Figure 9–19 shows PS configuration for multi Cyclone III device family using a

MasterBlaster, USB-Blaster, ByteBlaster II, or ByteBlasterMV cable.

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.

Figure 9–19. Multi-Device PS Configuration Using a USB-Blaster, MasterBlaster, ByteBlaster II,

ByteBlasterMV, or Ethernet Blaster 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 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 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 nCE when 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 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 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.
