Can you clarify if the devices were marked as "CY7C1061DV33-10ZSXI KG"?
Or the marking on the device always "CY7C1061DV33-10ZSXI" ?
The device MPN CY7C1061DV33-10ZSXIKG was created when Cypress was qualifying a new test site and the MPN was offered as intermediate sampling code.
But if you are ordering this device now the code should be CY7C1061DV33-10ZSXI.
Also, please note that the CY7C1061DV33-10ZSXI device is obsoleted now and we suggest using CY7C1061G30-10ZSXI or CY7C1061GN30-10ZSXI for your design
