Exhibit 31.2

                                  CERTIFICATION


     I, Andrew M. Caggia, certify that:

               1. I have reviewed this quarterly report on Form 10-Q of Standard
     Microsystems Corporation;

               2. Based on my knowledge, this report does not contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this report;

               3. Based on my  knowledge,  the financial  statements,  and other
     financial  information  included  in this  report,  fairly  present  in all
     material respects the financial  condition,  results of operations and cash
     flows of the  registrant  as of, and for,  the  periods  presented  in this
     report;

               4.  The  registrant's   other   certifying   officer  and  I  are
     responsible  for  establishing  and  maintaining  disclosure  controls  and
     procedures (as defined in Exchange Act Rules 13a-15 (e) and 15d-15 (e)) for
     the registrant and have:

               a) Designed such disclosure  controls and  procedures,  or caused
     such   disclosure   controls  and  procedures  to  be  designed  under  our
     supervision,   to  ensure  that  material   information   relating  to  the
     registrant, including its consolidated subsidiaries, is made known to us by
     others within those entities,  particularly during the period in which this
     report is being prepared;

               b) Evaluated the  effectiveness  of the  registrant's  disclosure
     controls and procedures and presented in this report our conclusions  about
     the effectiveness of the disclosure controls and procedures,  as of the end
     of the period covered by this report based on such evaluation; and

               c)  Disclosed  in this  report  any  change  in the  registrant's
     internal  control  over  financial   reporting  that  occurred  during  the
     registrant's  most recent fiscal  quarter (the  registrant's  fourth fiscal
     quarter in the case of an annual report) that has materially  affected,  or
     is  reasonably  likely to  materially  affect,  the  registrant's  internal
     control over financial reporting; and

               5.  The  registrant's   other  certifying   officer  and  I  have
     disclosed,  based on our most recent  evaluation  of internal  control over
     financial reporting,  to the registrant's  auditors and the audit committee
     of  the  registrant's   board  of  directors  (or  persons  performing  the
     equivalent function):

               a) All significant  deficiencies  and material  weaknesses in the
     design or operation of internal control over financial  reporting which are
     reasonably  likely to adversely affect the registrant's  ability to record,
     process, summarize and report financial information; and

               b) Any fraud,  whether or not material,  that involves management
     or other employees who have a significant role in the registrant's internal
     control over financial reporting.
