Change Description:
Copper (Cu) bond wire usage
In order to increase manufacturing flexibility and to ensure a long-term continuity of supply, Atmel will
manufacture 8-lead PDIP and 5-lead SOT23 packages using both gold (Au) and copper bond (Cu) wires.
Atmel reserves the right to ship devices with either gold or copper bond wires. The change does not impact
reliability, soldering profiles or electrical characteristics. Qualification data is available upon request.
