MCUs add security to mobile and consumer applications
STMicroelectronics extending its offering of secure chips for NFC Universal Integrated Circuit Cards (UICCs)[the smart card used in mobile terminals in GSM and UMTS networks] and embedded Secure Element (eSE) Element applications, has introduced the latest generation of its ST33 secure microcontroller line, delivering advanced performance, enhanced security, lower power consumption and even greater multi-interface flexibility.
ST33G1M2 functions either in a mobile-phone NFC UICC, which handles mobile payments alongside SIM applications and user-data storage, or as a dedicated embedded secure chip in NFC smartphones. The ST33G1M2 is also unique in supporting the complete MIFARE portfolio including MIFARE Classic, MIFARE DESFire and MIFARE Plus. Further enhancements include an improved EDES+ accelerator supporting 3-key triple DES security, and support for hardware-accelerated AES encryption (AES-HW).
As secure microcontrollers suitable for both NFC (Near Field Communication) UICC and eSE applications, ST’s new ST33G1M2 provides enhanced interfaces including Single-Wire Protocol (SWP) and a Serial Peripheral Interface (SPI), making the device suitable for a wide variety of form factors and applications. Major features of ST33G1M2 include:
32-bit SC300 secure core based on ARM Cortex-M3
1.2 MByte embedded Flash
Targeted for EMVCo and EAL5+ certifications
Comprehensive MIFARE support
Reduced power consumption and silicon footprint
Enhanced connectivity with SPI and GPIO
The ST33G1M2 is in full production now, and available in wafers or micromodules, or in DFN8 or WLCSP packages.
