3 Description

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.
