Microchip Technology, Inc. Specialized ICs AT88SC0404CA-MPTG

The AT88SC0404CA-MPTG is a secure memory device from the Atmel CryptoMemory family, featuring 4-Kbit (512-byte) EEPROM user memory organized into four 1-Kbit zones. Each zone can be configured with distinct access rights, allowing for flexible data management. The device supports self-timed write cycles and offers both single byte and 16-byte page write modes. This IC includes advanced security features such as a 64-bit mutual authentication protocol, cryptographic Message Authentication Codes (MAC), and stream encryption capabilities. It supports multiple key sets and passwords, enhancing its utility for secure applications. The AT88SC0404CA operates on a low voltage supply of 2.7V to 3.6V and communicates via a 2-wire serial interface, compatible with various smart card readers using the ISO 7816-3 protocol. Designed for high reliability, the device boasts an endurance of 100,000 write cycles and a data retention period of up to 10 years. It is available in standard 8-lead plastic packages, ensuring compatibility with existing designs. The AT88SC0404CA-MPTG is suitable for applications requiring secure nonvolatile storage of sensitive information, making it a viable option for engineers seeking a robust memory solution.
