Product Description
DS1990A Serial Number Magnetic Ibutton Key Fob with Holder

  The DS1990A Serial Number iButton is a rugged data carrier that acts as an electronic registration number for automatic identification. The DS1990A consists of a factory-lasered, 64-bit ROM that includes an unique 48-bit serial number, an 8-bit CRC and an 8-bit Family Code (01h). Data is transferred serially via the 1-Wire protocol which requires only a single data lead and aground return. The DS1990A is fully compatible with the DS1990 Serial Number iButton but provides the addi-tional 1-Wire protocol capability that allows the Search ROM command to be interpreted by the DS1990A and therefore allows multiple DS1990A devices to reside on a single data line.
•Upgrade of DS1990 allows multiple Serial Number
iButtons to reside on a common bus
•Unique 48-bit serial number
•Low-cost electronic key for access control
•8-bit CRC for checking data integrity
•Can be read in less than 5 ms
•Operating temperature range of -40°C to +85°C
