Restriction of Hazardous Substances (RoHS) Compliance

Cirrus Logic is actively committed to our role in protecting the environment by reducing the amount of hazardous substances in our products. As a member of JEDEC, the semiconductor standardization body of the Electronics Industries Alliance (EIA), Cirrus Logic is working with customers and suppliers to comply with industry standards.

  • The European Union has enacted legislation (Directive 2002/95/EC) effective July 1st, 2006 that restricts the use of Lead, Cadmium, Mercury, Hexavalent Chromium, Poly-Brominated Bi-Phenyls (PBB), and Poly-Brominated Di-Phenyl Ethers (PBDE) in a wide variety of electronic products and applications that are put on the market in EU member countries. Its replacement, Directive 2011/65/EU (RoHS-II) entered into force in 2011.
  • Cirrus Logic offers Pb-free product versions which fully meet the definition of RoHS compliance:

    Restricted substances are not intentionally added to the product

    The presence of any of the restricted substances does not exceed the maximum stated concentration per homogeneous material as defined by the RoHS directive and shown in the following table:
