产品概要
描述
Designed for secure ID banking applications, the ST31S600, ST31S500, ST31S400, and derivatives (ST31S platform) are serial access microcontrollers that incorporate the most recent generation of Arm® processors for embedded secure systems. The SecurCore® SC000TM 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 60 MHz, the SC000TM core brings great performance and excellent code density using the Thumb®-2 instruction set.
An RF interface including an RF universal asynchronous receiver/transmitter (RFUART) enables contactless communication compatible with the ISO/IEC 14443 Type A and Type B standards at up to 848 kbps, and up to 6.8 Mbps with VHBR. It also supports ISO/IEC 18092 Type F at up to 424 kbps.
The ST31S 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 ST31S 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 (TDES) 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 its dedicated interface, the ST31S platform also supports companion subsystem applications by managing the power supply to external components and offering an SPI master/slave interface or GPIOs in both contact mode (via the VCC pad) and contactless mode (RF harvesting).
The ST31S 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.
