Single-core 64-bit Arm® Cortex®-A53, single-core Cortex-R5F, PCIe, USB 3.0 and security

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 the

Sitara device’s gigabit TSN-enabled PRU-ICSSG with up to two Arm® Cortex®-A53 cores,

up to four Cortex-R5F MCUs, and a Cortex-M4F MCU.

AM64x is architected to provide

real-time performance through the high-performance R5Fs, Tightly-Coupled Memory

banks, configurable SRAM partitioning, and dedicated 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 AM64x provides flexible industrial

communications capability including full protocol stacks for EtherCAT SubDevice,

PROFINET device, EtherNet/IP adapter, and IO-Link Master. The PRU-ICSSG further

provides capability for gigabit and TSN based protocols. In addition, the PRU-ICSSG

also enables additional interfaces in the SoC including sigma delta decimation

filters and absolute encoder interfaces.

Functional safety features can be

enabled through the integrated Cortex-M4F along with dedicated peripherals which can

all be isolated from the rest of the SoC. AM64x also supports secure boot.
