Table A-1 Voltage and Current Requirements
NOTE: The maximum current values for the +5V and 3.3V rails will not normally be
reached simultaneously. In general, the +5V rail current will increase with CPU activity,
and the 3.3V current with DRAM activity however caused, e.g. DMA transfers.
NOTE: This is for a board with 1 Gbyte DDR2 memory and with no Mass Storage Kit,
PMC modules or CompactFlash fitted.
NOTE: +/- 12V supplies are provided primarily for the PMC interface but the +12V supply
must be present for the board to operate correctly. When used for PMC they are limited
to 500mA for +12V and 200mA for -12V.
