Dedicated telematics processors enhance safety & fuel efficiency

7th October 2015

STMicroelectronics has introduced a family of application-specific processors for automotive telematics and connectivity applications. Called Telemaco2, the family offers a set of scalable, small-footprint, automotive-grade, Linux-programmable MCUs that are dedicated to in-car systems that enhance safety, comfort, and fuel efficiency.

Telemaco2-powered solutions 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.

Telematics is widely expected to become an increasingly important part of all vehicles, including private cars, business fleets, and public transport. This trend is strongly supported by important Government policies such as the recent EU law mandating that all new cars sold in the EU from April 2018 must incorporate "eCall" technology. eCall allows the car to automatically call emergency services after an accident and provide essential information such as the exact location of the vehicle and the direction of travel.

Until now, the automotive telematics industry has used processors that were not specifically designed for this purpose and therefore included more functions—and used more silicon real estate--than is actually needed. The Telemaco2 devices minimise 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.

ST’s Telemaco2 family currently comprises four devices (STA1074, STA1078, STA1079, and STA1088) that 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.
