San Jose, Calif. and Dublin, Ireland - November 23,
2000 - Parthus Technologies PLC (Nasdaq: PRTH, LSE: PRH), a leading
developer of semiconductor intellectual property (IP) for the mobile
Internet market, today announced at Electronica 2000 in Munich, Germany,
that µ-blox, a provider of complex digital and RF electronic system design
for OEM applications, has signed a licensing and royalty agreement for the
Parthus NavStream™ GPS platform. Fabrication of the GPS technology
will be carried out by Atmel Corporation (NASDAQ: ATML), a worldwide
leader in the design, manufacturing and marketing of advanced
semiconductors, including advanced logic, nonvolatile memory, mixed signal
and RF integrated circuits.

As part of the agreement, µ-blox will deploy the Parthus
NavStream 1000 baseband and radio platform to its global network of
partners and customers that includes several leading mobile phone
manufacturers. µ-blox is deploying the technology for use in both mobile
devices and road-tolling applications across Europe. Atmel, as well as
implementing and fabricating the chipsets, also has the option to
distribute the chipsets in its own right.

In Switzerland, µ-blox has been chosen as the sole supplier
of GPS technology into every Swiss-registered truck. This innovative
road-tolling system collects fees from truck owners based on their
location. So far, 65,000 trucks in the country have been deployed with the
technology and µ-blox has plans to expand the scheme beyond Switzerland.

GPS (Global Positioning System) is poised to play a critical
role in the mobile Internet arena. GPS utilizes information from
satellites and wireless networks to instantly locate any mobile device to
within 5-20 meters. A recent U.S. Federal Communications Commission (FCC)
mandate has dictated that by October 1, 2001, all cellular carriers in the
U.S. must be able to instantly locate cellular callers to emergency 911
services. GPS is currently the only technology that provides consistent
and accurate positioning to satisfy the FCC's requirement.

GPS also offers many commercial opportunities to wireless
operators through 'location-based m-Commerce'. Operators can sell many
unique services including real-time driving directions, traffic
information and personalized concierge services, such as locating nearby
restaurants, stores, ATMs and places of interest. As GPS becomes more
common in cars and mobile phones new uses will be possible such as
automated road tolling and parking fees based on location, and asset
protection - if a car or phone is stolen, it will be possible to locate it
over the Internet.

"We consider GPS to be an extremely important application
that will be included in next generation wireless devices," said Claus
Habiger, director of sales and marketing at µ-blox. "We chose Parthus'
NavStream platform as it leads the industry in the four critical areas for
implementing GPS in mobile phones - low cost, low power consumption,
pinpoint accuracy and noise immunity. By leveraging the considerable
technical expertise at Parthus, we are able to deliver a workable GPS
solution in a rapid time frame that is easily deployed in handheld
devices."

"GPS is a cornerstone technology of next generation mobile
Internet solutions ranging from automotive navigation systems to wireless
information devices. GPS offers endless commercial opportunities to
wireless operators through 'location-based m-Commerce'," said Bill McLean,
vice president of global sales at Parthus. "By licensing our NavStream
technology to key technology companies like µ-blox and Atmel, the promise
of multi-function mobile Internet devices becomes a reality."
