Item 1.01.      Entry into a Material Definitive Agreement.

     On July 11,  2007,  Cirrus  Logic,  Inc.  (the  "Company")  entered into an
Agreement  and Plan of Merger (the  "Merger  Agreement")  with Apex  Acquisition
Company,  an Arizona  corporation  and wholly  owned  subsidiary  of the Company
("Merger  Sub"),  Apex  Microtechnology   Corporation,  an  Arizona  corporation
("Apex"),  James A. Unruh (as  Representative),  and certain Apex equityholders.
The  Merger  Agreement  provides  for the  acquisition  of  Apex by the  Company
pursuant  to the merger of Merger  Sub with and into  Apex,  with Apex being the
surviving  corporation (the "Merger").  Upon completion of the Merger, Apex will
be a direct, wholly owned subsidiary of the Company.

     Subject  to the  terms  of the  Merger  Agreement,  including  the  closing
conditions set forth therein,  the Company will pay aggregate cash consideration
of  approximately  $42 million to the Apex  equityholders,  subject to customary
closing   adjustments,   including  without  limitation   deduction  for  Apex's
outstanding   indebtedness,   transaction   expenses   and   certain   severance
obligations,  and adjustments based upon Apex's net working capital  immediately
prior to the closing date.

     The Merger Agreement  contains  customary  representations,  warranties and
covenants  of each  of the  parties  thereto,  and is  subject  to a  number  of
customary  closing  conditions.  Both  Apex and the  Company  have the  right to
terminate the Merger  Agreement  under certain  circumstances,  including if the
Merger has not been completed by August 31, 2007.

     The Merger  Agreement also provides that $6.3 million of the purchase price
will be placed into an escrow  account to indemnify the Company  against  losses
resulting  from breaches of Apex's  representations,  warranties,  covenants and
agreements,   certain   environmental   matters,   claims  regarding  dissenting
shareholders  and certain  other  matters.  In addition,  to the extent that the
escrow fund is insufficient,  Apex's  equityholders have agreed to indemnify the
Company for losses resulting from breaches of certain of Apex's  representations
and warranties,  covenants and agreements,  and certain  environmental  matters,
subject to the limitations set forth in the Merger Agreement.

     A copy of the  Merger  Agreement  is filed as Exhibit  2.1 to this  Current
Report on Form 8-K. The  descriptions of the Merger  Agreement  included in this
Current  Report on Form 8-K are  qualified  in their  entirety  by the terms and
