HSMC Connector (J1)
The THDB-SUM board contains an Altera standard HSMC connector (J1) to connect
to Altera FPGA starter or development board. All the other connector interfaces on
the THDB-SUM board are connected to the HSMC connector.
Figure 2–3 , Figure 2–4 , and Figure 2–5 show the pin-outs of the HSMC connector for
banks 1, 2, and 3, respectively.
JP4 SC connector logic level configuration
header When open, selects 3.3 V for Santa Cruz header I/O voltage.
When closed, selects 5.0 V.
U1–U2 Bus switches Multiplexer to switch between USB or Santa Cruz I/O based
on setting of JP2.
U3–U8 Level shifters Provides I/O level shifting based on jumper settings of JP3
and JP4.
U10 I 2 C serial EEPROM Uses one 2-Kbit EEPROM.
U11 USB On-The-Go transceiver Provide USB interface to the HSMC interface host board.
