Product details

Overview

AM6422BSDFHAALVR from Texas Instruments is a heterogeneous Arm®-based Sitara™ processor designed for industrial real-time control and application processing. It integrates dual 64-bit Arm Cortex-A53 cores (up to 1.0GHz), two dual-core Arm Cortex-R5F MCUs (up to 800MHz), and one Arm Cortex-M4F MCU (up to 400MHz), all with SECDED ECC on L1/L2/SRAM/TCM. It supports TSN-enabled industrial Ethernet via dual PRU_ICSSG subsystems and is used in programmable logic controllers (PLCs) and motor drives requiring deterministic low-latency execution.

For engineers reviewing the AM6422BSDFHAALVR datasheet, AM6422BSDFHAALVR pinout, AM6422BSDFHAALVR application, or AM6422BSDFHAALVR equivalent, key selection criteria include real-time core count, industrial protocol support (EtherCAT, PROFINET IRT), functional safety compliance (IEC 61508 SIL 2), on-chip memory partitioning (2MB OCSRAM with ECC), and package compatibility (441-pin FCBGA ALV).

Technical Context

The AM6422BSDFHAALVR implements a deterministic SoC architecture with isolated real-time domains: dual R5F subsystems operate at up to 800MHz with 256KB TCM (SECDED ECC), while the M4F core runs at 400MHz with 256KB SRAM (SECDED ECC). Its dual PRU_ICSSG units each provide two RGMII/MII Ethernet ports, six PRU RISC cores, three Data RAMs with ECC, and hardware accelerators for CRC, SUM32, and sigma-delta decimation.

Security is enforced via DMSC-L controller enabling secure boot with hardware RoT, TrustZone-based TEE, cryptographic acceleration (AES-128/192/256, SHA2, PKA), and runtime safety diagnostics including BIST, ESM error signaling, and windowed watchdog timers - all validated for IEC 61508 up to SIL 2 hardware integrity.

FAQ

What is the maximum operating frequency of the Cortex-R5F cores in the AM6422BSDFHAALVR?

The AM6422BSDFHAALVR features two dual-core Arm Cortex-R5F subsystems, each operating at up to 800MHz. This frequency is sustained across both R5F cores within each subsystem under recommended operating conditions and thermal limits specified in the device datasheet. The AM6422BSDFHAALVR uses these R5F cores for time-critical tasks such as industrial Ethernet protocol stacks and motor control loops.

Does the AM6422BSDFHAALVR support full CAN-FD functionality?

The AM6422BSDFHAALVR includes two MCAN modules, but full CAN-FD support depends on the specific feature code embedded in the part number. According to TI's nomenclature documentation, only orderable variants with feature codes E or F enable full CAN-FD operation. The AM6422BSDFHAALVR does not carry those feature codes and therefore supports classical CAN only, not CAN-FD.

What industrial Ethernet protocols are supported by the PRU_ICSSG subsystems in the AM6422BSDFHAALVR?

The AM6422BSDFHAALVR includes two PRU_ICSSG subsystems that support Profinet IRT and RT, EtherNet/IP, EtherCAT (as SubDevice), Time-Sensitive Networking (TSN), and legacy 10/100Mb PRU_ICSS. These protocols are implemented in firmware running on the PRU RISC cores and are validated for deterministic operation with hardware timestamping and low-jitter scheduling.

Is the AM6422BSDFHAALVR qualified for functional safety applications?

Yes, the AM6422BSDFHAALVR is IEC 61508-certified by TÜV SÜD for functional safety applications. It achieves hardware integrity up to SIL 2 and systematic capability up to SIL 3, with built-in safety mechanisms including ECC/parity on critical memories, BIST, ESM error signaling, and dedicated safety-monitoring peripherals accessible via the isolated Cortex-M4F domain.

What package type and pin count does the AM6422BSDFHAALVR use?

The AM6422BSDFHAALVR uses a 441-ball flip-chip ball grid array (FCBGA) package with ALV designation, measuring 17.2mm × 17.2mm and featuring 0.8mm ball pitch. This package is mechanically and thermally compatible with other AM64x variants in the ALV/ANI family, enabling PCB design reuse across the product line.
