NXP shrinks High-Speed CAN system basis chips

December 09, 2013 // By Christoph Hammerschmidt
With a new family of CAN system basis chips (SBCs), NXP responses to the demand of automotive electronics designers to further reduce the size of electronic control units. The devices support the latest enhancements of the CAN in-car networking standard such as high bandwidth and flexible data rate as well as partial networking according to ISO/NP 11898-2/5/6.

Driving new benchmarks in miniaturisation, the UJA116x family of SBCs optimises performance in a broad range of automotive ECU applications, such as steering, cameras and dashboards, where board space is at a premium. The new UJA116x family of SBCs integrates common functionalities such as standby or sleep mode CAN transceiver, a 5V voltage regulator, a 5V protected sensor supply and watchdog in a compact HVSON14 package (3.5 x 5.5 mm), enabling the industry to further reduce the size of the ECU with a robust and cost-effective solution.

In response to industry requirements to drive energy efficiency, the top-of-the-range UJA1168 also supports partial networking – a major innovation in power efficiency defined in the industry standard ISO11898-6. In current in-vehicle networking architectures, ECUs are always active and consuming power when the vehicle is in use. CAN Partial networking changes this model by activating only those ECUs that are functionally required, while the other ECUs remain in a low-power state until needed. This equates to significant savings in power consumption and CO2 emissions.

The UJA1168 also supports CAN FD Passive, which means UJA1168-based ECUs can remain inactive during CAN FD communication and become active when there is regular CAN communication.
