AM243x Dual-Core Arm®-Based Cortex® MCUs

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.
