It is targeted for automotive gateway, vehicle compute systems, Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications. The SoC aims to meet the complex processing needs of modern embedded products. Some highlights of this SoC are: * Dual Cortex-A72s in a single cluster, two clusters of lockstep capable dual Cortex-R5F MCUs and a Centralized Device Management and Security Controller (DMSC). * Configurable L3 Cache and IO-coherent architecture with high data throughput capable distributed DMA architecture under NAVSS. * Integrated Ethernet switch supporting up to a total of 4 external ports in addition to legacy Ethernet switch of up to 2 ports. * Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems, 20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C and I2C, eCAP/eQEP, eHRPWM among other peripherals. * One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL management.
