3 Description

Jacinto™ DRA821x processors, based on the Armv8 64-bit architecture, are optimized for gateway systems with

cloud connectivity. The System-on-Chip (SoC) design reduces system-level costs and complexity through

integration—notably, a system MCU, functional safety and security features, and an Ethernet switch for high-

speed communication. Integrated diagnostics and functional safety features are targeted to ASIL-D and SIL 3

certification requirements. Real-time control and low-latency communication are enabled by a PCIe controller

and a TSN capable Gigabit Ethernet switch.

Up to four general-purpose Arm® Cortex®-R5F subsystems can handle low-level, timing-critical processing tasks

and leave the Arm® Cortex®-A72 core unencumbered for advanced and cloud-based applications.
