DS1973 - 4-kbit EEPROM iButton

General Description

The DS1973 4-kbit 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.

Key Features

  • 4096 bits Electrically Erasable Programmable Read Only Memory (EEPROM) Overdrive mode boosts communication speed to 142 kbits per second 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 Chip-.
