Sales Briefcase
  • Designed for secure ID and banking applications, the ST31P320 and ST31P450 devices 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 55 MHz, the SC000™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.
    Certain devices implement the MIFARE Classic® , MIFARE® DESFire® EV2 or MIFARE Plus® technology.
    An RF interface including an RF universal asynchronous receiver (RFUART) enables contactless communication up to 848 kbps compatible with the ISO/IEC 14443 Type A standard.
    The devices also offer a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1).
    Three 16-bit general-purpose timers are available as well as a watchdog timer.
    The devices feature hardware accelerators for advanced cryptographic functions. The AES accelerator provides a high-performance implementation of the AES-128, AES-192 and AES256 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 devices operate in the –25 to +85 °C temperature range, in the 2.7 V and 5.5 V supply voltage ranges in Contact mode, and comply with ISO/IEC 14443 specification limits. A comprehensive range of power-saving modes enables the design of efficient low-power and contactless applications.
