The device offers an additional page, named the Identification Page(64 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode. The device’s cascadable feature allows more devices to share a mon 2wire bus. This device is optimized for use in many industrial and mercial applications where low-power and low voltage operation are essential. The device is available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-lead PDIP(1), 5-lead SOT23, and 8-ball UDFN packages. The entire family of packages operates from 1.7V to 5.5V.
