The new Telemaco3P telematics and connectivity processors (STA1385 and its variants) are the first automotive microprocessors to integrate a powerful, dedicated, isolated Hardware Security Module (HSM), which acts like an independent security guard to watch data exchanges and encrypt and authenticate messages.

The HSM securely checks the authenticity of received messages and any external devices that try to connect and protects against eavesdropping.

With this HSM on-chip, Telemaco3P devices are ahead of the general-purpose application processors typically found in current connected-car systems, which lack dedicated hardware-based security. ST's new chips are also extremely robust, with a 105°C maximum temperature rating for use in locations that can become extremely hot, such as on top or directly beneath the roof in a smart antenna.

"Realizing the benefits of connected cars requires strong protection against cyber-attacks," said Antonio Radaelli, Infotainment Business Unit Director, Automotive and Discrete Product Group, STMicroelectronics. "Our new Telemaco3P processors combine ST's proven expertise in hardware security and knowledge of the automotive industry's standards and requirements to lay solid ground for safe and enjoyable connected motoring."

The new automotive processors are part of a comprehensive ST strategy to offer products with embedded security functions that include stand-alone Secure Elements (ST33) and embedded Flash microcontrollers (SPC5).

ST is providing engineering samples of the STA1385 to lead partners now and full production is scheduled for mid-2018.
