Texas Instruments AM263x Arm™-Based Microcontrollers

Texas Instruments AM263x Arm™-Based Microcontrollers are built to meet the complex real-time processing needs of next-generation industrial and automotive embedded products. The AM263x MCU family consists of multiple pin-to-pin compatible devices with up to four 400MHz Arm® Cortex®-R5F cores. The multiple Arm cores can be optionally programmed to run in lockstep for different functional safety configurations. The industrial communications subsystem (ICSS) enables integrated industrial Ethernet communications such as PROFINET IRT, TSN, or EtherCAT® (among many others), standard Ethernet connectivity, or custom I/O interfacing. The family is designed for advanced motor control and digital power control applications with advanced analog modules.

The multiple R5F cores are arranged in clusters with 256KB of shared tightly coupled memory (TCM) along with 2MB of shared SRAM, eliminating the need for external memory. Extensive ECC is included on on-chip memory, peripherals, and interconnect for enhanced reliability. Cryptographic acceleration and secure boot are also available on AM263x devices in addition to granular firewalls managed by the HSM for developers to design the most secure systems. A complete set of microcontroller software and development tools for the Texas Instruments AM263x family of microcontrollers is available.
