Designed for industrial use, the device combines high-performance ARM® Cortex® cores, on-chip memory and robust I/O for deterministic industrial networking, control and secure system designs while supporting industrial temperature operation and surface-mount packaging.

Key Features

• Heterogeneous multi-core processing  ARM® Cortex®-A53, Cortex®-M5F and Cortex®-R5F cores with core speeds up to 1 GHz, 400 MHz and 800 MHz respectively, enabling combined application processing and real-time control.
• Real-time industrial subsystems  Industrial communication subsystems (PRU_ICSSG) support industrial protocols including Profinet IRT/RT, EtherNet/IP, EtherCAT and Time-Sensitive Networking (TSN), with dedicated PRU RISC cores and hardware accelerators for deterministic I/O.
• Memory and storage  DDR subsystem supporting DDR4 and LPDDR4 memory types with a 16-bit data bus and inline ECC; up to 2 MB on-chip RAM with SECDED ECC and a general-purpose memory controller (GPMC).
• High-speed and field interfaces  Multiple Ethernet ports (two 10/100 Mbps and two 10/100/1000 Mbps), USB 3.1 (1 port) and CANbus support to address a wide range of connectivity needs.
• Security and trusted boot  Hardware security features including 3DES, AES, DES, MD5, SHA-1/2, secure boot, cryptography support and Trusted Execution Environment (TEE) capabilities for protected system operation.
• On-chip peripherals for motion and sensing  Multiple Sigma-Delta filters, multi-protocol position encoder interfaces and an Enhanced Capture Module (ECAP) enable precise motion and sensor interfacing in industrial applications.
• Reliability and industrial grade  Industrial operating temperature range from −40 °C to 105 °C, RoHS compliance, SECDED ECC on key memories and error-location modules to support robust system behavior.
• Package and mounting  441-FCBGA package (17.2 × 17.2 mm) with surface-mount mounting for compact, board-level integration.

Typical Applications

• Industrial automation and control  Use for real-time PLCs, motion controllers and distributed I/O where deterministic processing and industrial protocol support are required.
• Industrial networking and gateways  Ideal for protocol gateways and edge networking devices leveraging dual gigabit and dual 10/100 Ethernet ports plus PRU_ICSSG support for fieldbus and TSN.
• Motor and motion systems  Integrates position encoder interfaces, ECAP and Sigma-Delta filters for precise motor control and feedback processing.
• Secure embedded compute  Suitable for secure edge appliances and embedded platforms requiring hardware-enforced secure boot and cryptographic accelerators.

Unique Advantages

• Highly integrated heterogeneous processing: Combines Cortex‑A53 application cores with Cortex‑R5F and Cortex‑M4F real-time subsystems to consolidate application and control tasks on one SoC.
• Deterministic industrial I/O: PRU_ICSSG subsystems and industrial Ethernet support (Profinet, EtherCAT, TSN, etc.) provide the building blocks for low-latency, real-time networking.
• Built-in security foundation: Secure boot, TEE support and a broad set of cryptographic engines (AES, 3DES, SHA, etc.) help protect firmware and data at runtime.
• Scalable memory and interface support: DDR4/LPDDR4 support with inline ECC, on-chip RAM banks and GPMC flexibility simplify memory system design for a range of embedded applications.
• Industrial-grade reliability: ECC-protected memories, error-location modules and an extended operating temperature range support demanding industrial environments.
• Compact surface-mount package: The 441-FCBGA (17.2 × 17.2 mm) package enables dense, board-level integration for space-constrained systems.
