   San Jose, CA, January 31, 2008 - Micrel, Incorporated (Nasdaq NM: MCRL),
an industry leader in analog, high bandwidth communications and Ethernet IC
solutions, today announced financial results for the fourth quarter and
fiscal year ending December 31, 2007.

   Revenues for the fourth quarter totaled $64.6 million, compared to
$65.2 million for the third quarter and $64.5 million posted in the year-ago
period.  Fourth quarter GAAP net income was $8.4 million, or $0.11 per
diluted share.  This compares with third quarter 2007 GAAP net income of $9.4
million, or $0.12 per diluted share, and GAAP net income of $8.8 million, or
$0.11 per diluted share, in the year ago period.

   Fourth quarter 2007 non-GAAP net income was $9.4 million or $0.12 per
diluted share.  This compares to non-GAAP net income of $10.5 million, or
$0.14 per diluted share in the previous quarter and $10.2 million, or $0.13
per diluted share in the fourth quarter of 2006.  Non-GAAP results exclude
the impact of revenues and cost of revenues related to intellectual property
settlements, stock-based compensation expense, other operating income and
expense items, restructuring expenses, other income related to litigation
settlements and their related tax effects.  A reconciliation of the GAAP net
income to non-GAAP net income is provided in the financial tables of this
press release.

   For the year ended December 31, 2007, revenues were $258.0 million,
compared with $276.3 million in 2006.  GAAP net income for fiscal 2007
increased 15.8% to $44.4 million, or $0.57 per diluted share, compared with
GAAP net income of $38.3 million, or $0.46 per diluted share in 2006.  GAAP net
income in 2007 was the second highest annual result in the Company's history.
Included in 2007 net income was a $15.5 million pre-tax gain associated with
a first quarter legal settlement, which after income taxes, is equivalent to
$0.13 per diluted share.  Non-GAAP net income in 2007 was $39.5 million, or
$0.51 per diluted share, compared with non-GAAP net income of $45.3 million,
or $0.55 per diluted share in 2006.  Micrel's 2007 gross margin of 57%
matched the second highest level in the Company's history.

   "Micrel's solid 2007 earnings and strong cash flows from operations
continued to bolster the Company's financial strength throughout the year,"
stated Ray Zinn, president and CEO of Micrel.  "Momentum generated from
recent design wins coupled with a broad array of new products released during
2007 gives Micrel a strong platform to generate growth in revenues and net
income going forward.  Solid cash flows from operations of $67.8 million
during 2007 enabled the repurchase of 5.5 million shares of common stock and
the commencement of a dividend payment to shareholders, representing our
confidence in the Company's operating performance and commitment to enhancing
shareholder value."

   Outlook
   -------
   Fourth quarter bookings were below third quarter levels resulting in a
book-to-bill ratio of less than one.  Order lead times remain very short,
further limiting visibility into end demand and making it difficult to
predict future revenues.  A relatively high proportion of revenue must still
be booked and shipped within the quarter to OEM customers, or resold through
the Company's distributors.  For the first quarter of 2008, the Company
estimates revenues will be lower by 1% to 4% compared to the fourth quarter,
and GAAP earnings per diluted share will be approximately $0.10.

   Zinn concluded, "Evidence of a slowing U.S. economy has increased the
investment community's concerns about the business outlook for the
semiconductor industry. In addition, the first quarter is typically a
seasonally weak quarter for the semiconductor industry.  However, we are
encouraged by the relatively normal booking levels we have experienced in
January, and to-date, we have seen no significant change in our customer's
order patterns."

   Dividend
   --------
   The Company announced today that Micrel's Board of Directors has
authorized a quarterly dividend payment of $0.03 per share of common stock.
The payment will be made on February 26, 2008 to shareholders of record as of
February 11, 2008.

   Non-GAAP Reporting
   ------------------

   The Company presents non-GAAP financial measures only because investors
and financial analysts use non-GAAP results in their analysis of historical
results and projections of the Company's future operating results.  The
Company's management uses non-GAAP measures on a limited basis, primarily for
employee performance-based compensation.  In order to facilitate the
computation of non-GAAP results for the financial analyst community and
investors, the Company makes reference to non-GAAP net income and earnings
per share.  These non-GAAP results exclude the impact of revenues and cost of
revenues related to intellectual property settlements, stock-based
compensation expense, other operating income and expense items, restructuring
expenses, other income related to litigation settlements and their related
tax effects.  Micrel references those results to allow a better comparison of
results in the current period to those in prior periods and to provide
insight to the Company's on-going operating performance after exclusion of
these items.  The Company has reconciled such non-GAAP results to the most
directly comparable GAAP financial measures in the financial tables at the
end of this press release.

   Reference to these non-GAAP results should be considered in addition to
results that are prepared under current accounting standards but should not
be considered a substitute for results that are presented in accordance with
GAAP.  It should also be noted that Micrel's non-GAAP information may be
different from the non-GAAP information provided by other companies.

(1) Non-GAAP shares have been adjusted from diluted outstanding shares calculated under FAS123R.

(2) Non-GAAP results were reached by excluding revenues and cost of revenues related to intellectual property
     settlements, stock-based compensation expense, other operating income or expense items,
     restructuring expenses, other income related to litigation settlements and their related tax-effects.
     Non-GAAP results are presented to supplement our GAAP consolidated financial statements to allow a better
     comparison of results in the current period to those in prior periods and to provide meaningful insight to the
     Company's on-going operating performance after exclusion of these items.

(1)  On January 1, 2007, Micrel adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income
  Taxes ("FIN 48"). Implementation of FIN 48 resulted in a $2.1 million reclassification from current
  taxes payable to long-term taxes payable and an additional $2.5 million was reclassified from current
  taxes payable to reduce long term deferred tax assets.
