LOTNUM0 – Lot Number Register 0
LOTNUM1 – Lot Number Register 1
LOTNUM2 – Lot Number Register 2
LOTNUM3- Lot Number Register 3
LOTNUM0, LOTNUM1, LOTNUM2, LOTNUM3, LOTNUM4 and LOTNUM5 contain the lot num-
ber for each device. Together with the wafer number and wafer coordinates this gives a serial
number for the device.
• Bit 7:0 – LOTNUM0[7:0]: Lot Number Byte 0
This byte contains byte 0 of the lot number for the device.
• Bit 7:0 – LOTNUM1[7:0]: Lot Number Byte 1
This byte contains byte 1 of the lot number for the device.
• Bit 7:0 – LOTNUM2[7:0]: Lot Number Byte 2
This byte contains byte 2 of the lot number for the device.
• Bit 7:0 – LOTNUM3[7:0]: Lot Number Byte 3
This byte contains byte 3 of the lot number for the device.
