Silicon Serial Number, 2.8 V to 6 V, TO-92-3

The DS2401+T&R is a Silicon Serial Number IC in a 3 pin TO-92 Package. It is a low-cost device that generates an electronic registration number that provides an absolutely unique identity that 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 a unique 48bit serial number, 8bit CRC, and 8bit 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. The DS2401 is an upgrade and reverse compatible with the DS2400 device. The familiar TO-92 package provides a compact enclosure that allows standard assembly equipment to handle the device easily. The DS2401 is suitable for network node ID, equipment registration, PCB ID and authentication, and print cartridge authentication.

  • The pull-up voltage range is 2.8V to 6V
  • Operating temperature range from -40°C to 85°C
  • Unique 64bit ROM ID chip for absolute traceability and zero standby power required
  • 8bit family code specifies DS2401 communication requirements to the reader
  • Minimalist 1-wire interface lowers cost and interfaces complexity
  • Multiple DS2401 devices can reside on a common 1-wire net, 15µs release time, and 1µs recovery time
  • The 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 the reader first applies voltage
  • Wide voltage and temperature operating ranges enables robust system performance
