4 Industrial Communications Device Support

Both the AM243x MCU and AM64x processor series have options that include industrial communication Device protocol software stacks provided by TI, in addition to those available through third parties. The TI-provided protocol stacks are included with the purchase of device feature option F, as shown in Table 3-1, and have been certified on AM243x, AM64x evaluation hardware. Third-party stacks are supported on device feature options D, E, and F.

GUID-20231110-SS0I-R6DB-HCPL-PZ2J37ZR0W7H-low.svgFigure 4-1 AM243x, AM64x Industrial Communication Software Support Options

All Device protocols run on one of the Arm Cortex-RF5 CPU cores (FreeRTOS) and require an ICSSG module (Device protocols do not run on the CPSW Ethernet switch).

Product feature options E and F include an EtherCAT Device license and on-chip EtherCAT Device hardware accelerator. (E and F are the only two options that can run EtherCAT Device software.)

Table 4-1 lists the software stacks included with the purchase of option F. Demonstration versions and example application code of the Device protocols can be found in the AM243x SDK and AM64x SDK. Table 4-2 lists the third parties providing Device protocol support for the AM243x and AM64x.
