DS2502R+T&R; 编带
The DS2502R+T&R is a 1Kb add-only memory in 3 pin SOT-23 package. The 1Kb add-only memory identifies and stores relevant information about the product to which it is associated. This information can be accessed with minimal interface for example, a single port pin of a microcontroller. The DS2502 consists of a factory lasered registration number that includes a unique 48bit serial number, an 8bit CRC and an 8bit family code 09h plus 1Kb of EPROM which is user-programmable. The power to program and read the DS2502 is derived entirely from the 1 wire communication line. Data is transferred serially via the 1 wire protocol which requires only a single data lead and a ground return. The entire device can be programmed and then write-protected if desired. Typical applications include storage of calibration constants, maintenance records, asset tracking, product revision status and access codes.
