Overview
The AndesCore N9 Family is intended for deeply embedded applications that require optimal interrupt response features, including wireless networking and sensors, micro-controllers, automotive electronics, and industrial control systems. The low-power N9 Family of processors features low gate count, low interrupt latency, and low-cost debug. The processor family provides superior performance and excellent interrupt handling response while meeting the challenges of low dynamic and static power constraints.
The AndesCore N9 Family of CPU cores implement v3, the AndeStar™ patented 32-bit RISC-style CPU architecture. The designer can configure certain parameters to adjust the CPU’s size, power, and performance. For example, the N9 core can be configured with 16 or 32 general registers, two or three read ports on the register file, one or two write ports, a fast or a small multiplier, a 24-bit or 32-bit address space, and different bus (APB, AHB, AHB-Lite, AXI) interfaces to connect to the rest of the system.

When a Platform Provider Becomes a Competitor: Why Arm’s Silicon Strategy Changes the Incentives
I work at a RISC-V IP company, and I genuinely root for Arm — probably more than most people in my position would admit. Not because I’m confused about who competes with whom, but because Arm’s best move for their shareholders is also RISC-V’s biggest tailwind yet.
AndeSentry – Andes’ Security Platform
Security has become a critical requirement across a wide range of applications, including mobile devices, automotive infotainment systems, and embedded platforms such as robotics. These systems must deliver robust security functionality with minimal performance overhead, which in turn requires tight and seamless integration between hardware and software to achieve optimal efficiency.
How Next-Gen Chips Are Unlocking RISC-V’s Customization Advantage
Unlike fixed-ISA alternatives, RISC-V enables developers to create domain-specific processors for their systems-on-chip (SoCs). Custom instructions can boost throughput, reduce energy consumption, and shrink silicon area, all while preserving software compatibility and ecosystem portability. RISC-V’s open nature also reduces vendor lock-in, enabling faster innovation across automotive, AI, security, and high-performance computing (HPC).
