A.12. Tile header connectors

Figure A.19 shows the pin numbers and power-blade usage of the HDRX, HDRY, and HDRZ headers on the baseboard.

The pin numbering and supply voltages are the same for both tile sites.


The I/O voltage on some pins of Logic Tiles can be programmed by changing resistors on the tile. Signals between Logic Tiles can be altered safely if both the sending and receiving tile use the same voltage. (See Power supply.)

Table A.20, Table A.21, and Table A.22 list the signals on each header pin. See the ARM LT-XC2V4000+ RealView Logic Tile User Guide for details of the header signals present on the Logic Tile. See the Core Tile User Guide for details of the header signals present on the Core Tile.

Table A.19 lists the Samtec part numbers.

The baseboard uses QTH-xxx-05-F-D-A-K connectors on the top of the board.

Core Tiles and Logic Tiles use the corresponding QSH-xxx-01-F-D-A-D connectors on the bottom of the tiles.


Samtec describes the QTH connector, used on the baseboard, as a header and the QSH connector, used on the lower side of the tiles, as a socket.
