The AM62A SoC belongs to the K3 Multicore SoC architecture platform that can run edge AI applications with Video/Vision processing. This provides advanced system integration with high security support to enable a broad set of applications in industrial/automotive markets such as, driver monitoring, machine vision, smart camera, eMirror, front camera, robotics, and building automation. Some highlights of AM62A SoC are: * Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster. Dual/Single core variants are provided in the same package to allow HW compatible designs. * One Device manager Cortex-R5F for system power and resource management, and one Cortex-R5F for Functional Safety or general-purpose usage. * One AI accelerator (up to 2 TOPS), using one C7x256V DSP w/Matrix Multiplier accelerator (MMA) for Deep Learning usage. * VPAC3L(Vision Pre-processing Accelerator), providing 12-bit ISP up to 315MPixel/s RGB+IR support, and Noise Filter for improved integrated imaging and vision image processing. * H.264/H.265 Video Encode/Decode. + Motion JPEG encode * Display support, providing 24-bit RBG parallel interface up to 200MHz pixel clock support for 2K display resolution. * Integrated Giga-bit Ethernet switch supporting up to a total of two external ports (TSN capable). * 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for NAND/FPGA connection, OSPI memory controller, 3x McASP for audio, 1x CSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals. * Dedicated Centralized Hardware Security Module with support for secure boot, debug security and crypto acceleration and trusted execution environment * One 32 bit DDR Subsystem that supports LPDDR4, DDR4 memory types. * Multiple low power modes support, ex: Deep sleep, Standby, MCU-only, enabling battery powered system design.
