3 Device Markings

Figure 3-1 provides examples of the 2834x 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 3-1. Some prototype devices may have markings different from those illustrated. Figure 3-2 shows the device nomenclature.
