产品概述
描述
Designed for secure ID and banking applications, the ST31R480, and derivatives (ST31R) 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, including MPU and 1-cycle multiplier.
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® 1.5, MIFARE Plus® EV2, and MIFARE® DESFire® EV3.
MIFARE, DESFire, MIFARE Plus, and MIFARE Classic are registered trademarks of NXP B.V. and are used under license.
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 ST31R devices also offer a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1), and an I2C target hardware interface.
Three 16-bit general-purpose timers are available as well as a watchdog timer.
An I²C hardware interface running up to 400 kHz is available. The ISO 7816 pins are used as I²C SCL and SDA.
The ST31R480 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. The NESCRYPT cryptographic processor efficiently supports the public key algorithm with native operations up to 4096 bits long.
The ST31R480 devices operate in the -25 to +85°C temperature range. In contact mode, the devices operate in the supply voltage range of 1.62 V to 5.5 V. They comply with the ISO/IEC 14443 specification limits. A comprehensive range of power-saving modes enables the design of efficient low-power and contactless applications.
The NVM acronym means Non Volatile Memory which is based on flash technology. NVM and flash are equivalent in this datasheet.
