Table 8–10. PS Configuration Timing Parameters For Cyclone IV Devices (Part 2 of 2)
Cyclone IV Device Handbook, Volume 1
Notes to
(1) This information is preliminary.
(2) Applicable for Cyclone IV GX and Cyclone IV E devices with 1.2-V core voltage.
(3) Applicable for Cyclone IV E devices with 1.0-V core voltage.
(4) This value is applicable if you do not delay configuration by extending the nCONFIG or nSTATUS low pulse width.
(5) This value is applicable if you do not delay configuration by externally holding the nSTATUS low.
(6) The minimum and maximum numbers apply only if you choose the internal oscillator as the clock source for starting the device.
(7) Cyclone IV E devices with 1.0-V core voltage have slower F

PS Configuration Using a Download Cable
In this section, the generic term “download cable” includes the Altera USB-Blaster
USB port download cable, MasterBlaster™ serial and USB communications cable,
ByteBlaster II parallel port download cable, the ByteBlasterMV
download cable, and the EthernetBlaster communications cable.
In the PS configuration with a download cable, an intelligent host (such as a PC)
transfers data from a storage device to the Cyclone IV device through the download
cable.
