The AM263Px Sitara™ Arm® Microcontrollers are built to meet the complex real-time processing needs of next generation industrial and automotive embedded products. The AM263Px MCU family consists of multiple pin-to-pin compatible devices with up to four 400MHz Arm® Cortex®-R5F cores. As an option, the Arm® R5F subsystem can be programmed to run in lockstep or dual-core mode for multiple functional safety configurations. The industrial communications subsystem (PRU-ICSS) enables integrated industrial Ethernet communication protocols such as PROFINET®, Ethernet/IP®, EtherCAT® (among many others), standard Ethernet connectivity, and even custom I/O interfaces. The family is designed for the future of motor control and digital power applications with advanced analog sensing and digital actuation modules.

The multiple R5F cores are arranged in cluster subsystems with 256KB of shared tightly coupled memory (TCM) along with 3MB of shared SRAM, greatly reducing the need for external memory. Extensive ECC is included for on-chip memories, peripherals, and interconnects for enhanced reliability. Granular firewalls managed by the Hardware Security Manager (HSM) enable developers to implement stringent security-minded system design requirements. Cryptographic acceleration and secure boot are also available on AM263Px devices.

TI provides a complete set of microcontroller software and development tools for the AM263Px family of microcontrollers.
