The DS2401AP-02B-001T&R is a silicon serial number, or 1-Wire® silicon registration number, manufactured by Dallas Semiconductor (now Maxim Integrated). It is a unique, unalterable identification code programmed into the chip by the manufacturer. This device uses the 1-Wire communication protocol, requiring only a single data line plus ground for communication, simplifying integration into various systems.

Applications:

• Asset Tracking: Identifying and tracking physical assets in logistics, inventory management, and supply chain applications.
• Access Control: Authenticating access to secure areas, equipment, or software.
• Medical Devices: Tracking and authenticating medical devices and consumables.
• Authentication: Preventing counterfeiting by verifying the authenticity of products.
• Sensor Calibration: Storing calibration data for sensors and other instruments.

Features:

• Unique 64-bit Registration Number: Each device has a unique, factory-programmed ID.
• 1-Wire Interface: Communicates using a single data line plus ground.
• Low-Cost: Economical solution for identification and tracking.
• Simple Integration: Easy to interface with microcontrollers and other digital systems.
• Wide Operating Voltage: Operates over a wide voltage range.
• Robust: Designed for harsh environments.

Benefits:

• Unique Identification: Provides a reliable method for identifying individual items.
• Simplified Wiring: 1-Wire interface reduces wiring complexity.
• Cost-Effective: Provides a low-cost solution for identification and tracking.

Additional Details:

The DS2401AP-02B-001T&R operates as a slave device on the 1-Wire bus, responding to commands from a master device such as a microcontroller. The 64-bit registration number includes an 8-bit family code, a 48-bit serial number, and an 8-bit CRC (Cyclic Redundancy Check) for data integrity. The device is typically packaged in a TO-92 package, making it easy to mount on PCBs. The 1-Wire protocol allows multiple DS2401 devices to be connected to the same bus, with each device being uniquely addressable. It is available in tape and reel packaging (T&R) for automated assembly.
