SLM 76

Infineon Technologies AG has announced a new family of security MCUs targeting the growing market of machine-to-machine (M2M) communication for various applications. M2M applications range from utility monitoring; remote alarm systems; car telematics (for communication between carmakers and owners to signify that an oil change or software updates are required); fleet management in freight forwarding and rental car companies; to vending machines (stocks level checks).

The SLM 76 family of security MCUs is available in various package options and has been designed specifically to bring SIM functionality to M2M applications. All devices in this family are very robust and reliable, and are capable of storing data for at least a decade. They meet the requirements for high data retention within a broad temperature range even in rough environments, as typical in vehicles and industrial units.

The new security MCUs are responsible for the connection and authentication to the mobile network. This allows the secure exchange of information between the background infrastructure, such as the utility company, and the local equipment, such as an utility meter.

The SLM 76 MCUs are capable of operating in broad temperature range, from -40C to 105C. The chips can retain data for at least 10 years and can achieve between 500,000 and 16 million write-and-erase cycles per page, even in harsh environments.

Infineon offers SLM 76 chips in conventional chip card modules and also as SMDs in 8-pin VQFN packages. This packaging eases attaching to equipment and machinery applications and reduces the overall solution cost. In some applications, such as telematics, these standard packages help to cope with harsh environment, like vibrations.

Smart card manufacturers have started developing products and solutions based on the SLM 76 or are conducting initial field tests. Currently, these development efforts center primarily on automotive telematics and metering.

The SLM 76 family currently comprises five products with EEPROM sizes ranging from 256Kbytes to 504Kbytes. They are available in various package types, including sawn wafer, chip card module and 8-pin VQFN package.

The first MCU, the SLM 76CF5120P, is already in volume production. The security MCU features 504Kbyte EEPROM and 12Kbyte RAM. In lots of 200 units, the unit price is around $2.90.
