Notes to
(1) Connect these pull-up resistors to the V
(2) The nCEO pin is left unconnected or used as a user I/O pin when it does not feed the nCE pin of another device.
(3) Power up the V
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect the MSEL pins, refer to
(5) The diodes and capacitors must be placed as close as possible to the Cyclone IV device. You must ensure that the diodes and capacitors maintain
(6) When cascading Cyclone IV devices in a multi-device AS configuration, connect the repeater buffers between the master and slave devices for
(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
(8) Only Cyclone IV GX devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for DCLK.

a maximum AC voltage of 4.1 V. The external diodes and capacitors are required to prevent damage to the Cyclone IV device AS configuration
input pins due to possible overshoot when programming the serial configuration device with a download cable. 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.
DATA[0] and DCLK. All I/O inputs must maintain a maximum AC voltage of 4.1 V. The output resistance of the repeater buffers must fit the
maximum overshoot equation outlined in
and FPP modes.
