             DATA I/O ANNOUNCES FIRST QUARTER 2005 FINANCIAL RESULTS

Redmond,  Wash.,  April 27,  2005 - Data I/O  Corporation  (NASDAQ:  DAIO),  the
leading  provider of manual and  automated  device  programming  systems,  today
announced financial results for the first quarter ended March 31, 2005.

Revenues were $6.7 million,  compared with $5.8 million in the fourth quarter of
2004.  Gross margins in the first  quarter of 2005 were 59.6  percent,  compared
with 53.8 percent in the prior quarter.  The higher gross margins were primarily
a result of more direct than indirect sales in the quarter,  a favorable product
mix,  higher  margins on  aftermarket  products,  and lower  labor and  overhead
expenses related to the company's restructuring in 2004.

In accordance with U.S.  generally  accepted  accounting  principles (GAAP), net
income in the first  quarter of 2005 was  $39,000,  compared  with a net loss of
$584,000 in the fourth quarter of 2004.

Total cash and short-term  investments  were $5.1 million at March 31, 2005. The
company remains debt-free.

"We recently  announced  the  expansion  of our  strategic  alliance  with Intel
Corporation," said Fred Hume,  president and CEO. "Intel opened a new Programmer
Evaluation  Lab  in  the  Philippines,   which  includes  a  Data  I/O  FlashPAK
programming  system.  The new lab  increases  our  ability to support our common
customers in Asia," he said.

"We began revenue shipments of the ImageWriter(TM) during the first quarter, and
also announced  that our  ImageWriter  product  supports the Atmel AVR family of
flash  microcontrollers  already mounted on a circuit board.  The ImageWriter is
based on an open architecture  that enables seamless  integration with automated
test and  manufacturing  systems,  enabling  manufacturers  of  consumer  goods,
automotive equipment and industrial products to reduce costs and rapidly deliver
products  to  market.  We  expect  to see  continued  growth  in  our  in-system
programming product sales in the quarters to come," said Hume.

"In addition,  we signed a  distribution  agreement with Accelonix UK, a leading
supplier of test and measurement  equipment in Great Britain.  Accelonix UK will
be the  exclusive  distributor  for Data I/O's  products  in Great  Britain  and
Northern Ireland.  We are excited about the compelling  market  opportunities in
this region," said Hume.

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