This section describes the DC electrical characteristics for the MSC8122. The measurements in Table 5 assume the
following system conditions:
TA = 25 °C
VDD =
— 300/400 MHz 1.1 V nominal = 1.07–1.13 VDC
— 400 MHz 1.2 V nominal = 1.14–1.26 VDC
— 500 MHz 1.2 V nominal = 1.16–1.24 VDC
VDDH = 3.3 V ± 5% VDC
GND
= 0 VDC
Note:
The leakage current is measured for nominal VDDH and VDD.

Notes:
1.
See Figure 5 for undershoot and overshoot voltages.
2.
Not tested. Guaranteed by design.
3.
Measured for 1.2 V core at 25°C junction temperature.
4.
The typical power values were measured using an EFR code with the device running at a junction temperature of 25°C. No
peripherals were enabled and the ICache was not enabled. The source code was optimized to use all the ALUs and AGUs and
all four cores. It 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).
