9.3. Device Marking of Production Devices
Line 1 is the part number; line 2 is the lot code, and line 3 is the date code. The Lot ID Code on the top side of the
device package can be used for decoding device revision information. On Si3460 devices, the silicon revision letter
is the first letter of the Lot ID Code on the second line of the device mark. Figure 8 shows how to find the Lot ID
Code on the top side of the device package for production devices.
