Maxim Integrated DS28CM00R-A00+V Silicon Serial Number

The DS28CM00R-A00+V from Maxim Integrated is a robust, low-power silicon serial number IC that provides a unique identity to hardware systems. Its primary function is to offer a guaranteed unique 64-bit ROM ID, which is factory-lasered into each chip, ensuring that no two devices are identical. This feature is crucial for device authentication, inventory control, and tracking applications across various industries.

The DS28CM00R-A00+V is designed to be easily integrated into your system with its compact SOT-23 package, making it ideal for space-constrained applications. The device operates over a wide voltage range of 2.5V to 5.5V, which allows for flexibility in various power environments and compatibility with both 3.3V and 5V systems.

One of the key advantages of this product is its multi-drop capability, which enables several devices to be connected to a single data line for efficient communication. This feature simplifies the design of systems that require multiple unique IDs. Additionally, the DS28CM00R-A00+V supports the 1-Wire protocol, a proprietary interface by Maxim Integrated, which minimizes the number of GPIOs needed for communication with a microcontroller, as only a single data line (and ground for reference) is required.

The device also includes an internal resistor, which eliminates the need for external components when using the 1-Wire protocol. This integrated pull-up resistor further simplifies the design and reduces the bill of materials for the system designer.

Maxim Integrated ensures the reliability of the DS28CM00R-A00+V by providing a wide operating temperature range from -40°C to +85°C, making it suitable for industrial and commercial applications where extreme conditions may be encountered.

In summary, the DS28CM00R-A00+V is an essential component for any system requiring a unique ID for security, tracking, or inventory purposes. Its ease of integration, low-power operation, and robust communication protocol make it an excellent choice for a wide range of applications.
