Gateway automotive reference design

Description

Automotive trends are rapidly evolving: and as a result: new domain- and zonal-based gateway architectures are being used to efficiently handle the ever-increasing amount of data coming into and moving throughout the vehicle: and getting sent to the cloud. A properly functioning domain (or zonal) gateway safely and securely facilitates data movement between ECUs within a functional domain/zone and the centralized gateway. The centralized gateway safely and securely moves data between numerous domains/zones of the vehicle.This TIDEP-01022 automotive gateway reference design (GCARD) is an easy-to-use: 8-layer PCB detailed design for use as a centralized: domain or zonal controller and is based on our Jacinto™ 7 DRA821 processors. It serves as a starting point for OEMs and Tier 1 suppliers to easily and quickly create a fully functional DRA821 solution in the automotive space.DRA821 processors are high-performance heterogeneous SoCs that integrate legacy automotive connectivity (LIN and CAN) and high-speed interfaces such as PCIe: USB: a 4-port Gigabit Ethernet switch: as well as numerous safety and security features.This design uses a single PMIC (TPS6594x) power architecture with on board OSPI: eMMC: and LPDDR4 memory: as well as debug functionality. The board has hardware connectors that showcase and support a diverse set of communication protocols including five Ethernet ports: 10 CAN-FD ports: four LIN ports: and a PCIE connector. Headers have also been included for easy access to serial protocols such as SPI: UART: GPIOS: and I²C.The high levels of integration in DRA821 processors help lower system costs and make the device useful in a wide variety of gateway use cases.More information on available device capabilities: peripherals: and functional safety and security features is available in the DRA821 data manual.
