Jagan, So far, our major customer request is to have the same ID for backward compatibility. Therefore the IDs are the same for W25Q16C and W25Q16D. As for the 2.5V parts (W25Q80BL/W25Q16CL), they are the same die as the 3V (W25Q80BV/W25Q16CV), so the IDs are the same as well.
The differences between the pairs are not that significant. We consider them as drop-in compatible. Best Regards, Mike Chen Technical Marketing Winbond Electronics Corp.
