Table 2–31 lists the flash component reference and manufacturing information.

Power Supply

The starter board's power is provided through a laptop-style DC power input. The

input voltage must be in the range of 9

V to 16 V. The DC voltage is then stepped

down to various power rails used by the components on the board.

An on-board multi-channel analog-to-digital converter (ADC) measures 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 2–7 shows the power distribution system on the starter board. The currents

shown are conservative absolute maximum levels and reflects the regulator

inefficiencies and sharing.
