3 Description

AM243x is an extension of Sitara’s industrial-grade portfolio into high-performance microcontrollers. The

AM243x device is built for industrial applications, such as motor drives and remote I/O modules, which require a

combination of real-time communications and processing. The AM243x family provides scalable performance

with up to four Cortex-R5F MCUs, one Cortex-M4F, and two instances of Sitara’s gigabit TSN-enabled

PRU_ICSSG.

The AM243x SoC architecture was designed to provide best-in-class real-time performance through the high-

performance Arm Cortex-R5F cores, Tightly-Coupled Memory (TCM) 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 AM243x to handle the tight control loops found in servo drives while

the peripherals like FSI, GPMC, ECAPs, PWMs, and encoder interfaces help enable a number of different

architectures found in these systems.

The SoC provides flexible industrial communications capability including full protocol stacks for EtherCAT target,

PROFINET device, EtherNet/IP adapter, and IO-Link Controller. The PRU_ICSSG further provides capability for

gigabit and TSN based protocols. In addition, the PRU_ICSSG enables additional interfaces including a UART

interface, 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. AM243x also supports secure boot.
