4 Every sector is further divided into 16 subsectors with 4 KB of memory. Therefore, there are 128 (8 x 16) subsectors for the EPCQ4A device, 512 (32 x 16) subsectors for the EPCQ16A device, 1,024 (64 x 16) subsectors for the EPCQ32A device, 2,048 (128 x 16) subsectors for the EPCQ64A device, and 4,096 (256 x 16) subsectors for the EPCQ128A device.
