Most comprehensive portfolio for SIM Applications

With the launch of the 3G network technology in the 2000s, the SIM (Subscriber Identity Module) cards became UICCs (Universal Integrated Circuit Cards) and started to play a new role in the mobile ecosystems, focusing more and more on data traffic rather than on pure voice and SMS-based communication. With NFC and Machine-to-Machine, they became in the last years an important enabler for new opportunities in the mobile communications market.

Infineon connects people

Infineon provides a broad variety of products and technology everyone can use to stay connected every time and everywhere – at home, in the office or when out and about. Following the trend of ever-diversifying markets, Infineon has designed a wide range of microcontroller families to support SIM Applications and their specific requirements. This powerful, flexible and broad portfolio comes with an astonishing ease of migration between the various families and outstanding technical support.

Standard SIM

The major task of Standard SIM card in the mobile environment is the authentication in the network, managing the SMS traffic and allowing after sales updates of the mobile carrier. New network technologies such as UMTS (3rd generation) and the upcoming LTE (4th generation) will more and more focus on data rather than on pure voice and SMS based communication.

For Standard SIM products, Infineon offers the SLE 76  and SLC 14 families. Both address all mainstream UICC segments and are widely adopted throughout the market. Their Performance, flexibility and reliability have made them one of the major volume platforms over the last years.

The SLC 14 family  is the 1st family of smart card products in the market being produced in leading edge 65nm embedded flash technology optimized for high volume SIM card applications.

The SLE 76 family  addresses all mainstream UICC segments and is widely adopted throughout the market. Its performance, flexibility and reliability have made it one of the major volume platforms over the last years.


With its vast expertise in SIM and Security applications, Infineon develops secure SIM & UICC controllers, answering adequately to the requirements of the NFC market. NFC is equipped with the Single Wire Protocol interface, which is the standardized interface connection between the NFC UICC/SIM and the CLF (ContactLess Frontend) modem within NFC-enabled mobile devices.

The SLE 97 SOLID FLASH™ family is the state-of-the-art 32-bit product generation from Infineon for high performance security chip cards. It takes it one step further, hosting extensions and improvements in terms of interfaces, performance and flexibility. It comes with a Single Wire Protocol Interface as well as a full Speed USB 2.0 interface.

Top Features:

  •  25% more performance than standard SC300TM products
  •  1.5MB storage for your NFC SIM/UICC
  •  Available in mini-SIM and Micro-SIM
