3 Description

AM62Ax is an extension of the Sitara? automotive-grade family of heterogeneous Arm? processors with

embedded Deep Learning (DL), Video and Vision Processing acceleration, display interface and extensive

automotive peripheral and networking options. AM62Ax is built for a set of cost-sensitive automotive applications

including driver and in-cabin monitoring systems, next generation of eMirror system, as well as a broad set

of industrial applications in Factory Automation, Building Automation, Robotics, and other markets. The cost

optimized AM62Ax provides high-performance compute for both traditional and deep learning algorithms at

industry leading power/performance ratios with a high level of system integration to enable scalability and lower

costs for advanced automotive platforms supporting multiple sensor modalities in stand-alone Electronic Control

Units (ECUs).

AM62Ax contains up to four Arm? Cortex?-A53 cores with 64-bit architecture, a Vision Processing Accelerator

(VPAC) with Image Signal Processor (ISP) and multiple vision assist accelerators, Deep Learning (DL) and video

accelerators, a Cortex?-R5F MCU Channel core and a Cortex?-R5F Device Management core. The Cortex-

A53s provide the powerful computing elements necessary for Linux applications as well as the implementation of

traditional vision computing based-algorithms such as driver monitoring. Building on the existing world-class ISP,

TI’s 7th generation ISP includes flexibility to process a broader sensor suite including RGB-InfraRed (RGB-IR),

support for higher bit depth, and features targeting analytics applications. Key cores include the next generation

C7000? DSP from Texas Instruments (“C7x”) with scalar and vector cores, dedicated “MMA” deep learning

accelerator enabling performance up to 2 TOPS within the lowest power envelope in the industry when operating

at the typical automotive worst case junction temperature of 125°C.

The 3-port Gigabit Ethernet switch has one internal port and two external ports with TSN support and can be

used to enable industrial networking options. In addition, an extensive peripherals set is included in AM62Ax

to enable system level connectivity such as USB, MMC/SD, Camera interface, OSPI, CAN-FD and GPMC for

parallel host interface to an external ASIC/FPGA. AM62Ax supports secure boot for IP protection with the built-in

HSM (Hardware Security Module) and also employs advanced power management support for portable and

power-sensitive applications.
