Power sequencing is not necessary; however, the voltage on any Input or I/O pin cannot exceed its corresponding supply voltage during power supply ramp up. The device is not sensitive to supply rise and fall times, and thus these are not specified. 2. VDD3, VDDA, and VDDS share a common ground (GNDS). Core supply and ground are VDD and GND respectively. 3. VDD3 may be operated at either 3.3V or 2.5V simply by providing that supply voltage. For those interfaces operating on this supply, this datasheet provides input and output specifications at each of these voltages. 4. VDDS & VDDA may be tied to a common power plane. VDD (core, digital supply) should have its own supply and plane. A ferrite bead may be used to supply VDDS/ VDDA from VDD. The bead should be chosen to provide a low DC resistance in order to maintain the rail voltage spec. To keep within the specified low VDDA / VDDS limit, a 0.06 Ohm (DC) resistance is the max allowable. A bead with 10 Ohm impedance provides sufficient AC block while still meeting DC resistance requirements. Grade Ambient Temperature Ground(2) Supply Voltage(4) Commercial 0°C to 70°C GND = 0V GNDS = 0V VDD = 1.2 +/- 5% VDDS = 1.2 +/- 5% VDD3(3) = 3.3 +/- 5% or 2.5V +/- 100mV VDDA = 1.2 +/- 5% Industrial -40°C to 85°C GND = 0V GNDS = 0V VDD = 1.2 +/- 5% VDDS = 1.2 +/- 5% VDD3(3) = 3.3 +/- 5% or 2.5V +/- 100mV VDDA = 1.2 +/- 5% Table 2 Recommended Temperature and Operating Voltage |
