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 VCCA supply.
(2) You only need the pull-up resistors on DATA[0]and DCLKif the download cable is the only configuration scheme
used on your board. This is to ensure that DATA[0] and DCLKare 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 VIO reference voltage for the MasterBlaster output driver. VIO must match the VCCA 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 nCEwhen it is
used for AS programming. Otherwise, it is a no connect.
(4) Connect the pull-up resistor to the VCCIO supply voltage of the I/O bank in which the nCEpin resides.
(5) The nCEOpin 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 VCCA or GND.
(7) Power up the VCC of the ByteBlaster II, USB-Blaster, or ByteBlasterMV cable with a 2.5- V supply from VCCA
.
Third-party programmers must switch to 2.5 V. Pin 4 of the header is a VCC 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.
