Serial Configuration (EPCS) Devices Datasheet

Figure 3 shows the configuration of an FPGA device in the AS configuration scheme
with an EPCS device using the APU or a third-party programmer.
In an AS configuration, the FPGA acts as the configuration master in the
configuration flow and provides the clock to the EPCS device. The FPGA enables the
EPCS device by pulling the nCS signal low using the nCSO signal as shown in Figure 2
and Figure 3. Then, the FPGA sends the instructions and addresses to the EPCS device
using the ASDO signal. The EPCS device responds to the instructions by sending the
configuration data to the FPGA’s DATA0 pin on the falling edge of DCLK. The data is
latched into the FPGA on the next DCLK signal’s falling edge.
1 Before the FPGA enters configuration mode, ensure that VCC of the EPCS device is
ready. If VCC is not ready, you must hold nCONFIG low until all power rails of EPCS
device are ready.
The FPGA controls the nSTATUS and CONF_DONE pins during configuration in the AS
mode. If the CONF_DONE signal does not go high at the end of configuration, or if the
signal goes high too early, the FPGA pulses its nSTATUS pin low to start a
reconfiguration. If the configuration is successful, the FPGA releases the CONF_DONE
pin, allowing the external 10-k resistor to pull the CONF_DONE signal high. The FPGA
initialization begins after the CONF_DONE pin goes high. After the initialization, the
FPGA enters user mode.
f For more information about configuring the FPGAs in AS configuration mode or
other configuration modes, refer to the configuration chapter in the appropriate
device handbook.

Notes to Figure 3:
(1) For more information about the VCC value, refer to the configuration chapter in the appropriate device handbook.
(2) EPCS devices cannot be cascaded.
(3) Connect the MSEL[] input pins to select the AS configuration mode. For more information, refer to the configuration chapter in the appropriate
device handbook.
(4) For more information about configuration pin I/O requirements in an AS configuration scheme for an Altera FPGA, refer to the configuration
chapter in the appropriate device handbook.
