KEY CONNECTIONS
The key is designed to be plugged into a standard 5-pin,
0.1-inch center SIP receptacle (SAMTEC SS–105 or
equivalent). A guide is provided to prevent the key from
being plugged in backwards and aid in alignment of the
receptacle. For portable applications, contact to the key
pins can be determined to ensure connection integrity
before data transfer begins. CLK, RST, and DQ all have
internal 20K ohm pulldown resistors to ground that can
be sensed by a reading device.
