Real-time digital power MCUs

Double real-time performance and enhance security support with the C29 MCU core

The C29 MCU includes the next-generation CPU of the C28 core, which has been around for over two decades. It offers a very long instruction word (VLIW) architecture with a fully protected pipeline, along with multiple instruction sizes.

Benefits:

• Improved instruction parallelism and bus throughput.
• Highly efficient real-time control with low latency.
• High-performance general-purpose and digital signal processing (DSP) capabilities.
• Better code efficiency.
• Safety Integrity Level (SIL) 3 functional safety capabilities with code isolation in hardware.
• Enhanced debugging and trace capability.

Improve system efficiency and safety with accurate fault detection

Edge artificial intelligence (AI) makes electronics more responsive, efficient and secure. Bringing computational power closer to the data source enables decisions on the device instead of in the cloud. Our microcontroller devices are enabled to support edge AI operations, including our edge AI-accelerated devices with our integrated TinyEngine™ NPU.

Benefits:

• Up to 99% accuracy in arc fault detection and grid system condition monitoring.
• Single-chip solution eases design and development.
• Complete tool chain and ecosystem with documentation to support quicker time to market.
• The TinyEngine™ NPU enables five to 10 times lower latency.

Advanced digital power conversion

Our scalable, ultra-low-latency, real-time MCUs enhance efficiency in power electronics. Our portfolio has a range of design resources to help you evaluate and develop your application. 

The on-chip programmable real-time unit (PRU) subsystem on some of our devices enable low-latency processing for tasks like comms and data handling. This allows the main processor to focus on general tasks while offloading computationally expensive or time-critical workloads to the PRU. 

Benefits:

• Highly accurate sensing.
• Higher performance control.
• Advanced actuation.
• Tight peripheral coupling.

Enable run-time functional safety protections

Our MCUs include devices with Technischer Überwachungsverein (TÜV SÜD)-certified functional safety development processes, supporting industrial (up to SIL 3) safety applications. 

Benefits:

• Safety-focused architecture with built-in diagnostic features.
• Certified processes to ease system-level safety assessment.
• Prebuilt software libraries to implement key safety mechanisms.
• Safety and security unit, lockstep core architecture and dual clock comparator.
• Software diagnostic library with implementation examples.

Design secure and reliable systems

Consider our MCUs in applications that require strong security functionality. Our scalable devices are compatible with a comprehensive ecosystem of tools, libraries, software examples and documentation.

Key security modules:

• Hardware security modules
• Safety and security unit
• Dual code security module (DCSM)
• Cryptographic Acceleration
• Secure Boot, Debug & Key mechanisms
• Secure Firmware Update

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.
