3 Description

The AM273x family of microcontrollers are highly-integrated, high-performance microcontrollers based on the

Arm Cortex-R5F and a C66x floating-point DSP cores. The device enables original equipment manufacturers

(OEM) and original design manufacturers (ODM) to quickly bring to market devices with robust software support,

rich user interfaces, and high performance. The device offers the maximum flexibility of a fully integrated, mixed

processor design.

With an integrated Hardware Security Module (HSM), functional safety support built in, large, integrated RAM

on die, and a wide temperature range, the AM273x offers a safe, secure and cost effective design for many

industrial and automotive applications.

The AM273x device is provided as part of a complete platform including hardware reference designs, software

drivers, DSP library, sample software configurations/applications, API guide, and user documentation.
