DESCRIPTION
The DS1624 consists of a digital thermometer and 256 bytes of E2 memory. The thermometer provides 13-bit temperature readings which indicate the temperature of the device. The E2 memory allows a user to store frequency compensation coefficients for digital correction of crystal frequency due to temperature. Any other type of information may also reside in this user space.

FEATURES
■ Temperature measurements require no external components
■ Measures temperatures from -55°C to +125°C in 0.03125°C increments.
   Fahrenheit equivalent is -67°F to +257°F in 0.05625°F increments
■ Temperature is read as a 13-bit value (two byte transfer)
■ Converts temperature to digital word in 1 second (max)
■ 256 bytes of E2 memory on board for storing information such as
   frequency compensation coefficients
■ Data is read from/written via a 2-wire serial interface (open drain I/O lines)
■ Applications include temperature compensated
   crystal oscillators for test equipment and radio systems
■ 8-pin DIP or SOIC packages
