AM6422BSDFHAALVR

The AM6422BSDFHAALVR is a Sitara™ microprocessor featuring a dual 64-bit Arm® Cortex®-A53 cluster running at up to 1.0 GHz. This industrial-grade device integrates multiple processing subsystems and industrial communications peripherals to address demanding embedded and industrial control applications.

Built for use cases requiring mixed real-time and application processing, the AM6422 combines high-level application cores with integrated Cortex‑R5F and Cortex‑M4F subsystems, industrial Ethernet engines (PRU_ICSSG), comprehensive security, and flexible memory interfaces to simplify system design and enable deterministic networked control.

Key Features

• CPU Subsystem  Dual Arm® Cortex®‑A53 64‑bit cluster at up to 1.0 GHz with 256 KB L2 shared cache; each core includes 32 KB L1 ICache and 32 KB L1 DCache with ECC/parity protections.
• Real-time and MCU Subsystems  Integrated Arm® Cortex®‑R5F (up to two dual‑core subsystems at up to 800 MHz) for real‑time processing and a single Arm® Cortex®‑M4F MCU up to 400 MHz for control tasks, each with dedicated caches and TCM/SRAM with ECC.
• Industrial Communication Engines (PRU_ICSSG)  Two gigabit Industrial Communication Subsystems (PRU_ICSSG) supporting Profinet IRT/RT, EtherNet/IP, EtherCAT, TSN and backward compatibility with 10/100 Mb PRU_ICSS; each PRU_ICSSG includes dual Ethernet ports and multiple PRU RISC cores for offloaded deterministic processing.
• Memory Subsystem  DDR subsystem supports LPDDR4 and DDR4 with a 16‑bit data bus and inline ECC, plus up to 2 MB on‑chip RAM (OCSRAM) with SECDED ECC configurable in banks for partitioning.
• Peripherals and Interfaces  Integrated interfaces include 2× 10/100 Mbps Ethernet, 2× 10/100/1000 Mbps Ethernet, USB 3.1 (1), CANbus, and a General‑Purpose Memory Controller (GPMC).
• Security and Boot  Hardware‑enforced root‑of‑trust and secure boot, Arm TrustZone® based TEE, cryptographic accelerators and primitives including AES, 3DES, RSA, ECC, SHA‑1/2, PKA, DRBG and a hardware random number generator.
• System Services and DMA  Integrated Device Management Security Controller (DMSC‑L) for system control and services; Data Movement Subsystem with Block Copy DMA, Packet DMA, Secure Proxy and Ring Accelerator.
• Package and Environmental  441‑FCBGA package (17.2 × 17.2 mm), surface‑mount; industrial operating temperature −40 °C to 105 °C. RoHS compliant.

Typical Applications

• Industrial Ethernet Controllers  Use the on‑chip PRU_ICSSG engines and dual gigabit Ethernet ports to implement Profinet, EtherCAT, EtherNet/IP and TSN compliant controllers and switches.
• Industrial Gateways and Edge Compute  Combine Cortex‑A53 application processing with secure boot and cryptography to build secure protocol translation, data aggregation and edge analytics devices.
• Motion and Motor Control Systems  Leverage deterministic PRU cores, encoder interfaces and capture modules for tight control loops and high‑precision position feedback in automation and robotics.
• Real‑Time Control and Safety Systems  Dedicated Cortex‑R5F subsystems provide isolated real‑time processing for safety‑critical control tasks alongside application processors.

Unique Advantages

• Highly integrated processing mix: Dual Cortex‑A53 application cores plus Cortex‑R5F real‑time cores, Cortex‑M4F MCU and PRU engines reduce external component count and simplify partitioning of application and control tasks.
• Deterministic industrial networking: PRU_ICSSG subsystems with dedicated Ethernet ports and IEP time stamping support deterministic protocols such as Profinet and EtherCAT without external offload devices.
• Robust memory architecture: Support for LPDDR4/DDR4 with inline ECC and up to 2 MB of on‑chip RAM with SECDED ECC enables reliable data integrity for critical applications.
• Comprehensive on‑chip security: Secure boot, hardware root‑of‑trust, TrustZone‑based TEE and a wide set of cryptographic primitives help implement secure provisioning, firmware integrity and encrypted communications.
• Industrial temperature and packaging: 441‑FCBGA in a 17.2 × 17.2 mm footprint with −40 °C to 105 °C rating supports deployment in industrial environments.
