Other Expansion I/O Connectors

In addition to the high speed I/O paths, additional I/O signals and power connections are 
available to support expansion cards plugged into SP305 board. The 14 I/O pins from the 
general purpose FPGA I/O are connected to expansion connector J3. This arrangement 
permits additional I/O’s to be connected to the expansion connector. 

The expansion connector also allows the board's JTAG chain to be extended onto the 
expansion card by setting jumper J26 accordingly.

The IIC bus on the board is also extended onto the expansion connector to allow additional 
IIC devices to be bused together. If the expansion IIC bus is to be utilized, the user must 
have the IIC pull-up resistors present on the expansion card. Bi-directional 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 SP-305 board, the user 
must ensure that the total power draw can be supplied by the board.

The SP-305 expansion connector is backward compatible with the expansion connectors on 
the ML320, ML321, and ML323 boards, thereby allowing their daughter cards to be used 
with the SP-305 Development Platform. 

Table 2-25

 summarizes the additional expansion 

I/O connections.
