AM654x and AM652x Sitara™ processors are Arm® applications processors built to meet the complex processing needs of modern industry 4.0 embedded products.
The AM654x and AM652x devices combine four or two Arm® Cortex®-A53 cores with a dual Arm® 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 Arm® Cortex®-A53 cores in the AM654x are arranged in two dual-core clusters with shared L2 memory to create two processing channels. The two Arm® Cortex®-A53 cores in the AM652x are available in a single dual-core cluster and two single-core cluster options. 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 some AM654x and AM652x devices in addition to granular firewalls managed by the DMSC.
Programmability is provided by the Arm® Cortex®-A53 RISC CPUs with Arm® Neon™ extension, and the dual Arm® Cortex®-R5F MCU subsystem is available for general purpose use as two cores or it can be used in lockstep to help meet the needs of functional safety applications. The PRU_ICSSG subsystems can be used to provide up to six ports of industrial Ethernet such as Profinet IRT, TSN, Ethernet/IP or EtherCAT® (among many others), or they can be used for standard Gigabit Ethernet connectivity.
TI provides a complete set of software and development tools for the Arm® cores including Processor SDK Linux, Linux-RT, RTOS, and Android as well as C compilers and a debugging interface for visibility into source code execution. Applicable functional safety and security documentation will be made available to assist customers in developing their functional safety or security related systems.
