Hello Paolo,
Thank you for contacting Cypress Semiconductor.
It appears you may have purchased the AM29LV640DU-90RWHI from an unauthorized distributor,
third party vendor or reseller, as these additional markings are not recognized as valid standard
markings from the factory. These AM29LV640DU FLASH devices may have been refurbished or
possibly customer returns or RMA. There appears to be a checksum that is marked on the device.
The checksum "CS = BCD4h" indicates that this device has already been programmed by the
previous user/owner of this device.
The additional markings are not recognized as a valid standard markings from the factory.
Best regards,
