Notes: 1. See Figure 5 for undershoot and overshoot voltages.
2. Not tested. Guaranteed by design.
3. Measured for 1.1 V core at 25°C junction temperature.
4. The typical power values were calculated using a power calculator configured for two cores performing an EFR code with the
device running at the specified operating frequency and a junction temperature of 25°C. No peripherals were included. The
calculator was created using CodeWarrior^® 2.5. These values are provided as examples only. Power consumption is
application dependent and varies widely. To assure proper board design with regard to thermal dissipation and maintaining
proper operating temperatures, evaluate power consumption for your application and use the design guidelines in Chapter 4 of
this document and in MSC8102, MSC8122, and MSC8126 Thermal Management Design Guidelines (AN2601).
