receiving the same configuration data. Configuration pins (nCONFIG, nSTATUS,
DCLK, DATA[7..0], and CONF_DONE) are connected to every device in the chain.
Configuration signals may require buffering to ensure signal integrity and prevent
clock skew problems. Ensure that the DCLK and DATA lines are buffered. Devices must
be of the same density and package. All devices start and complete configuration at
the same time.
Figure 8–21. Multi-Device FPP Configuration Using an External Host When Both Devices Receive the
Same Data
Notes to
(1) You must connect the pull-up resistor to a supply that provides an acceptable input signal for all devices in the chain.
(2) The nCEO pins of both devices are left unconnected or used as user I/O pins when configuring the same
(3) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect the MSEL pins,
(4) All I/O inputs must maintain a maximum AC voltage of 4.1 V. DATA[7..0] and DCLK must fit the maximum
You can use a single configuration chain to configure Cyclone IV devices with other
Altera devices that support FPP configuration. To ensure that all devices in the chain
complete configuration at the same time or that an error flagged by one device starts
reconfiguration in all devices, tie all the CONF_DONE and nSTATUS pins together.
For more information about configuring multiple Altera devices in the same
configuration chain, refer to
