Notes to
(1) Connect these pull-up resistors to the V
CCIO
supply of the bank in which the pin resides.
(2) Power up the V
CC
of the EthernetBlaster, ByteBlaster II, or USB-Blaster cable with the 3.3-V supply.
(3) Pin 6 of the header is a V
IO
reference voltage for the MasterBlaster output driver.The V
IO
must match the V
device. For this value, refer to the
MasterBlaster Serial/USB Communications Cable User Guide
. When using the
ByteBlasterMV download cable, this pin is a no connect. When using the USB-Blaster and ByteBlaster II cables, this
pin is connected to
nCE
when it is used for AS programming, otherwise it is a no connect.
(4) The
MSEL
pin settings vary for different configuration voltage standards and POR time. To connect
MSEL
for AS
configuration schemes, refer to
, and
. Connect
the
MSEL
pins directly to V
CCA
or GND.
(5) Power up the V
CC
of the EthernetBlaster, ByteBlaster II, USB-Blaster, or ByteBlasterMV cable with a 2.5-V V
CCA
supply.
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
.
(6) You must place the diodes and capacitors as close as possible to the Cyclone IV device. Altera recommends using
the Schottky diode, which has a relatively lower forward diode voltage (VF) than the switching and Zener diodes, for
effective voltage clamping.
(7) These pins are dual-purpose I/O pins. The
nCSO
pin functions as
FLASH_nCE
pin in AP mode. The
ASDO
pin functions
as
DATA[1]
pin in AP and FPP modes.
(8) Resistor value can vary from 1 k
to 10 k
..
(9) Only Cyclone IV GX devices have an option to select
CLKUSR
(40 MHz maximum) as the external clock source for
DCLK
.
