88SC018-SU-CM also features a built-in tamper detect circuit to detect any attempts at physical tampering, as well as a secure erase and write feature. This IC also features on-chip ECC (error correction code) for enhanced data protection.

The AT88SC018-SU-CM is a specialized IC designed for secure data storage and authentication process. It is a versatile IC and is widely used in various applications, such as system-on-chip design, contactless payment cards, discretization systems, payTV, and home networks.
