製品概要
概要
Designed for secure ID and banking applications, including biometry, the ST31N600, ST31N500 and ST31N400 devices are serial access microcontrollers that incorporate the most recent generation of Arm® processors for embedded secure systems. The 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 attack.
Cadenced at 60 MHz, the SC000™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.
Some of the devices implement the MIFARE® DESFire® EV3 or MIFARE Plus® EV2 (including MIFARE Classic®) technology.
An RF interface including an RF universal asynchronous receiver (RFUART) enables contactless communication compatible with ISO/IEC 14443 Type A and Type B at up to 848 kbps, and up to 6.8 Mbps with VHBR. It also supports the ISO/IEC 18092 Type F at up to 424 kpbs.
The ST31N platform 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 ST31N platform devices feature hardware accelerators for advanced cryptographic functions. The AES accelerator provides a high-performance implementation of the AES-128, AES-192 and 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 LLP cryptoprocessor efficiently supports the public key algorithm with native operations up to 4096 bits long.
With their dedicated interface, the ST31N platform devices also support biometry or multiple applications by managing the power supply to external components, and offering an SPI master/slave interface or GPIOs in both contact (via the VCC pad) and contactless (RF harvesting) mode.
The ST31N platform 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 complies with ISO/IEC 14443 specification limits. A comprehensive range of power-saving modes enables the design of efficient low-power and contactless applications.
