ここでは、本製品の評価および作業を開始するために理解する必要がある内容のすべてをご紹介しています。
Voltage Range: 2.7V-5.5V. Memory Density: 1-kbit to 256-kbit.
CryptoMemory chips are equipped with a 64-bit embedded hardware encryption engine, four sets of nonreadable, 64-bit authentication keys, and four sets of nonreadable, 64-bit session encryption keys. A cryptographic algorithm encrypts data and passwords, and generates message authentication codes, providing a secure place where information remains safe — even under attack.
CryptoMemory chips can connect to virtually any microcontroller. Atmel offers interface software free of charge for quick implementation. The chips provide standard communication interfaces to microcontrollers and off-the-shelf readers that include a synchronous 2-wire interface (TWI) and an asynchronous interface (ISO 7816-3 in T=0 Mode) for smartcard applications. All CryptoMemory chips are pin-compatible with Atmel’s serial EEPROMs, allowing for security updates without a design overhaul.
