Entry-level Low-Power 32-bit Processor
N705 is an ultra low-power small-size synthesizable general purpose 32-bit softcore embedded processor.
Overview
N705 is an ultra low-power small-size synthesizable general purpose 32-bit softcore embedded processor. With competitive small core size, high power-efficiency and small code size of the V3m ISA, it is the best candidate to replace 8051 and other 8-bit MCUs for small-footprint, cost and power sensitive applications.
For ease of integration in SoC design, it is delivered with a complete softcore development package as well as reference design flow to fit the requirements in all aspects of performance, power consumption, and cost. In addition, N705 is supported by user-friendly development tools, size-optimized MCU libraries and 2-wire low-cost ICE debugger.

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).
