Main Application Block Diagram
This diagram illustrates the TEF810X's integration into an automotive system. Power supplies are shown feeding the TEF810X and a central S32R microcontroller, which acts as the Radar processing platform. The TEF810X interfaces with the S32R via SPI, LVDS, and CSI2. The S32R manages radar algorithms, tracking, and utilizes embedded memory (SRAM) and NV memory. The system also incorporates connectivity modules like FlexRay (TJA1083), Ethernet (TJA1100), and CAN-FD (UJA1162) for communication with other automotive networks (Car IVN). Safety and support functions are also depicted.
