    AUSTIN, Texas--(BUSINESS WIRE)--Jan. 3, 2007--Cirrus Logic Inc.
(Nasdaq:CRUS), a leading designer of high-precision analog,
mixed-signal and embedded integrated circuits, today announced that it
has purchased all of the outstanding stock of Caretta Integrated
Circuits, a fabless integrated circuit (IC) design company based in
Shanghai. In connection with the acquisition, Cirrus Logic paid
Caretta's stockholders $10.5 million in cash and has agreed to pay
certain employees a potential earn-out based on financial performance
over the next two years.

    "Acquiring Caretta expands and diversifies Cirrus Logic's
expertise in analog IC technology, enables increased development of
China-originated intellectual property, and provides us with a
stronger, long-term strategic position to grow in China by developing
our China-based organization," said David D. French, president and
chief executive officer, Cirrus Logic. "This acquisition further
strengthens Cirrus Logic's growth efforts toward expanding segments of
the analog, mixed-signal IC market."

    Founded in 2004, Caretta has focused its initial IC development
efforts on a battery protection IC for the single-cell lithium ion
battery market. With offices in Shanghai and Shenzhen, Caretta employs
37 people, including 30 engineers.

    The company expects to recognize a one-time charge of $1 million
to $4 million in the December quarter of 2006. This transaction is
expected to be neutral to earnings per share in calendar 2007.
