Arm Cortex-R MCUs

Our high performance Sitara™ microcontrollers provide highly integrated, safe and secure single-chip solutions for networking applications. A built-in hardware security module protects against attacks, while specialized networking management enables the real-time low-latency modes required for industrial networking applications. Functional safety support simplifies compliance for automotive systems targeting International Organization for Standarization (ISO) 26262 and industrial systems targeting ISO 10218-1.

AM2x microcontrollers (MCUs) are engineered with real-time control features that enable powerful and efficient systems. We have optimized the entire control signal chain from analog-to-digital converter read to pulse-width modulation (PWM) write resulting in control-loop latency that's <1 us. The control subsystem also contains advanced features such as high-resolution (150ps) PWMs and hardware comparators that enable complex control schemes and support high switching frequencies. These devices can also integrate multiple control systems into one MCU.

AM2x microcontrollers are engineered with advanced signal processing capability, including integrated C66x digital signal processors and hardware accelerators for low-power fast Fourier transform computations.  These devices also contain rich communications peripheral options as well as a hardware security module to enable real-time sensing, radar and audio processing. Redundancy and safety features enable operation in challenging and harsh environments. 

Our Functional Safety-Compliant products include both diagnostic mechanisms and safety documentation to help system integrators streamline their ISO 26262 and IEC 61508 system certification. AM2x and Hercules™ microcontrollers include options starting from Automotive Safety Integrity Level (ASIL) B and Safety Integrity Level (SIL) 2 up to ASIL D and SIL 3 to help you meet the specific needs of your automotive and industrial applications. 

Arm Cortex-R MCUs address the emerging security threats of an increasingly connected and complex world. With the security toolbox, developers can rapidly implement their security measures to protect their secure assets including:

• Foundational Security: The basic controls that keep MCU information systems secure including secure boot, cryptographic acceleration, debug security and device ID & keys.
• Run-time Security: Active protection for your containers while they're running, such as trusted execution environment (TEE), secure storage, network security and external memory protection.
• Software and key provisioning security: Functions like secure firmware and software update, software IP protection and initial secure programming.
