STMicroelectronics Telemaco3P telematics and connectivity processors for connected cars

STMicroelectronics is protecting connected cars against cyber threats with its latest automotive microprocessors that feature a dedicated, built-in security module. The Telemaco3P telematics and connectivity processors (STA1385 and its variants) 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. This places the Telemaco3P devices ahead of the general-purpose application processors typically found in current connected-car systems, according to the company, which lack dedicated hardware-based security.

The chips are also robust, with a 105°C maximum temperature rating for use in locations that can become very hot, such as on top or directly beneath the roof in a smart antenna. They are part of a comprehensive ST strategy to offer products with embedded security functions that include standalone Secure Elements (ST33) and embedded Flash microcontrollers (SPC5).
