The DS1973 4Kb EEPROM iButton is a rugged read/write data carrier that identifies and stores relevant information about the 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 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (23H) plus 4096 bits of EEPROM. The power to program and read the DS1973 is derived entirely from the 1-Wire communication line. The memory is organized as sixteen pages of 256 bits each.
4096 bits Electrically Erasable Programmable Read Only Memory (EEPROM)
Overdrive mode boosts communication speed to 142kbps
256-bit scratchpad ensures integrity of data transfer
Memory partitioned into 256-bit pages for packetizing data
Reduces control, address, data and power to a single data pin
8-bit family code specifies DS1973 communication requirements to reader
Reads and writes over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C
