eFuse Controller IP
The Neuchips eFuse Controller IP is a robust hardware solution designed to manage embedded fuse (eFuse) arrays. It provides a secure and automated mechanism for programming, reading, and reloading eFuse bits, ensuring reliability and ease of integration into modern SoC and AI ASIC designs.
Key Features
- AMBA 3.0 APB interface for register access
- Automated eFuse read, program, and reload operations
- Protection against repeated programming of the same bits
- Support for 32-bit aligned read/program operations
- Software-configurable timing for flexible operation
- Direct bypass mode for ATE and debugging
- Noise blocking during scan/DFT mode
- Retains data securely with hardware reload after reset
Benefits
- Simplifies eFuse array management with a standardized interface
- Reduces design risk by preventing misprogramming and data corruption
- Enhances reliability with built-in safeguards and error handling
- Ensures compatibility across a wide frequency range (1 MHz – 1 GHz)
- Flexible integration into customer SoC and AI ASIC platforms
