Table 2–43 lists the flash component reference and manufacturing information.
Power Supply
The development board's power is provided through a laptop style DC power input.
The input voltage must be in the range of 14 V to 20 V. The DC voltage is then stepped
down to various power rails used by the components on the board and installed into
the HSMC connectors.
An on-board multi-channel analog-to-digital converter (ADC) is used to measure both
the voltage and current for several specific board rails. The power utilization is
displayed using a GUI that can graph power consumption versus time.
Power Distribution System
Figure 2–10 shows the power distribution system on the development board.
Regulator inefficiencies and sharing are reflected in the currents shown, which are
conservative absolute maximum levels.
