            DATA I/O ANNOUNCES SECOND QUARTER 2004 FINANCIAL RESULTS

Redmond, WA. (Aug. 3, 2004) - Data I/O Corporation  (NASDAQ:  DAIO), the leading
provider of manual and automated  device  programming  systems,  today announced
financial results for the second quarter ended June 30, 2004.

Revenues for the second quarter were $6.9 million, compared with $6.8 million in
the first  quarter  of 2004.  Second  quarter  gross  margins  were 51  percent,
compared  with 54 percent in the prior  quarter.  The lower gross  margins  were
primarily a result of more  indirect  sales than direct sales in the quarter,  a
product mix shift to somewhat lower margin  products and  unfavorable  labor and
overhead variances associated with a reduction in inventory.

In accordance with U.S.  generally  accepted  accounting  principles (GAAP), net
income for the second quarter of 2004 was $104,000, or $0.01 per share, compared
with net income of $296,000 or $0.04 per share in the first  quarter of 2004.  A
restructuring  related  charge of $70,000 or $0.01 per share was included in the
second quarter results.

Total cash and  short-term  investments  were $5.6 million at June 30, 2004. The
company remains debt-free.

"We are pleased with our continued progress in the second quarter, which was our
seventh  consecutive  quarter of profitability,"  said Fred Hume,  president and
CEO.  "Orders were higher than at any time since the fourth quarter of 2000, and
we saw many repeat orders from existing customers, a validation of our excellent
technology and customer relationships.

"Orders from Asia increased  during the second quarter;  in fact, that region is
now the largest  overall  contributor  to the company.  We expect this growth to
continue, particularly as a result of our investments in China. We began revenue
shipments of the PS288FC, an automated  programming  solution that we introduced
at the end of the first quarter. The PS288FC offers a superior price/performance
position for certain classes of devices for many customers, particularly in Asia
where we see the largest potential for growth.  Based on our FlashCore family of
modular automated programmers,  the PS288FC is completely compatible with any PS
system."

Guidance for the Third Quarter
Data I/O  currently  expects  to see  revenue  growth  in the third  quarter  of
approximately five percent.  The company expects to take a restructuring  charge
of approximately  $500,000 in the third quarter,  related primarily to workforce
reductions.  The company expects that workforce  reductions,  most of which were
effective Aug. 2, 2004, and other margin  improvement  initiatives will increase
net  income  by  approximately  $1.2  million  per  year.  As a  result  of  the
restructuring  actions,  Q3 GAAP net income will remain relatively flat with the
second quarter.
