製品概要
概要
Designed for secure ID and banking applications, the ST31H platform products (ST31H320, ST31H256, ST31H192 and ST31H128) are serial access microcontrollers that incorporate the most recent generation of ARM processors for embedded secure systems. Their SecurCore® SC000™ 32-bit RISC core is built on the Cortex™ M0 core with additional security features to help to protect against advanced forms of attacks.
Cadenced at 28 MHz, the SC000™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.
The ST31H platform offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1).
Three 16-bit general-purpose timers, as well as a watchdog timer, are available.
The devices feature hardware accelerators for advanced cryptographic functions. The AES accelerator provides a high-performance implementation of AES-128, AES-192, AES-256 algorithms. The 3-key Triple DES accelerator (EDES+) peripheral enables Cipher Block Chaining (CBC) mode, fast DES and triple DES computation based on three key registers and one data register, while the NESCRYPT cryptoprocessor efficiently supports the public key algorithm with native operations up to 4096 bits long.
The ST31H platform operates in the –25 to +85 °C temperature range at 1.8 V, 3 V and 5 V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power applications.
