Product details
Overview
AM6441BSEGHAALVR from Texas Instruments is a heterogeneous Arm®-based Sitara™ processor designed for industrial real-time control and application processing. It integrates one dual-core Arm Cortex-A53 subsystem (up to 1.0GHz), two dual-core Arm Cortex-R5F MCU subsystems (up to 800MHz), and one single-core Arm Cortex-M4F (up to 400MHz), with 2MB on-chip SRAM (SECDED ECC), dual PRU_ICSSG for TSN-enabled industrial Ethernet, and functional safety support up to SIL 2. It targets programmable logic controllers and motor drives requiring deterministic real-time response alongside Linux-capable application processing.
For engineers reviewing the AM6441BSEGHAALVR datasheet, AM6441BSEGHAALVR pinout, AM6441BSEGHAALVR application, or AM6441BSEGHAALVR equivalent, key selection considerations include its ALV 441-ball FCBGA package, dual PRU_ICSSG with RGMII/MII, 2× MCAN with optional CAN-FD, integrated DDR4/LPDDR4 controller, and functional safety certification per IEC 61508.
Technical Context
The AM6441BSEGHAALVR implements a deterministic SoC architecture with dedicated low-latency paths between R5F cores and peripherals including sigma-delta filters, encoder interfaces, EPWM, and ECAP modules - enabling tight servo control loops. Its memory subsystem partitions 2MB OCSRAM into up to eight 256KB banks, each assignable to individual cores for software isolation.
Security is enforced via DMSC-L managing secure boot with hardware RoT, TrustZone-based TEE, cryptographic acceleration (AES-128/192/256, SHA2-224/256/384/512, PKA), and runtime diagnostics including BIST, ESM error signaling, and voltage/temperature monitoring.

FAQ
What is the maximum operating frequency of each processor core in the AM6441BSEGHAALVR?
The AM6441BSEGHAALVR features a dual-core Arm Cortex-A53 subsystem rated up to 1.0GHz, two dual-core Arm Cortex-R5F subsystems operating up to 800MHz, and a single-core Arm Cortex-M4F running up to 400MHz. These frequencies are specified under recommended operating conditions and validated across temperature and voltage ranges per TI's AM64x datasheet revision JUNE 2026.
Does the AM6441BSEGHAALVR support full CAN-FD on both MCAN interfaces?
No - full CAN-FD support on the AM6441BSEGHAALVR depends on its feature code. Per TI's Device Comparison Table (Table 4-1), AM6441 has feature code D, which enables optional CAN-FD. Full CAN-FD is only guaranteed on orderable part numbers with feature codes E or F. Engineers must verify the specific feature code of their AM6441BSEGHAALVR shipment against TI's nomenclature guide.

The PRU_ICSSG subsystem in the AM6441BSEGHAALVR supports Profinet IRT and RT, EtherNet/IP, EtherCAT, Time-Sensitive Networking (TSN), and legacy 10/100Mb PRU_ICSS. Protocol stack implementation requires TI's Processor SDK and is validated for device feature codes D, E, or F - AM6441BSEGHAALVR carries feature code D, confirming industrial protocol support.
Is the AM6441BSEGHAALVR qualified for functional safety applications?
Yes - the AM6441BSEGHAALVR is IEC 61508 certified by TÜV SÜD for functional safety applications, with systematic capability up to SIL 3 and hardware integrity up to SIL 2. It includes dedicated safety mechanisms such as ECC/parity on critical memories, BIST, ESM error signaling, and a configurable isolated safety domain centered on the Cortex-M4F core and associated peripherals.
What package type and ball count does the AM6441BSEGHAALVR use?
The AM6441BSEGHAALVR uses the ALV package: a 441-ball flip-chip ball grid array (FCBGA) with 17.2mm × 17.2mm footprint and 0.8mm pitch. This package is mechanically identical to the ANI variant and shares the same pinout, thermal, and electrical characteristics as defined in TI's Mechanical, Packaging, and Orderable Information documentation.
