1. A light sensor package comprising:

  • an enclosure having a window for receiving light, the enclosure admitting at least a power connection pad, a ground connection pad, and an input/output pad;

    an exposed light transducer disposed within the enclosure, the exposed light transducer operative to accumulate charge in proportion to light received through the window incident on the exposed light transducer over an integration period;

    a light-to-pulse circuit in communication with the exposed light transducer, the light-to-pulse circuit operative to output a pulse on the output pin, the pulse width based on the charge accumulated by the exposed light transducer over the integration period; and

    a nonvolatile memory within the enclosure for storing data from which calibration data may be obtained for the light sensor package.
