Texas Instruments AM273x/AM273x-Q1 Arm™-Based Microcontrollers

Texas Instruments AM273x/AM273x-Q1 Atm™-Based Microcontrollers are a highly-integrated, high-performance microcontroller 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 through the maximum flexibility of a fully integrated, mixed processor solution.

With an integrated Hardware Security Module (HSM) and functional safety support built-in, large, integrated RAM on a die, and a wide temperature range, the AM273x/AM273x-Q1 offers a safe, secure, and cost-effective solution for many industrial and automotive applications. The Texas Instruments AM273x/AM273x-Q1 device is provided as part of a complete platform solution, including hardware reference designs, software drivers, DSP library, sample software configurations/applications, API guide, and user documentation. The AM273x-Q1 devices are AEC-Q100 qualified for automotive applications.
