產品總覽

The DS1985-F5+ is an iButton 16Kb add-only in F5 MicroCan package. It 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. The DS1985 consists of a factory lasered registration number that includes a unique 48bit serial number, an 8bit CRC and an 8bit family code (0BH) plus 16Kb of EPROM that is user-programmable. The power to program and read the DS1985 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. Its compact button-shaped profile is self aligning with cup shaped receptacles.
  • 16384bits EPROM communicates with economy of one signal plus ground
  • Architecture allows software to patch data by superseding old page in favour of new programmed page
  • Add only memory where additional data can be programmed into EPROM without disturbing existing data
  • Reduces control, address, data, power and programming signals to a single data pin
  • Multidrop controller for MicroLAN
  • Digital identification and information by momentary contact
  • Chip based data carrier compactly stores information
  • Data can be accessed while affixed to object
  • Economically communicates to bus master with a single digital signal at 16.3Kbps
  • Standard 16mm diameter and 1 wire protocol ensure compatibility with iButton family
