         Re:  Broadcom Corporation - Registration Statement on Form S-4


Ladies and Gentlemen:

     In connection with a registration statement on Form S - 4 to be filed by
Broadcom Corporation, a California corporation (the "Company"), with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Securities Act"), on February 20, 2004 (the
"Registration Statement"), you have requested our opinion with respect to the
matters set forth below.

     You have provided us with a draft of the Registration Statement, in the
form in which it will be filed, which includes a prospectus (the "Prospectus").
The Prospectus provides that it will be supplemented in the future by one or
more supplements to the Prospectus (each, a "Prospectus Supplement"). The
Prospectus, as supplemented by various Prospectus Supplements, will provide for
the offering by the Company of up to 30,000,000 shares of the Company's Class A
common stock, $0.0001 par value per share (the "Securities").

     In our capacity as your special counsel in connection with such
registration, we are familiar with the proceedings taken and proposed to be
taken by the Company in connection with the authorization and issuance of the
Securities, and, for the purposes of this opinion, have assumed such proceedings
will be timely completed in the manner presently proposed. In addition, we have
made such legal and factual examinations and inquiries, including an examination
of originals or copies certified or otherwise identified to our satisfaction of
such documents, corporate records and instruments, as we have deemed necessary
or appropriate for purposes of this opinion. In our examination, we have assumed
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals, and the conformity to authentic original documents of all
documents submitted to us as copies. As to facts material to the opinions,
statements and assumptions expressed herein, we have, with your consent, relied
upon oral or written statements and representations of officers and other
representatives of the Company and others. We have not independently verified
such factual matters.

     We are opining herein as to the effect on the subject transaction only of
the federal laws of the United States and the Corporations Code of the State of
California, and we express no

opinion with respect to the applicability thereto, or the effect thereon, of the
laws of any other jurisdiction or, in the case of California, any other laws, or
as to any matters of municipal law or the laws of any other local agencies
within any state.

     Subject to the foregoing, it is our opinion that, as of the date hereof,
the Company has authority pursuant to its Amended and Restated Articles of
Incorporation to issue up to an aggregate of 800,000,000 shares of the
Securities. Upon adoption by the Board of Directors of the Company of a
resolution in form and content as required by applicable law authorizing the
issuance of shares of the Securities (with such shares, together with all shares
previously issued or reserved for issuance and not duly and lawfully retired,
not exceeding an aggregate of 800,000,000 shares) and upon issuance and delivery
of and payment of legal consideration in excess of the par value thereof for
such shares in the manner contemplated by the Registration Statement, the
Prospectus, the related Prospectus Supplement(s) and by such resolution, such
shares of the Securities will be validly issued, fully paid and nonassessable.

     We assume for purposes of this opinion that the Company has been duly
incorporated and is validly existing as a corporation under the laws of the
State of California and has the corporate power and authority to issue and sell
the Securities.

     We consent to your filing this opinion as an exhibit to the Registration
Statement and to the reference to our firm under the caption "Validity of the
Securities" in the Prospectus included therein.


                                Very truly yours,


                               /s/ Latham & Watkins LLP
