HSMC Expansion Connector
HSMC Expansion Connector
The HSMC interface provides a mechanism to extend the peripheral set of an FPGA host board by
means of a mezzanine card, which can address today’s high speed signaling requirement as well as
standard or legacy low-speed device interface support.
Table 3-1 lists the pin assignments of the
HSMC connector.
