Hello all,
We've received a reel of 1,000 SRAM parts from PartMiner that were deemed counterfeit by the folks at Cypress. Due to availability issues in March we were forced to buy from this broker, even though they've screwed us in the past with counterfeit parts and I've pleaded with them not to buy from them (or any broker) again. The failure rate of the chips at initial test is about 10%. The chips in question are 256kb async SRAMS marked:
CY7C199D-10VXI
0544 G 04 637944After contacting Cypress, their response was:
"Based on the information (top marking) that you provided , our lot history verification showed that it is "not" a Cypress device. Please be guided that Cypress guarantees only parts that were bought from Cypress or authorized distributors. Attached is the official Cypress Broker Letter."
