Additional Details

The DS9093A communicates using the 1-Wire protocol, requiring only a single data wire and a ground return for communication. Each iButton has a unique 64-bit registration number that is lasered into the chip during manufacturing, ensuring that it cannot be altered or duplicated. The stainless-steel case protects the internal circuitry from damage and corrosion. The iButton can be easily attached to objects or surfaces using various methods, including adhesive backing, flanges, or locking rings.

The device operates over a wide voltage range (2.8V to 6.0V) and supports data transfer rates up to 16.3 kbits per second. It can withstand extreme temperatures, making it suitable for outdoor and industrial applications. The DS9093A is often used in conjunction with 1-Wire readers and adapters to interface with computer systems and other devices.
