             DATA I/O ANNOUNCES THIRD QUARTER 2004 FINANCIAL RESULTS

Redmond, WA. (Oct. 22, 2004) - Data I/O Corporation (NASDAQ:  DAIO), the leading
provider of manual and automated  device  programming  systems,  today announced
financial results for the third quarter ended Sept. 30, 2004.

Revenues  were $7.8 million,  up 12.6 percent from the $6.9 million  reported in
the second  quarter of 2004.  Third  quarter  gross  margins  increased  to 54.5
percent,  up from the 50.9  percent  reported in the prior  quarter.  The higher
gross  margins were  primarily a result of increased  direct sales in Europe and
Asia, a more favorable product mix and material cost savings.

In accordance with U.S.  generally  accepted  accounting  principles (GAAP), net
income for the third  quarter of 2004 was  $93,000 or $0.01 per share,  compared
with net income of  $104,000  or $0.01 per share in the second  quarter of 2004.
The company  took a  restructuring  charge of $432,000 or $0.05 per share during
the third  quarter,  related to a reduction in the work force  announced Aug. 2,
2004.  Excluding the restructuring  charge,  the company's  operating income was
7.3% of sales, in line with the company's expectations.

Total cash and short-term  investments  were $6.2 million at Sept. 30, 2004. The
company remains debt-free.

"We are pleased  with our  continued  growth and the fact that we  achieved  our
highest quarterly  revenues since the fourth quarter of 2000 while recording our
eighth consecutive quarter of profitability," said Fred Hume, president and CEO.
"We saw stronger customer activity from Asia, which remained our largest overall
revenue contributor. We believe this growth continues to validate our investment
in that region, which is the fastest growing manufacturing center in the world.

"We began  revenue  shipments of our new  in-systems  programming  (ISP) product
solution to a major industrial controls manufacturer in the U.S. Initially,  our
ISP solution will focus on  applications  and devices that use access methods to
the devices  that are not  currently  supported by JTAG tools  vendors.  The new
product  satisfies  an  unmet  need  for  an ISP  solution  that  can be  easily
integrated with other test products in a manufacturing environment," Hume said.

Guidance  for the Fourth  Quarter
Data I/O currently  expects that  financial  results for the fourth quarter will
generally be in line with operating results for the third quarter.
