Description

General part information

DRA821U Series

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.

Jacinto DRA821x processors also include the concept of the Extended MCU (eMCU) domain. This domain is a subset of the processors and peripherals on the main domain targeted at higher functional safety enablement, such as ASIL-D/SIL-3. The functional block diagram highlights which IP are included in the eMCU. For more details about eMCU and functional safety, see the DRA821 Safety Manual Processors Texas Instruments Jacinto™ 7 Family of Products (SPRUIX4).
