Security MCUs target M2M comms

2 April 2008 DSP, Micros & Memory

Infineon has released a new family of security microcontrollers (MCUs) targeting the growing market of machine-to-machine communication for various applications. Machine-to-machine (M2M) applications range from utility monitoring, remote alarm systems, car telematics, fleet management in freight forwarding and rental car companies, to vending machines for stocks level checks.

The new SLM 76 family is available in various package options and has been designed specifically to bring SIM functionality to M2M applications. All members of this family are robust and reliable, and are capable of storing data for at least a decade. They fulfil the tough requirements for high data retention within a broad temperature range even in rough environments such as high humidity, as typical in vehicles and industrial units, and vibrations, which occasionally can be extreme in certain applications.

The security microcontrollers 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 a utility meter.

These MCUs are capable of operating from -40 to +105°C and can achieve between 500 000 and 16 million write-and-erase cycles per page. They are available in conventional chip card modules and also as SMDs in 8-pin VQFN packages.
