DS1973-F3+

The DS1973-F3+ is a 4Kb EEPROM iButton in F3 MicroCan package. This iButton is a rugged read/write data carrier that identifies and stores relevant information about product or person to which it is attached. This information can be accessed with minimal hardware for example a single port pin of a micro-controller. The DS1973 consists of a factory lasered registration number that includes a unique 48bit serial number, an 8bit CRC and an 8bit family code (23H) plus 4096bits of EEPROM. Power to program and read DS1973 is derived entirely from the 1-wire communication line. Memory is organized as sixteen pages of 256 bits each. The 64bit registration number provides a unique identity which allows for absolute traceability. Button shape is self aligning with cup shaped probes, durable stainless steel case engraved with registration number withstands harsh environments. It is easily affixed with self stick adhesive backing, latched by its flange or locked with a ring pressed onto its rim.

• Overdrive mode boosts communication speed to 142Kbps, multidrop controller for MicroLAN
• 256bit scratchpad ensures integrity of data transfer, data can be accessed while affixed to object
• Memory partitioned into 256bit pages for packetizing data
• Reduces control, address, data and power to a single data pin
• 8bit family code specifies DS1973 communication requirements to reader
• Reads and writes over a wide voltage range of 2.8V to 6V from -40°C to +85°C
• Digital identification and information by momentary contact
• Chip based data carrier compactly stores information
• Economically communicates to bus master with a single digital signal at 16.3Kbps
• Presence detector acknowledges when reader first applies voltage
