The DS2431+ from Analog Devices is an electronic part with Memory (EEPROM) and a 1-wire interface, for communication between two or more devices. It operates with a wide voltage range from 2.8V to 5.25V. The component is packaged in a TO92 (bulk) package. The DS2431+ provides a low-cost, low-power, and reliable solution for memory-centric communications systems. It has the ability to store data that is critical and should not be lost when power is cycled or applied as a very small form factor device. It is backwards compatible with non-1-wire devices. The DS2431+ is designed to operate from -40°C to +85°C, and is ideal for a broad range of applications, including industrial automation systems, consumer electronics, lighting systems, and any other 1-wire connected system.
