STMicroelectronics' new ST33G1M2 MCUs function 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 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).

Driving forward the ST33 family of 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.

 

Customers using ST’s ST33 family will experience easy migration of existing solutions onto the new ST33G1M2, taking advantage of ST’s seamless roadmap that enables developers to maximize engineering re-use and deliver enhanced eSE or UICC solutions to market quickly and efficiently. In addition, ST’s dual-factory supply capability (both 8” and 12” fab) for the ST33G1M2 ensures consistent lead times and security of supply.

Major features:

  • 32-bit SC300 secure core based on ARM Cortex-M3
  • 1.2MByte embedded Flash
  • Targeted for EMVCo and EAL5+ certifications
  • Comprehensive MIFARE  support
  • Reduced power consumption and silicon footprint
  • Enhanced connectivity with SPI and GPIO
