Obsolescence of 56 QFN (8x8x1.0mm) punch singulation products in HUB family.

Question: Is CY7C65640A-LFXC obsolete? What is the drop-in-replacement? Are all parts in HUB family in the same package obsolete?

 

Answer:

Yes, the CY7C65640A-LFXC is obsolete. The drop in replacement part of CY7C65640A-LFXC is CY7C65640A-LTXC. A drop-in replacement is defined as a product that is pin-to-pin and function/feature compatible with the obsolete product.

 

Please note that both are from the same die and same package. The only difference is in the singulation. Cypress is moving from punch singulation to saw singulation. The saw singulation process is more stable and supports a more reliable supply source for our customers.

Yes, all parts in HUB family in the same package are obsolete. Find below the list of the obsolete and their drop in replacement parts in HUB family.
