Table 2–57 lists the flash memory 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 the 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) measures both the

voltage and current for several specific board rails. The power utilization is displayed

in a GUI that graphs power consumption versus time.
