AM6442BSFGHAALV

The AM6442BSFGHAALV is a Sitara™ microprocessor IC combining a dual-core 64-bit ARM® Cortex®-A53 subsystem with a heterogeneous set of ARM® cores and industrial communication processors in a 441-FCBGA (17.2 × 17.2 mm) package. It targets industrial designs requiring mixed application processing, real-time control and industrial networking, integrating high-performance application cores with dedicated real-time and industrial communication subsystems.

Key value comes from multi-core architecture (A53, R5F, M4F and PRU-ICSSG), integrated memory controllers for DDR4/LPDDR4 with ECC, extensive on-chip RAM options, hardware-enforced security features and industrial-grade temperature support for reliable operation in demanding environments.

Key Features

• Core & performance — Dual 64-bit ARM® Cortex®-A53 cluster up to 1.0 GHz with 256 KB L2 shared cache (SECDED ECC). Additional processing includes up to two dual-core ARM® Cortex®-R5F subsystems (up to 800 MHz) and a single ARM® Cortex®-M4F MCU (up to 400 MHz) for real-time tasks.
• Real-time & industrial engines — 2× gigabit Industrial Communication Subsystems (PRU_ICSSG) with support for Profinet IRT/RT, EtherNet/IP, EtherCAT and Time-Sensitive Networking (TSN); each PRU_ICSSG contains dedicated RISC cores, on-chip RAM with ECC and hardware accelerators for deterministic I/O and protocol offload.
• Memory subsystem — On-chip RAM up to 2 MB with SECDED ECC and a DDR subsystem supporting LPDDR4 and DDR4 (16-bit data bus with inline ECC, up to 1600 MT/s). General-purpose memory controller (GPMC) supports parallel external memories.
• High-speed I/O — Integrated Ethernet: 2× 10/100 Mbps and 2× 10/100/1000 Mbps interfaces; USB 3.1 (1) for high-bandwidth peripheral connectivity; additional interfaces including CANbus and PRU-based I/O.
• Security & trusted boot — Hardware-enforced root of trust, secure boot, Arm TrustZone® based TEE and a broad cryptography feature set including AES, RSA, ECC, 3DES, SHA-1/2, MD5, PKA and a hardware random number generator.
• System services & data movement — Integrated device management and data movement subsystems including Block Copy DMA, Packet DMA, secure proxy and ring accelerator for efficient data handling and system control.
• Package & reliability — 441-FCBGA surface-mount package (17.2 × 17.2 mm), industrial-grade operating temperature from −40 °C to 105 °C and RoHS compliance for long-life industrial deployments.

Typical Applications

• Industrial automation and controllers — PRU_ICSSG and R5F subsystems provide deterministic I/O, industrial Ethernet support (Profinet, EtherNet/IP, EtherCAT) and real-time processing for factory automation and PLC designs.
• Motion control and drives — Dedicated real-time cores, encoder interfaces and capture modules support precise motor control, position feedback and low-latency control loops.
• Industrial gateways and edge compute — Dual-core A53 performance combined with secure boot and cryptography enables protocol translation, secure edge processing and connectivity in industrial gateway applications.
• Robotics and machine control — Heterogeneous cores and integrated memory with ECC allow partitioning of high-level planning on A53 cores and real-time actuation on R5F/PRU subsystems.

Unique Advantages

• Heterogeneous multicore integration: Combines application-class A53 cores with real-time R5F and M4F cores plus PRU_ICSSG — enabling consolidation of application, control and protocol tasks on a single device to reduce BOM and PCB complexity.
• Deterministic industrial networking: PRU_ICSSG subsystems provide hardware support for industrial Ethernet protocols and time synchronization (TSN), simplifying design of time-critical networked systems.
• Memory robustness: On-chip RAM with SECDED ECC and DDR support with inline ECC improve system reliability and error protection for critical industrial deployments.
• Comprehensive security: Hardware root-of-trust, secure boot and a wide set of cryptographic accelerators support secure device authentication, firmware protection and runtime isolation.
• Industrial temperature and package: Surface-mount 441-FCBGA in an industrial-grade temperature range (−40 °C to 105 °C) supports deployment in harsh environments.
