Configuration Features
Figure 9–19 shows PS configuration for multi Cyclone III device family using a
MasterBlaster, USB-Blaster, ByteBlaster II, or ByteBlasterMV cable.

Notes to Figure 9–19:
(1) The pull-up resistor must be connected to the same supply voltage as the V_CCA supply.
(2) You only need the pull-up resistors on DATA[0] and DCLK if the download cable is the only configuration scheme
used on your board. This is to ensure that DATA[0] and DCLK are not left floating after configuration. For example, if
you are also using a configuration device, you do not need the pull-up resistors on DATA[0] and DCLK.
(3) Pin 6 of the header is a V_IO reference voltage for the MasterBlaster output driver. V_IO must match the V_CCA of the
device. For this value, refer to the MasterBlaster Serial/USB Communications Cable User Guide. In ByteBlasterMV,
this pin is a no connect. In USB-Blaster, ByteBlaster II, and Ethernet Blaster, this pin is connected to nCE when it is
used for AS programming. Otherwise, it is a no connect.
(4) Connect the pull-up resistor to the V_CCIO supply voltage of the I/O bank in which the nCE pin resides.
(5) The nCEO pin of the last device in the chain is left unconnected or used as a user I/O pin.
(6) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL[3..0] for
PS configuration schemes, refer to Table 9–7 on page 9–11. Connect the MSEL pins directly to V_CCA or GND.
(7) Power up the V_CC of the ByteBlaster II, USB-Blaster, or ByteBlasterMV cable with a 2.5- V supply from V_CCA.
Third-party programmers must switch to 2.5 V. Pin 4 of the header is a V_CC power supply for the MasterBlaster cable.
The MasterBlaster cable can receive power from either 5.0- or 3.3-V circuit boards, DC power supply, or 5.0 V from
the USB cable. For this value, refer to the MasterBlaster Serial/USB Communications Cable User Guide.
FPP Configuration
The FPP configuration in Cyclone III device family is designed to meet the increasing
demand for faster configuration time. Cyclone III device family is designed with the
capability of receiving byte-wide configuration data per clock cycle.
