DS2401Z+.

The DS2401Z+ is an 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). It consists of a factory-lasered, 64-bit ROM that includes a 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 that requires only a single data lead and a ground return. Power for reading and writing the device is derived from the data line itself with no need for an external power source. This is an upgrade to the DS2400. It is fully reverse-compatible with the DS2400 but provides the additional multi-drop capability that enables many devices to reside on a single data line.

• Unique, factory-lasered and tested 64-bit registration number
• 8-bit Family code specifies DS2401 communications requirements to reader
• 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, 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
• Zero standby power required
