Product Description
DS2401+ 1-Wire Serial Number Chip
The DS2401+ is a low-cost 1-Wire serial number chip widely used for device identification, PCB tracking, asset authentication, anti-counterfeiting, and system configuration.
Key Functions
- Unique 64-bit ROM ID: Factory-lasered and unchangeable, consisting of 8-bit family code, 48-bit unique serial number, and 8-bit CRC for error detection
- 1-Wire communication protocol: Communicates via a single data line with simple timing sequence
- Parasite power operation: Draws power directly from the 1-Wire data line without an external power supply
- Multidrop capability: Allows multiple devices to share the same 1-Wire bus for simplified system wiring
- Wide operating voltage and temperature range: Compatible with typical embedded system environments
- Built-in CRC generator: Automatically verifies data integrity during transmission
Primary Applications
- Product and PCB identification: Unique ID for board tracking, version management, and lifecycle control
- Asset authentication and anti-counterfeiting: Verify genuine components, modules, or finished products
- System calibration and configuration: Store fixed device identity for automatic parameter loading
- Accessory recognition: Detect and authenticate connected peripherals or modules
- Industrial equipment tracking: Unique identification for maintenance, inventory, and traceability
- Secure device binding: Link hardware ID to software licenses or system permissions
