DS2401+

The DS2401+ is a silicon serial number IC in 3 pin TO-92 package. This enhanced silicon serial number is a low cost electronic registration number that provides an absolutely unique identity which can be determined with a minimal electronic interface (typically a single port pin of a microcontroller). The DS2401 consists of factory lasered, 64bit ROM that includes unique 48bit serial number, 8bit CRC and 8bit family code (01h). Data is transferred serially via 1-Wire protocol that requires only single data lead and ground return. Power for reading and writing the device is derived from data line itself with no need for an external power source. It is fully reverse compatible with DS2400 but provides additional multi drop capability that enables many devices to reside on a single data line.

• Guaranteed unique 64bit ROM ID chip for absolute traceability
• 1-wire interface lowers cost and interface complexity
• Multiple DS2401 devices can reside on a common 1-wire net
• Built-in multidrop controller ensures compatibility with other 1-wire net products
• Reduces control, address, data and power to a single pin and communicates at up to 16.3Kbps
• Presence pulse acknowledges when reader first applies voltage
• Wide voltage and temperature operating ranges enables robust system performance
• Extended supply voltage range from 2.8V to 6.0V
• Zero standby power required
• Operating temperature range from -40°C to 85°C
