AT88SC0404CA-SU Datasheet/PDFThe AT88SC0404CA-SU is a family of memory devices specifically designed for secure applications. The devices in this family feature a 13.5K-protect bit array that can detect and correct single-bit errors, and a non-volatile array of one-time programmable security cells that can store up to 256 bits of customer-defined data. The AT88SC0404CA-SU also features a password-locked secure authenticator that uses two-factor authentication for user access.
Applications
The AT88SC0404CA-SU is designed for a wide range of secure applications such as banking, government, healthcare, industrial, and automotive. The AT88SC0404CA-SU can provide data security for digital certificates, license keys, payment cards, identity information, and other sensitive data. The device’s security cells provide a means to store encrypted data, and its error correction circuitry can detect and correct single-bit errors, thus helping to ensure the integrity of the stored data. The AT88SC0404CA-SU can also be used as a portable data token, providing a secure means to store and exchange digital information.
Working Principle
The AT88SC0404CA-SU utilizes a cryptographic protocol that includes a 12-byte password, a 48-byte random number, and an 8-byte authentication code. This protocol is used for authentication, message integrity, and data privacy. The device is designed to meet the highest standards of data security, using 256-bit encryption and message authentication code. The random numbers are generated using a random number generator based on one-time programmable logic.
The AT88SC0404CA-SU also contains both hardware- and software-based security layers that protect the device against unauthorized access and malicious attacks. The hardware security layers are based on a physically unclonable function, which includes a combination of multiple transistors, EPROMs, and laser-programmable fuses that create a unique fingerprint for each device. In addition, the software security layers include an anti-tamper function that prevents malicious code from being inserted into the device.
The AT88SC0404CA-SU also features several anti-theft features. These include an electrical security key to help prevent unauthorized access to the data stored on the device and a low-power detection circuit that triggers an alarm if the device is removed from its secure environment. The device also features a tamper-evident label that alerts users if the device has been tampered with.
The AT88SC0404CA-SU is also designed to meet the industry’s highest standards of data security and privacy. The device is compliant with ISO 7816-3, the universal industry standard for data protection, and FIPS 140-2, the US government’s security standard for data protection.
Conclusion
The AT88SC0404CA-SU is a highly secure memory device that is designed for a variety of secure applications. The device features a 13.5K-protect bit array, 256-bit non-volatile OTP security cells, and two-factor authentication for user access. The AT88SC0404CA-SU also features a variety of security features, including a physically unclonable function, an anti-tamper function, an electrical security key, a low power-detection circuit, and tamper-evident labels.
