Overview

The J7200XSOMG01EVM system-on-module—when paired with the J721EXCP01EVM common processor board—lets you evaluate the DRA821 processor for networking applications throughout automotive and industrial markets. These processors perform particularly well in industrial and automotive gateway and edge compute applications, where software-as-a-service models are deployed.

The integrated diagnostics and functional safety features are targeted to ASIL-D/SIL-3 certification requirements. The integrated microcontroller (MCU) island eliminates the need for an external system MCU. The device features Gigabit Ethernet ports with an integrated TSN switch to meet networking use cases that require heavy data bandwidth and also includes PCIe hub functionality. CAN-FD and up to UART interfaces are available on the device. General purpose Arm® Cortex®-R5F subsystems can handle low level, timing critical processing tasks and leave the Arm® Cortex®-A72’s unencumbered for advanced applications.

The EVM is supported by our processor SDK, which includes foundational drivers, compute kernels, and example application frameworks and demonstrations that show you how to take advantage of the powerful, heterogeneous architecture of Jacinto 7 processors.
