All devices in the PSoC 3 CY8C34 family comply to RoHS-6 specifications, demonstrating the commitment by Cypress to lead-free
products. Lead (Pb) is an alloying element in solders that has resulted in environmental concerns due to potential toxicity. Cypress
uses nickel-palladium-gold (NiPdAu) technology for the majority of leadframe-based packages.
A high level review of the Cypress Pb-free position is available on our website. Specific package information is also available. Package
Material Declaration data sheets (PMDDs) identify all substances contained within Cypress packages. PMDDs also confirm the
absence of many banned substances. The information in the PMDDs will help Cypress customers plan for recycling or other “end of
life” requirements.
