8 Detailed Description

8.1 Overview

AM243x is an extension of the Sitara™ industrial-grade family of heterogeneous Arm processors. AM243x

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. AM243x

combines two instances of Sitara’s gigabit TSN-enabled PRU-ICSSG, up to four Cortex-R5F MCUs, and a

Cortex-M4F MCU domain.

AM243x 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 AM243x 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 PRU_ICSSG in AM243x 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. AM243x also supports

secure boot.
