Circuitry for monitoring an optoelectronic device includes memory, including one or more memory arrays for storing information related to the optoelectronic device and analog to digital conversion circuitry for: receiving a plurality of analog signals from the optoelectronic device; converting the received analog signals into digital values; and storing the digital values in memory mapped locations within the memory. The analog signals correspond to operating conditions of the optoelectronic device. The circuitry further includes a memory interface for allowing a host device to read from and write to memory mapped locations within the memory in accordance with commands received from a host device. The memory interface allows the host device to read the digital values corresponding to operating conditions of the optoelectronic device from the memory mapped locations within the memory.
