             DATA I/O ANNOUNCES THIRD QUARTER 2005 FINANCIAL RESULTS

Redmond, Wash., Oct. 28, 2005 - 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, 2005.

Revenues were $6.6 million,  the same as in the second quarter of 2005. However,
stronger  demand for the  company's  products  resulted in  increased  unshipped
orders,  raising backlog by $1.2 million to a total of $2 million going into the
fourth  quarter.  Gross  margins in the third quarter of 2005 were 57.0 percent,
compared with 59.2 percent in the prior quarter.

In accordance with U.S.  generally  accepted  accounting  principles (GAAP), net
income in the third  quarter of 2005 was  $127,000 or $0.02 per share,  compared
with net income of $53,000,  or $0.01 per share,  in the second quarter of 2005.
The company remains debt-free.

"During the third  quarter,  our  strategy to increase our  engagement  with the
semiconductor manufacturers produced results. A large semiconductor manufacturer
purchased an initial automated programming system for factory programming in its
Asian  facility.  We continue to  strengthen  our three-way  relationships  with
semiconductor manufacturers and global customers," said Fred Hume, president and
CEO.

"In September, at an important industry show, we introduced the ImageWriter-300,
a   programming   solution   designed    specifically   for   integration   with
in-circuit-test  equipment.  The  ImageWriter-300  is a new configuration in our
ImageWriter(TM) line of In-System Programming  solutions.  This solution expands
the ImageWriter line's available market.

"We continued to make progress with our  automotive-related  accounts during the
third  quarter.  A large  automotive  electronics  manufacturer  made an initial
purchase of a Data I/O PS system. The automotive  electronics  manufacturers are
becoming  increasingly  important  to us as a  segment  for  automated  and  ISP
solutions," said Hume.

Fourth Quarter 2005 Guidance
Data I/O  currently  expects  that  revenues in the fourth  quarter of 2005 will
increase significantly over third quarter revenues.
