NOTES:

  1. Estimate assumes no codec and Xilinx XC4020XLA.  Measurements are on a XC4013XL
  2. Reflects low standby power of XC4020XLA part.
  3. Rough number - ARM standby mode is not quite correct yet.
  4. Can’t program Xilinx if codec is enabled first.
  5. Unless otherwise indicated, Xilinx programmed means that the LEDs are blinking.
  6. LEDs draw about 5ma apiece.
