8.1 Overview

AM64x is an extension of the Sitara™ industrial-grade family of heterogeneous Arm processors. AM64x is built for industrial applications, such as motor drives and programmable logic controllers (PLCs), which require a unique combination of real-time processing and communications with applications processing. AM64x combines two instances of Sitara’s gigabit TSN-enabled PRU-ICSSG, up to two Arm Cortex-A53 cores, up to four Cortex-R5F MCUs, and a Cortex-M4F MCU domain.

AM64x is architected to provide real-time performance through the high-performance R5Fs, Tightly-Coupled Memory banks, configurable SRAM partitioning, and low-latency paths to and from peripherals for rapid data movement in and out of the SoC. This deterministic architecture allows for AM64x to handle the tight control loops found in servo drives, while the peripherals like FSI, GPMC, PWMs, sigma delta decimation filters, and absolute encoder interfaces help enable a number of different architectures found in these systems.

The Cortex-A53s provide the powerful computing elements necessary for Linux applications. Linux, and Real-time (RT) Linux, is provided through TI’s Processor SDK Linux which stays updated to the latest Long Term Support (LTS) Linux kernel, bootloader and Yocto file system on an annual basis. AM64x helps bridge the Linux world with the real-time world by enabling isolation between Linux applications and real-time streams through configurable memory partitioning. The Cortex-A53s can be assigned to work strictly out of DDR for Linux, and the internal SRAM can be broken up into various sizes for the Cortex-R5Fs to use together or independently.

The PRU_ICSSG in AM64x provides the flexible industrial communications capability necessary to run gigabit TSN, EtherCAT, PROFINET, EtherNet/IP, and various other protocols. In addition, the PRU_ICSSG also enables additional interfaces in the SoC including sigma delta decimation filter modules and absolute encoder interfaces.

Functional safety features can be enabled through the MCU domain with an integrated Cortex-M4F and dedicated peripheral set which can all be shared or isolated from the rest of the SoC. AM64x also supports secure boot.
