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
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.
Cortex®-A53 cores in the AM654x
are arranged in two dual-core clusters with shared L2 memory to create two processing channels. The
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
Programmability is provided by the
Cortex®-A53 RISC CPUs with
extension, and the dual
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
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.
