Andes Technology Corporation, a leading RISC-V processor core supplier, has announced a collaboration with Rambus to develop a complete low-power, size-optimized secure product for microcontrollers (MCUs) and Internet of Thing (IoT) applications.

According to Statista, the total number of connected IoT devices will grow to 21.5B units by 2025. As the IoT market has exploded, consumers and governments alike are demanding that device and data security requirements are a primary design requirement for all IoT devices. Accordingly, IoT device makers are increasingly demanding that MCUs be secure by design, offering “out of the box” security.

To address these needs, Andes and Rambus are collaborating to offer a secure product for MCUs embedded with the Andes RISC-V -based CPU and Rambus Security Root of Trust. The Rambus Root of Trust securely boots the MCU, protects the device identity and offers authentication, secure debug, and other cryptographic services to the host system. All AndesCore™ RISC-V processors optimally leverage the Rambus Root of Trust to offer these security services and reduce power for compute-intensive cryptographic operations.

“Today, security has been a fundamental and mandatory feature for IoT devices required by markets, consumers, and governments,” said Dr. Charlie Su, Andes Technology CTO and EVP. “To fulfill the requirements of different security levels, we are pleased to collaborate with Rambus to provide an optimized secure solution for microcontrollers. With the integrated platform and FPGA ready Rambus Root of Trust and Andes RISC-V processor IPs, SoC vendors can focus on their core value, key competitiveness and unique differentiation. They don’t need to worry about protecting the system against security threats.”

“As the connected device market continues to expand rapidly, the security of valuable assets and services is a primary concern for users and manufacturers alike,” said Gijs Willemse, senior director of product management, Rambus Security. “This collaboration will provide a strong and low-power security foundation for MCUs. It allows manufacturers to assure their customers that devices will function without the worry of security breaches that risk user privacy or interrupt their cloud services.”

AndesCore™ RISC-V processors, based on AndeStar™ V5 RISC-V architecture, consists a series of high efficiency and low power 32-bit/64-bit CPU core families range from the entry-level N22, mid-range 25-series, advanced 27-series to high-performance superscalar 45-series. The Andes NX27V RISC-V vector processor is designed for broad market segments of today’s computation-intensive applications. Andes Custom Extension™ framework empowers customers to innovate Domain-Specific Acceleration via creating new instructions. AndesCore RISC-V processors have been used in a wide variety of SoCs ranging from microcontrollers to data center servers, and from edge to cloud applications

Providing a hardware-based foundation for security, Rambus offers a catalog of robust Root of Trust solutions, ranging from richly featured military-grade co-processors to highly compact state machines. With a breadth of products applicable from the data center to Internet of Things (IoT) devices, Rambus has a Root of Trust for almost every application.
