Key Products
Telematics and Connectivity Control Units, TCU and CCU, are at the heart of the complex telematics system present in the latest vehicles. They need to provide all the intra-system connectivity to a number of modules or sub-systems, such as wideband cellular modems and wireless connectivity modules (including Bluetooth, Wi-Fi...). Interfacing with a variety of in-vehicle data and control busses and ensuring their security are some of the key challenges in designing an automotive telematics unit.
