Figure 2. Development Kit Boards
(Evaluation socket daughter board combined with a USB mother board)
The socket daughter board for 5x2503, combined with a USB mother board, is used for the purpose of validation and measurement on all
outputs. After a configuration is validated on the USB mother board, the board can be connected along with the specific socket daughter
board for programming on blank parts of MicroClock family devices. Note that blank parts can only be burnt once through the socket
daughter board. The socket daughter board is bundled with a USB mother board. The following description and images are restricted to
the socket daughter board.
On the footprint of the socket daughter board, a pin orientation identifies the position of Pin 1 as shown in
Figure 3
. Align the dot of the
blank part in the socket as pointed. After placing the blank part, secure the socket cover.
