The AM62D2 SoC, part of the K3 architecture, is built for high-performance DSP tasks in automotive audio, pro audio, radar, sonar, and medical imaging. It features up to four Cortex-A53 cores (1.4GHz), two Cortex-R5F cores, and a C7x DSP with 2 TOPS MMA. Key interfaces include multi-channel McASP audio, TSN-capable Gigabit Ethernet, and a range of peripherals (UART, SPI, I2C, CAN, USB, eMMC/SD, OSPI, CSI). It supports LPDDR4/DDR4, secure boot with hardware security, and low-power modes with CAN/GPIO/UART wakeup.
AM62D2-EVM evaluation module (EVM) is a low-cost expandable platform board designed for AM62D2 SoC from TI. It supports the following interfaces: * 4 GB LPDDR4 RAM * x2 Gigabit Ethernet expansion connectors * x4 3.5mm TRS Audio Jack Line In * x4 3.5mm TRS Audio Jack Line Out * x2 Audio expansion connectors * x1 Type-A USB 2.0, x1 Type-C dual-role device (DRD) USB 2.0 * x1 UHS-1 capable micro SD card slot * 32 GB eMMC Flash * 512 Mb OSPI NOR flash * x4 UARTs via USB 2.0-B * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs Also resuse Soc specific files from AM62A. A key distinction from AM62A is that the AM62D does not include multimedia components such as the video encoder/decoder, MJPEG encoder, Vision Processing Accelerator (VPAC) for image signal processing, or the display subsystem. Additionally, the AM62D has a different pin configuration compared to the AM62A.
