Texas Instruments AM243x Dual-Core Arm®-Based Cortex® MCUs are built for industrial applications, such as remote I/O modules and motor drives, which require a combination of processing and real-time communications. The AM243x family provides scalable performance with up to four Cortex-R5F MCUs, one Cortex-M4F, and two Arm-Based gigabit TSN-enabled PRU_ICSSG instances.
The Texas Instruments AM243x SoC architecture was designed to provide real-time performance through the high-performance Arm Cortex-R5F cores. These devices include tightly-coupled memory banks, configurable SRAM partitioning, and dedicated low-latency paths to and from peripherals. Combined, these allow for rapid data movement in and out of the SoC. This deterministic architecture allows AM243x to handle the tight control loops in servo drives. At the same time, the peripherals like FSI, ECAPs, GPMC, PWMs, and encoder interfaces help enable several different architectures in these systems.
The SoC provides flexible industrial communications capability, including full protocol stacks for EtherCAT target, IO-Link Controller, PROFINET device, and EtherNet/IP adapter. The PRU_ICSSG further provides the ability for gigabit and TSN-based protocols. In addition, the PRU_ICSSG enables additional interfaces, including a UART interface, absolute encoder interfaces, and sigma-delta decimation filters. Functional safety features can be enabled through the integrated Cortex-M4F and dedicated peripherals, which can all be isolated from the rest of the SoC. AM243x also supports secure boot.
