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
or through the PCI Express edge connector. The DC voltage is 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.
Table 2–58 lists the maximum allowed draws of the power input.
Power Distribution System
The power tree minimizes power board space for PCI Express board requirements
and gives the maximum power under 5.5 A for a 12 V PCI Express input and 3.0 A for
a 3.3 V PCI Express rail. The switching regulators are assumed to have 85% of
efficiency. Regulator inefficiencies and sharing are reflected in the currents shown,
which are conservative absolute maximum levels.
