Global semiconductors specialist ST Microelectronics introduces the latest generation of its successful ST33 secure microcontroller line, delivering advanced performance, enhanced security, lower power consumption and even greater multi-interface flexibility.

Serving customers across the spectrum of electronics applications, ST Microelectronics is the world’s top supplier of secure chips for NFC Universal Integrated Circuit Cards (UICCs) and embedded Secure Element (eSE) applications. 

ST’s new ST33G1M2 offers the unique ability to 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 in NFC smartphones. 

The ST33G1M2 also supports the complete MIFARE portfolio including MIFARE Classic, MIFARE DESFire and MIFARE Plus. Additional enhancements include an improved EDES+ accelerator supporting 3-key triple DES security, and support for hardware-accelerated AES encryption (AES-HW).

John Devlin, Practice Director at ABI Research comments that the market for embedded and SWP SIM secure element ICs demands the highest levels of security as well as support for recognised standards and interfaces. SIM card manufacturers and device OEMs are looking to choose secure elements offering greater memory capacity to support a growing breadth and volume of applications. The ST33G1M2 positions ST Microelectronics to build upon its significant lead and has the potential to serve additional applications such as pay TV and high-end authentication.

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.

Laurent Degauque, Embedded Security Marketing Director, ST Microelectronics explains the ST33G1M2 takes their industry-leading ST33 secure microcontrollers forward into the next generation, delivering greater performance, flexibility and enhanced security for the secure mobile applications of tomorrow. 

With its unique combination of support for NFC UICC and eSE applications and the entire MIFARE portfolio, plus enhanced connectivity and large on-chip Flash memory, this device dramatically extends opportunities for issuers to manage secure access to multiple services using the same card.

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 maximise 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.
