Designed for industrial-grade systems, the part combines high‑performance processing, multi‑protocol industrial communication support, extensive security features, and robust memory and I/O connectivity to support secure, deterministic embedded designs.

Key Features

• Core & Performance  Specified with a 64‑bit ARM core at 1 GHz (ARM® Cortex®-A53 listed in the product specifications) to support general application processing in embedded systems.
• Co‑processors & Real‑time Subsystems  Integrates co‑processors including ARM® Cortex®-M4F and ARM® Cortex®-R5F plus PRU‑ICSS industrial subsystems and NEON™ SIMD multimedia support for offload and real‑time tasks.
• Memory Support  DDR subsystem supporting DDR4 and LPDDR4 memory types and up to 2 MB of on‑chip RAM (OCSRAM) with SECDED ECC as described in the series datasheet; inline ECC on the DDR data path provides memory reliability.
• Industrial Communication  Multiple Ethernet interfaces with two 10/100 Mbps ports and two 10/100/1000 Mbps ports plus PRU_ICSSG industrial communication engines supporting common industrial protocols and time synchronization features.
• Peripheral & I/O  Integrated USB 3.1 (1), CANbus support and general‑purpose memory controller options provide flexible I/O for networking and field connectivity.
• Security  Comprehensive security features including 3DES, AES, ARM TrustZone (TZ), cryptography engines (PKA, RSA, ECC), secure boot, DRBG, SHA‑1/2, MD5 and a hardware random number generator to support protected designs.
• Package & Temperature  441‑FCBGA package (17.2 × 17.2 mm) in a surface‑mount form factor rated for industrial temperature operation from −40 °C to 105 °C.

Typical Applications

• Industrial Automation & Control  Use as the main application processor in programmable logic controllers, motor drives, and machine controllers where deterministic I/O and industrial networking are required.
• Industrial Ethernet Gateways  Suitable for protocol bridging and edge gateways that require multiple Ethernet ports and PRU‑based offload for protocols such as Profinet, EtherNet/IP, and EtherCAT (supported by the series PRU_ICSSG).
• Secure Embedded Systems  Ideal for embedded devices that require secure boot and hardware cryptography for device authentication, secure storage, and protected execution environments.
• Field Instrumentation & Remote I/O  Supports remote I/O and sensor aggregation with CANbus and high‑speed Ethernet connectivity in harsh industrial environments.

Unique Advantages

• Highly integrated industrial feature set: Combines application and real‑time processing subsystems with industrial communication engines to reduce external component count and simplify system architecture.
• Robust memory reliability: On‑chip RAM with SECDED ECC and DDR inline ECC support improves system uptime and error resilience in long‑running industrial deployments.
• Comprehensive security stack: Hardware root‑of‑trust, secure boot and a broad set of cryptographic primitives enable secure device provisioning and protected operation.
• Multiple high‑speed interfaces: Gigabit and 10/100 Ethernet ports plus USB 3.1 and CANbus provide flexible connectivity options for networking and peripheral integration.
• Industrial temperature rating: Specified operation from −40 °C to 105 °C for deployment in demanding environmental conditions.
