What does NRND really mean and what should the take away be if comparable or replacement devices have the same longevity commitment?
NRND typically means that we anticipate or that we've seen a decline in customer sales for a given device and thus it is unlikely that we will continue to produce this device beyond our longevity commitment.
Many of our 8-bit devices have the same longevity commitments but are in full production and do not bare the NRND label. This usually indicates that the device continues to be purchased in large quantities by our distributors/customers and as of now, the device is in continuous production to keep up with demand. This does not guarantee production beyond our longevity commitment, as we cannot predict the market through that date, but the larger customer base is a good indicator that we may continue to support this device beyond our initial commitment.
