Abstract
Aspects of the invention may comprise an integrated circuit comprising a memory, a temperature sensor, a crystal, and a communication module. Data stored in the memory may indicate a frequency of the crystal as a function of temperature and/or time. The memory may be writable via the communication module. Data stored in the memory of the integrated circuit may be updated based on an age and/or time of use of the integrated circuit. The time of use may be one or both of: how long the crystal has been oscillating since its most-recent start up, and how long the crystal has been in use over its lifetime. An electronic device may calculate a frequency of an oscillating signal output by the crystal based on a temperature indication from the temperature sensor and data read from the memory of the integrated circuit.
