Power
The 16-layer development board has 10 signal layers and 6 ground/VCC
planes. The board is powered from a single, well regulated 16-V supply.
Regulators on the board are used to develop the V_CCINT (1.2 V), V_CCIO
(3.3 V), and V_CC5 (5.0 V) voltages. The board includes a Power-on LED
that indicates the presence of V_CCIO.
The following board elements are powered by the 3.3 V supply:
■ LEDs
■ Switches
■ Crystal oscillator
