AM6422BSDFHAALVR

Overview

The AM6422BSDFHAALVR is a microprocessor from the Texas Instruments AM64x Sitara family, featuring a dual-core 64-bit Arm Cortex-A53 subsystem operating at up to 1.0 GHz. It integrates two dual-core Arm Cortex-R5F MCU subsystems running at up to 800 MHz and a single-core Arm Cortex-M4F MCU at up to 400 MHz. The device includes 2 MB of on-chip RAM with ECC, supports LPDDR4/DDR4 memory via a 16-bit bus, and provides two gigabit Industrial Communication Subsystems (PRU_ICSSG). It utilizes a 441-pin FCBGA package.

• Robust security infrastructure with secure boot, hardware root-of-trust, 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 feature code suffix within the part number against the official datasheet nomenclature table to confirm enabled peripherals such as CAN-FD support or functional safety certification levels. Ensure the selected package variant matches the required pinout and thermal specifications for the target PCB layout.

Selection Notes

Select this component when designs require a balance of Linux-capable application processing and hard real-time deterministic control. The inclusion of dedicated industrial Ethernet subsystems makes it suitable for complex automation networks requiring time-sensitive data synchronization without external controllers.

Part Context

This processor belongs to the AM64x Sitara series, an extension of the industrial-grade heterogeneous Arm processor family. It is designed specifically for demanding industrial environments, bridging the gap between general-purpose computing and strict real-time requirements through configurable memory partitioning and isolated execution domains.
