Device Markings
Figure 1 provides an example of the F2833x and F2823x device markings and defines each of the
markings. The device revision can be determined by the symbols marked on the top of the package as
shown in Figure 1. Some prototype devices may have markings different from those illustrated. Figure 2
shows an example of the device nomenclature.
