Microchip Introduces PIC64HX Microprocessors for Intelligent Edge Applications
The global edge computing market is expected to grow by more than 30% over the next five years, driven by demand from industries such as aerospace, defense, medical, and industrial sectors. In response to this need for high-performance solutions in mixed-criticality systems, Microchip Technology has unveiled the PIC64HX family of microprocessors (MPUs). Unlike conventional MPUs, the PIC64HX series is specifically designed to address the challenges of intelligent edge computing applications.
High-Performance RISC-V MPUs for Advanced AI/ML Applications
The PIC64HX is the latest addition to Microchip’s 64-bit microprocessor portfolio. These multicore RISC-V MPUs offer advanced capabilities for Artificial Intelligence (AI) and Machine Learning (ML) workloads, along with Time-Sensitive Networking (TSN) Ethernet capabilities for seamless real-time data communication. The processors are also equipped with post-quantum cryptography, providing defense-grade security designed to meet future threats posed by quantum computing.
These MPUs are engineered to ensure fault tolerance, scalability, resiliency, and power efficiency, making them ideal for mission-critical applications in aerospace, automotive, and industrial automation.
Integrating Networking and Compute for System Efficiency
According to Maher Fahmi, corporate vice president at Microchip, the PIC64HX MPU brings together advanced networking and compute capabilities, simplifying system designs and lowering development costs. “By embedding TSN Ethernet switching directly into the MPU, we enable developers to align standards-based networking with compute operations, reducing time-to-market and increasing design efficiency,” said Fahmi.
The integrated TSN Ethernet switch supports key emerging standards:
- IEEE P802.1DP: TSN for aerospace onboard communications
- IEEE P802.1DG: TSN for in-vehicle automotive networks
- IEEE/IEC 60802: TSN profile for industrial automation
These features provide reliable, low-latency communication across different industry sectors.
Empowering Intelligent Edge with Versatile Compute Options
The PIC64HX features eight SiFive Intelligence X280 cores, designed for vector processing and high-performance AI workloads. These cores offer flexibility by supporting different configurations:
- Symmetric Multiprocessing (SMP)
- Asymmetric Multiprocessing (AMP)
- Dual-core lockstep mode for enhanced fault tolerance
The architecture also includes WorldGuard hardware-based partitioning, enabling secure isolation for different tasks, which is critical in applications where mixed-criticality systems must run side-by-side safely.
Aviation Industry Sees Potential in RISC-V Technology
The OHPERA Consortium, a coalition of aerospace companies working toward next-generation aviation technologies, recognizes the potential of RISC-V processors. According to Christophe Vlacich, OHPERA’s technical leader, modern aircraft require advanced processors for flight control, cabin networking, engine control, and cockpit displays. “We are excited about the capabilities of Microchip’s PIC64HX MPUs, which meet the performance, security, and networking demands of future aviation systems,” Vlacich noted.
Addressing Future Security Threats with Post-Quantum Cryptography
The rise of quantum computing presents new challenges to existing cybersecurity systems, as many current encryption methods will become vulnerable. In preparation for this shift, the PIC64HX MPUs integrate NIST-approved post-quantum cryptographic algorithms, including:
- FIPS 203 (ML-KEM): Key encapsulation mechanism
- FIPS 204 (ML-DSA): Digital signature algorithm
These algorithms offer enhanced protection for sensitive systems, aligning with evolving security requirements across industries.
Comprehensive Development Tools and Ecosystem Support
Microchip provides a robust suite of development tools to support the PIC64HX MPU family. This includes libraries, drivers, and boot firmware, with support for both open-source and commercial operating systems like Linux and RTEMS, as well as hypervisors such as Xen.
The MPUs leverage Microchip’s Mi-V ecosystem, which offers a wide range of tools and resources to accelerate RISC-V development efforts. To further simplify design, Microchip offers the Curiosity Ultra+ evaluation kit and has partnered with Aries Embedded to create System-on-Modules (SoMs) for mission-critical edge applications.
Andreas Widder, CEO of Aries Embedded, emphasized the value of this collaboration: “As a committed supporter of the RISC-V ecosystem, we are excited to partner with Microchip to bring the PIC64HX to market and support innovative edge solutions.”
Availability and Early Access
Microchip plans to provide PIC64HX MPU samples to its early access partners starting in 2025. For more details or to connect with a Microchip sales representative, please visit Microchip’s official website.
Conclusion: Shaping the Future of Edge Computing
With its blend of high-performance computing, real-time networking, and defense-grade security, the PIC64HX MPU positions Microchip as a leader in the growing edge computing market. The processor’s ability to meet the demands of AI-driven intelligent systems while ensuring security and fault tolerance makes it a valuable solution for industries such as aerospace, automotive, and industrial automation. As edge computing becomes increasingly essential, the PIC64HX MPU family offers a future-ready platform to power the next wave of mission-critical applications.
