            DATA I/O ANNOUNCES SECOND QUARTER 2005 FINANCIAL RESULTS

Redmond, Wash., July 28, 2005 - Data I/O Corporation (NASDAQ: DAIO), the leading
provider of manual and automated  device  programming  systems,  today announced
financial results for the quarter ended June 30, 2005.

Revenues were $6.6 million, compared with $6.7 million in the first quarter of
2005. Gross margins in the second quarter of 2005 were 59.2 percent, compared
with 59.6 percent in the prior quarter.

In accordance with U.S.  generally  accepted  accounting  principles (GAAP), net
income in the second  quarter of 2005 was  $53,000 or $0.01 per share,  compared
with net income of $39,000 in the first quarter of 2005.

Total cash and  short-term  investments  were $4.6 million at June 30, 2005. The
company remains debt-free.

"During   the   second   quarter,    we   began   regular   shipments   of   our
ImageWriter(TM)200,  and have  populated the sales  channels with  demonstration
systems as part of its market launch," said Fred Hume,  president and CEO. "Data
I/O's  ImageWriter(TM)  in-systems  programming solution is targeted to users of
programmable  microcontrollers in industrial controls and automotive electronics
manufacturers,  a customer  group that has seen  continued  growth over the past
year. We will be adding new options and  capabilities to the ImageWriter  family
in the third and fourth quarters of 2005."

"We also shipped our first  PS-588(TM)  product during the second  quarter.  The
PS-588  provides  our  customers a much higher  level of  throughput  for volume
programming than previously available at a lower cost per part. We expect to see
continued growth in automated programming product sales in the quarters to come.

"In  addition,  we introduced  High  Performance  Socket (HPS)  Adapters for our
Pro-LINE  RoadRunner(TM) and PS-FlashCORE(TM)  automated programming systems and
for our FlashPAK(TM) desktop programmer.  These adapters are designed for use in
low- to-medium volume production environments,  where continuous uptime and high
programming yields are required to maximize production outputs," he said.

"We have  completed the  operations  transition  and now expect to see increased
revenues  from our  programming  service  operation  in Brazil,  which  provides
programming  support for a wireless  manufacturer  there.  Data I/O continues to
have a strong manufacturing presence at other emerging electronics manufacturing
centers in China, Korea, Mexico and Eastern Europe," said Hume.

Third Quarter 2005 Guidance
Data I/O currently expects that revenues in the third quarter of 2005 will grow
modestly over the second quarter, with gross margins expected to be in line with
the previous quarter.
