Texas Instruments Cortex-R5F Sitara™ AM243x Microcontrollers

Arm® Cortex®-R5F based AM243x Microcontroller family from Texas Instruments 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 is designed for best-in-class real-time performance and provides high performance Arm® Cortex®-R5F cores, Tightly-Coupled Memory banks, configurable SRAM partitioning, and dedicated low-latency paths to and from peripherals for rapid data movement in and out of the SoC.
