1 System Description

This 8-layer reference design is based on the DRA829 and TDA4VM automotive applications processor, a highly optimized and scalable device that meets increasing compute and data bandwidth requirements of the automotive industry. The DRA829/TDA4VM Integrates an optimal mix of performance, low power, and data bandwidth to meet evolving market trends. DRA829/TDA4VM is based off a heterogeneous architecture which integrates connectivity, a variety traditional automotive (CAN-FD) and high-speed peripherals (PCIe, USB3.x, Gigabit Ethernet), safety and security (via integrated HSM). Integrated PCIE and Ethernet switches enable increased data movement with low software overhead and lower BOM.

The reference design supports multiple external high-resolution displays. The design also enables 4x camera input for rear-view camera, driver monitoring system(DMS) or surround view(SRV) applications. A dual tuner is used to support AM/FM/HD/DAB and diversity, expanding use to both European and American markets. 4 zone audio output and 4 zone audio input allows for seamless surround sound and speech recognition. With increasing use of connectivity functions and FOTA in the automotive space, the design includes a module that enables enable BT and WiFI. Telematics is also showcased in the design via GPS and GNSS capabilities.

This reference design serves as a starting point for OEMs and Tier1 to easily and quickly create a fully functional DRA829/TDA4VM solution in the automotive space. Leveraging this design can substantially decrease development costs and time to market.
