Texas Instruments AM6422BSDGHAALV

Overview

AM6422BSDGHAALV from Texas Instruments is a heterogeneous Sitara™ industrial processor featuring dual 64-bit Arm® Cortex®-A53 cores (up to 1.0GHz), two dual-core Arm® Cortex®-R5F real-time subsystems (up to 800MHz), and one Arm® Cortex®-M4F MCU (up to 400MHz), all integrated with dual gigabit PRU_ICSSG for Profinet, EtherCAT, and TSN. It delivers deterministic real-time control for servo drives and PLCs while supporting Linux application processing.

For engineers reviewing the AM6422BSDGHAALV datasheet, AM6422BSDGHAALV pinout, AM6422BSDGHAALV application, or AM6422BSDGHAALV equivalent, key selection factors include its 441-ball FCBGA ALV package, 2MB on-chip SRAM with SECDED ECC, dual PRU_ICSSG with RGMII/MII Ethernet, functional safety compliance up to SIL 2, and support for LPDDR4/DDR4 with inline ECC.

Technical Context

The AM6422BSDGHAALV implements a deterministic SoC architecture with dedicated low-latency paths between R5F cores and peripherals including sigma-delta filters, encoder interfaces, EPWMs, and ECAP modules-enabling sub-microsecond loop timing for motor control. Its memory subsystem partitions 2MB OCSRAM into up to eight 256KB banks, each assignable to individual cores for strict software isolation.

Security is enforced via DMSC-L managing secure boot with hardware root-of-trust, TrustZone-based TEE, cryptographic acceleration (AES-128/192/256, SHA2, PKA), and firewall-protected memory domains. Functional safety features include ECC/parity on critical memories, BIST, ESM error signaling, and dedicated M4F domain with Freedom From Interference (FFI) capability.

FAQ

What is the maximum operating frequency of each processor core in the AM6422BSDGHAALV?

The AM6422BSDGHAALV features dual Arm® Cortex®-A53 cores rated up to 1.0GHz, two dual-core Arm® Cortex®-R5F subsystems operating up to 800MHz, and a single Arm® Cortex®-M4F core running at up to 400MHz. These frequencies are validated under recommended operating conditions and thermal limits specified in the device datasheet. All cores maintain full cache and memory subsystem functionality at their respective maximum speeds.

Does the AM6422BSDGHAALV support CAN-FD, and if so, what configuration is required?

The AM6422BSDGHAALV includes two MCAN modules, but full CAN-FD support requires selection of an orderable part number with feature code D, E, or F-AM6422BSDGHAALV carries feature code D per TI nomenclature documentation, enabling CAN-FD operation up to 5Mbps. No external transceivers are integrated; standard ISO 11898-2/3 compliant transceivers must be used on the MCAN0_TX/MCAN0_RX and MCAN1_TX/MCAN1_RX signal pairs.

How is functional safety implemented in the AM6422BSDGHAALV, and what certifications does it hold?

The AM6422BSDGHAALV implements functional safety through hardware-enforced mechanisms including ECC/parity on critical memories, Built-In Self-Test (BIST) for CPU and on-chip RAM, Error Signaling Module (ESM), runtime voltage/temperature/clock monitoring, and dedicated M4F domain with Freedom From Interference (FFI). It is IEC 61508-certified by TÜV SÜD for systematic capability up to SIL 3 and hardware integrity up to SIL 2.

What industrial Ethernet protocols are accelerated in hardware by the PRU_ICSSG subsystems of the AM6422BSDGHAALV?

The AM6422BSDGHAALV's dual PRU_ICSSG subsystems provide hardware acceleration for Profinet IRT and RT, EtherNet/IP adapter, EtherCAT slave, Time-Sensitive Networking (TSN), and IO-Link Master protocols. Each PRU_ICSSG includes dual RGMII/MII ports, two 64-bit Industrial Ethernet Peripherals (IEPs) for hardware timestamping, and dedicated CRC/sum32 accelerators-enabling deterministic sub-100μs cycle times without A53 CPU intervention.

What memory types and configurations does the AM6422BSDGHAALV support for external storage?

The AM6422BSDGHAALV supports LPDDR4 and DDR4 memory via its DDRSS subsystem with a 16-bit data bus, inline ECC, and speeds up to 1600MT/s. It also integrates a General-Purpose Memory Controller (GPMC) supporting 16-bit operation at 133MHz or 32-bit operation at 100MHz, with Error Location Module (ELM) support for NAND/NOR flash. On-chip, it provides 2MB OCSRAM with SECDED ECC, partitionable into eight 256KB banks.
