AM6442BSEFHAALV

Overview

The AM6442BSEFHAALV is a microprocessor within the Texas Instruments AM64x Sitara family, built on 16nm FinFET technology. It features a dual-core Arm Cortex-A53 subsystem operating up to 1.0GHz with 256KB L2 cache and ECC. The device integrates two dual-core Arm Cortex-R5F MCU subsystems at up to 800MHz and a single-core Cortex-M4F for functional safety. Key peripherals include two PRU-ICSSG industrial communication subsystems supporting TSN and EtherCAT, a CPSW3G Ethernet switch, USB 3.1 DRD, PCIe Gen2, and up to 198 GPIOs. It includes 2MB on-chip RAM with ECC and supports DDR4/LPDDR4 memory.

Feature Summary

• Heterogeneous multi-core architecture combining high-performance A53 cores for Linux applications with deterministic R5F cores for real-time control loops.
• Integrated gigabit Industrial Communication Subsystems (PRU-ICSSG) enabling support for Time-Sensitive Networking (TSN), EtherCAT, PROFINET, and EtherNet/IP protocols.
• Comprehensive functional safety capabilities including an isolated Cortex-M4F core, dedicated safety peripherals, and hardware integrity features compliant with IEC 61508 standards.
• Robust security infrastructure featuring hardware-enforced Root-of-Trust, secure boot, Trusted Execution Environment (TEE), and cryptographic acceleration engines.

Applications

• Programmable Logic Controllers (PLC)
• Motor drives
• Remote I/O systems
• Industrial robots
• Condition-monitoring gateways

Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm feature codes, such as functional safety certification or CAN-FD support. Ensure the package type matches the design requirements, as the ALV suffix denotes a 441-pin FCBGA. Confirm that the selected speed grade aligns with the target application's performance needs and thermal constraints.

Selection Notes

Select this processor when designing systems requiring simultaneous execution of complex Linux-based applications and hard real-time industrial control tasks. It is suitable for designs needing robust isolation between safety-critical functions and general-purpose processing. Consider the available pin multiplexing options via SysConfig to optimize peripheral availability for specific interface requirements.

Part Context

This component belongs to the AM64x Sitara processor family, which extends the industrial-grade portfolio with enhanced connectivity and safety features. It shares architectural similarities with the AM6441 but offers additional cores and peripherals. The family is designed to bridge the gap between application processing and real-time control in industrial automation environments.
