8 Detailed Description

8.1 Overview

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 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 managed by the DMSC.

Programmability is provided by the quad-core Arm Cortex-A53 RISC CPUs with Neon 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, 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 safety documentation will be made available to assist customers in developing their

functional safety related systems.

(SoC), see the device TRM.
