製品概要
概要
Designed for secure ID and banking applications, the ST31G480, ST31G384, ST31G320 and ST31G256 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.
Some devices implement the MIFARE®DESFire®EV1 or MIFARE Plus®(including MIFARE®Classic) technology. MIFARE, 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 ISO/IEC 14443 Types A, B and B’ as well as ISO/IEC 18092 standards.
Very-high bitrates (ASK VHBR) up to 3.4 Mbps in reception and 6.8 Mbps in transmission are possible.
A Simultaneous mode where contactless communication can be enabled while the device is in Contact mode is also available.
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 with interrupt capability 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 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 devices operate in the –25 to +85 °C temperature range, at 2.1 V, 3 V and 5 V supply voltage ranges in Contact mode, and complies with the ISO/IEC 14443 and ISO/IEC18092 specification limits. A comprehensive range of power-saving modes enables the design of efficient low-power and contactless applications.
In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK®packages, depending on their level of environmental compliance. ECOPACK®specifications, grade definitions and product status are available at: www.st.com. ECOPACK®is an ST trademark.
