Description
Dallas Semiconductor DS1982U-F5 Ibutton 1KB F5 Maxim Read/Write Data Carrier 10pcs
From the Manufacturer
The DS1982 1Kb Add-Only iButton is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware, for example, a single port pin of a microcontroller. The DS1982 consists of a factory lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (09h) plus 1Kb of EPROM that is user-programmable. The power to program and read the DS1982 is derived entirely from the 1-Wire communication line. Data is transferred serially via the 1-Wire protocol that requires only a single data lead and a ground return. The entire device can be programmed and then write-protected if desired. Alternatively, the part may be programmed multiple times with new data being appended to, but not overwriting, existing data with each subsequent programming of the device.
Condition: Open Box
