Dear Sirs and Mesdames:

We received the Staff's letter to Data I/O Corporation (the Company") dated December 21, 2017. As I discussed with Mr. Leslie, the Company is closed for the holidays from December 22, 2017 to January 2, 2018 and our Chief Executive Officer will be out until January 8, 2018. As a result, we would like to request an extension of ten additional days until January 12, 2018 to respond to the Staff's letter.

If you should have any questions or concerns regarding the anticipated timing of our response, please do not hesitate to contact our counsel, Kimberley Anderson of Dorsey & Whitney LLP, at (206) 903-8803.

Yours truly,

Data I/O Corporation

/s/ Joel Hatlen
