AM654x and AM652x Sitara Arm applications processors are built to meet the complex processing needs of modern industrial embedded products.

The AM654x and AM652x devices combine four or two Arm Cortex-A53 cores with a dual Cortex-R5F MCU subsystem which includes features intended to help customers achieve their functional safety goals for their end products and three Gigabit industrial communications subsystems (PRU_ICSSG) to create a SoC capable of high-performance industrial controls with industrial connectivity and processing for functional safety applications. AM65xx is currently undergoing assessment to be certified by TÜV SÜD

according to IEC 61508.

The four A53 cores are arranged in two dual-core clusters with shared L2 memory to create two processing channels. Extensive ECC is included on on-chip memory, peripherals, and interconnect for reliability. The SoC as a whole includes features intended to help customers design systems that can achieve their functional safety goals (assessment pending with TÜV SÜD). Cryptographic acceleration and secure boot are available on AM654x and AM652x devices in addition to granular firewalls manag...
