Telematics processors make vehicles safer

October 02, 2015 // By Julien Happich
STMicroelectronics has introduced a family of application-specific processors for automotive telematics and connectivity applications, the Telemaco2, offering a set of scalable, small-footprint, automotive-grade, Linux-programmable microcontrollers dedicated to in-car systems.

The chips address applications such as automatic calling of emergency services in the event of an accident, continuous car-to-cloud connectivity, remote car diagnostics, and road-topology processing.
The Telemaco2 devices minimize the cost of developing and manufacturing these emerging applications by including only the essential silicon IP blocks, by being independent of modem technology such as 2G/3G/LTE, and by allowing customers to use the wide range of available Linux open-source software components.

Key features of the Telemaco2 processors include an embedded independent boot core, eliminating the need for an external boot MCU; an integrated secure CAN (Controller Area Network) subsystem, eliminating the need for a separate in-vehicle bus controller; pre-integrated and validated GNSS and dead reckoning software library for efficient combination with ST's Teseo multi-constellation automotive-positioning ICs; integrated power management circuitry, and built-in RSA authentication, ensuring security of the embedded system code.
Four devices (STA1074, STA1078, STA1079, and STA1088) offer different combinations of feature sets for cost-effective and scalable telematics implementations. All four devices are available as samples today, with volume production scheduled for December 2015.
