RISC-V CPU IP With ISO 26262 Automotive Functional Safety Compliant
AndesCore™ N25F-SE is a 32-bit CPU IP core that supports ISO 26262 ASIL B level functional safety for automotive applications.
Overview
AndesCore™ N25F-SE is a 32-bit CPU IP core that supports ISO 26262 ASIL B level functional safety for automotive applications. Approved based on the functional safety assignments of a Safety Element Out-of-Context (SEooC), which includes the ISO 26262 compliant development process and the qualitative approach with respect to hardware safety analysis, N25F-SE is certified to be used in safety-related applications.
Based on AndeStar™ V5 architecture that incorporated RISC-V technology, N25F-SE is capable of delivering high per-MHz performance and operating at high frequencies with small gate count. It supports single and double precision floating point instructions, branch prediction for efficient branch execution, Instruction and Data caches, local memories for low-latency accesses, and ECC for memory error protection. Features also includes RISC-V Platform Level Interrupt Controller, AXI 64-bit or AHB 64/32-bit system bus, WFI mode for low power and power management, and JTAG debug interface.

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).
