32bit ARM SC300 secure core with MIFARE™ , SWP for Secure Element and SIM-SWP

The ST33GxxxSM is a serial access microcontroller designed for secure mobile applications that incorporates the most recent generation of ARM® processors for embedded secure systems. Its SecurCore® SC300™ 32-bit RISC core is built on the Cortex® M3 core with additional security features to help to protect against advanced forms of attacks.

The SC300™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set.

The high-speed embedded Flash memory introduces more flexibility to the system.

The ST33GxxxSM also offers a serial communication interface fully compatible with the ISO/IEC 7816-3 standard (T=0, T=1) and a single-wire protocol (SWP) interface for communication with a near field communication (NFC) router in SIM/NFC applications.

The ST33GxxxSM embeds a MIFARE® Library fully compatible with the widely deployed MIFARE® Classic and MIFARE DESFire® EV1 contactless scheme. Both MIFARE® Classic and MIFARE DESFire® EV1 can be used in mobile contactless applications such as Transport & Event ticketing, Access Control, Loyalty programs.

An SPI Master/Slave interface is also available for communication in non-SIM applications.

The ST33GxxxSM features hardware accelerators for advanced cryptographic functions. The EDES peripheral provides a secure DES (Data Encryption Standard) algorithm implementation, while the NESCRYPT crypto-processor efficiently supports the public key algorithm. The AES peripheral ensures secure and fast AES algorithm implementation.

The ST33GxxxSM operates in the –25 to +85 °C temperature range and 1.8 V, 3 V and 5 V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power 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.
