AM263P2 Dual-Core Arm® Cortex®-R5F

Texas Instruments 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 400 MHz 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 programmable real-time industrial communications subsystem (PRU-ICSS) enables integrated industrial Ethernet communication protocols such as PROFINET®, Ethernet/IP®, and EtherCAT®, among many others, as well as 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 256 KB of shared tightly coupled memory (TCM) and 3 MB of shared SRAM, significantly reducing the need for external memory. Extensive error correction code (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.
