3 Description

The AM261x Sitara Arm® Microcontrollers are part of Sitara AM26x real-time MCU families designed to meet the complex real-time processing needs of next generation industrial and automotive embedded products. With scalable Arm Cortex® R5F performance and an extensive set of peripherals, AM261x device is designed for a broad range of applications while offering safety features and optimized peripherals for real time control.

Key features and benefits:

  • Peripherals supporting system level connectivity such as Gigabit Ethernet, USB, OSPI/QSPI, CAN, UARTs, SPI and GPIOs.
  • Granular firewalls managed by Hardware Security Manager (HSM) enable developers to implement stringent security minded system design requirements.
  • Up to two R5F cores in cluster with 256KB of shared Tightly Coupled Memory (TCM) per core along with 1.5MB of shared SRAM, greatly reducing the need for external memory.
