LOTNUM4 - Lot Number Register 4
LOTNUM5 - Lot Number Register 5
WAFNUM - Wafer Number Register
COORDX0 - Wafer Coordinate X Register 0
• Bit 7:0 - LOTNUM4[7:0] - LOT Number Byte 4
This byte contains byte 4 of the LOT number for the device.
• Bit 7:0 - LOTNUM5[7:0] - LOT Number Byte 5
This byte contains byte 5of the LOT number for the device.
• Bit 7:0 - WAFNUM[7:0] - Wafer Number
This byte contains the wafer number for each device. Together with the LOT number and wafer
coordinates this gives an unique identifier or serial number for the device.
COORDX0, COORDX1, COORDY0 and COORDY1 contains the wafer X and Y coordinates for
each device. Together with the LOT number and wafer number this gives an unique identifier er
or serial number for each devicei
• Bit 7:0 - COORDX0[7:0] - Wafer Coordinate X Byte 0
This byte contains byte 0 of wafer coordinate X for the device.
