Detailed Description
R
have the IIC pull-up resistors present on the expansion card. Bidirectional level shifting
transistors allow the expansion card to utilize 2.5V to 5V signaling on the IIC bus.
Power supply connections to the expansion connectors provide ground, 2.5V, 3.3V, and 5V
power pins. If the expansion card draws significant power from the ML50x board, ensure
that the total power draw can be supplied by the board.
The ML50x expansion connector is backward compatible with the expansion connectors
on the ML40x, ML32x, and ML42x boards, thereby allowing their daughter cards to be
used with the ML50x Evaluation Platform. Table 1-11 summarizes the additional
expansion I/O connections.
