The product is STMicroelectronics' ST95F8063R, a 1Kbit EEPROM with self-timed write cycle, single byte or 16-byte page write mode, programmable access rights, 37-byte OTP area and 160-byte area. In addition, the product also has high security features, including a 64-bit mutual authentication protocol, encrypted checksum, stream encryption, four key sets for authentication and encryption, eight sets of two 24-bit passwords, anti-tearing function and voltage and frequency monitor. In addition, the product also has smart card features, embedded application features and high reliability features.
The AT88SC0104C is a high‑performance secure memory from Atmel’s CryptoMemory® family, offering 1 Kbit of EEPROM user memory with advanced security features such as mutual authentication, encrypted checksums, and stream encryption. The device supports ISO 7816‑3 asynchronous T=0 protocol and a 2‑wire serial interface for fast communication.
The handbook includes pin‑out diagrams, electrical characteristics, timing diagrams, and mechanical dimensions. It details the four 32‑byte user zones, configuration memory layout, and provides operating ranges for voltage, temperature, and clock frequencies, making it a comprehensive reference for designers integrating the chip into smart‑card or embedded applications.
