2.3.1 AM6442 Microprocessor

The AM6442 microprocessor is equipped with a dual 64-bit Arm Cortex-A53 microprocessor subsystem that operates at up to 1.0 GHz. Additionally, the AM6442 features 2 × dual-core Arm Cortex-R5F MCUs that can operate at up to 800 MHz for real-time processing tasks, such as industrial Ethernet software stacks, Ethernet packet switching, or motor control. The AM6442 also supports 2 × gigabit Industrial Communication Subsystems (PRU-ICSSG), which can support up to 4 physical gigabit Ethernet ports. The integrated Ethernet switch (CPSW3G) supports two additional gigabit Ethernet ports.

The AM6442 supports high-speed interfaces such as USB 3.1 Dual-Role Device (DRD), LPDDR4 and DDR4 memory with ECC, security features, media and data storage, and general connectivity.

In this reference design, a system-on-module (SOM) TQMa64xxL from the manufacturer TQ is used, which includes all necessary components such as the AM6442 MPU, power management, LPDDR4 memory, eMMC NAND flash, clock generation, and EEPROM. For more technical information, please refer to the SOM data sheet.
