B.1.2 Current requirements
This section lists the current requirements of the PB926EJ-S.
Powered from DC IN
Table B-2 shows the current requirements at room temperature and nominal voltage
powered from the DC IN connector. These measurements include the current drawn by
Multi-ICE, approximately 160mA at 3.3V.
Powered from J34 or PCI bus
Table B-3 shows the current requirements if the board is powered from terminal
connector J34 or the PCI bus. The maximum value refers to loading by additional
RealView Logic Tiles or the custom implementations of the CLCD interface.
