Arm Cortex-R MCU

Our high performance Sitara™ MCUs 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.

AM2 MCUs are engineered for real-time control, delivering powerful and efficient systems. Optimized signal chain (analog-to-digital converter read to PWM write) results in <1us control-loop latency. Advanced features include high-resolution PWMs (150ps) and hardware comparators support complex control schemes and high switching frequencies.

The on-chip programmable real-time unit (PRU) subsystem enables efficient, low-latency processing for tasks like digital signal processing and sensor data handling. This allows the main processor to focus on general tasks while offloading computationally expensive or time-critical workloads to the PRU. The programmable nature of the PRU cores accelerates this process.

AM26 MCUs with OptiFlash technology aim to minimize performance gaps compared to MCUs with integrated flash through features like a dedicated external flash controller with flash cache, hardware boot acceleration, inline error coding and encryption. This architecture enables low-latency, secure code execution while offering greater flexibility and scalability.

AM2 microcontrollers are engineered with advanced signal processing capability, including integrated C66 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 MCUs include options starting from ASIL-B/SIL-2 up to ASIL-D/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.
