Features
The DS2502S+T&R is a 1Kb Add-Only Memory (AOM) device produced by Maxim Integrated. It features a unique, factory-lasered and unchangeable 64-bit ROM registration number that serves as a node address. The device contains 1024 bits of memory organized as four pages of 256 bits each. Data is written to the DS2502S using a single-wire communication protocol, which simplifies integration by using only one data line and a ground reference. Additionally, the memory is read-only, with data protection features to prevent unauthorized writing once data is set. The device operates over a wide voltage range and is designed for use in various applications that require secure, tamper-proof storage of data, such as electronic tags, product identification, and inventory tracking. It is packaged in a tape and reel format, making it suitable for automated assembly processes.
