3 Description

The low-cost AM62x Sitara™ MPU family of application processors are built for Linux® application development.

With scalable Arm® Cortex®-A53 performance and embedded features, such as: dual-display support and 3D

graphics acceleration, along with an extensive set of peripherals that make the AM62x device well-suited for

a broad range of industrial and automotive applications while offering intelligent features and optimized power

architecture as well.

Some of these applications include:

• Industrial HMI

• EV charging stations

• Touchless building access

• Driver monitoring systems

AM62x Sitara™ processors are industrial-grade in the 13 x 13 mm package (ALW) and can meet the AECQ100

automotive standard in the 17.2 x 17.2 mm package (AMC). Industrial and Automotive functional safety

requirements can be addressed using the integrated Cortex-M4F cores and dedicated peripherals, which can all

be isolated from the rest of the AM62x processor.

The 3-port Gigabit Ethernet switch has one internal port and two external ports with Time-Sensitive Networking

(TSN) support. An additional PRU module on the device enables real-time I/O capability for customer’s own

use cases. In addition, the extensive set of peripherals included in AM62x enables system-level connectivity,

such as: USB, MMC/SD, Camera interface, OSPI, CAN-FD and GPMC for parallel host interface to an external

ASIC/FPGA. The AM62x device also supports secure boot for IP protection with the built-in Hardware Security

Module (HSM) and employs advanced power management support for portable and power-sensitive applications
