PMC Connector

(JH1 & JH2)

The PCI mezzanine card (PMC) connector, formed by JH1 and JH2,

allows Nios II systems in the FPGA to interface to daughter cards using

the standard 32-bit PMC form factor. Refer to Figure 2–11. The PMC

connector is capable of 33MHz and 66 MHz, and is configured as the PMC

host.

w Before connecting a daughter card to the PMC connector, the

FPGA must first be configured with a design that includes a

PMC interface. Damage to either the FPGA or daughter card can

result if the FPGA is not configured correctly.

The factory-programmed Nios II reference design does not include a

PMC interface.

Notes to Ta b le 2 – 13 :

(1) Nets proto_io16, proto_io20, and proto_io21 do not connect to CON3.

(2) The FPGA I/O pin controls a power MOSFET that supplies 5V VCC to this net.

(3) proto1_RESET_n is driven by the EPM7256AE configuration controller device

(U3).
