FPP Configuration Timing when DCLK-to-DATA[] = 1

Note: When you enable decompression or the design security feature, the DCLK-to-DATA[] ratio varies for FPP ×8, FPP ×16, and FPP ×32. For the respective DCLK-to-DATA[] ratio, refer to the DCLK-to-DATA[] Ratio for Intel® Cyclone® 10 GX Devices table.
Table 48.  FPP Timing Parameters When the DCLK-to-DATA[] Ratio is 1 for Intel® Cyclone® 10 GX DevicesUse these timing parameters when the decompression and design security features are disabled.
Symbol Parameter Minimum Maximum Unit
tCF2CD nCONFIG low to CONF_DONE low 1,440 ns
tCF2ST0 nCONFIG low to nSTATUS low 960 ns
tCFG nCONFIG low pulse width 2 μs
tSTATUS nSTATUS low pulse width 268 3,000 71 μs
tCF2ST1 nCONFIG high to nSTATUS high 3,000 72 μs
tCF2CK 73 nCONFIG high to first rising edge on DCLK 3,010 μs
tST2CK 73 nSTATUS high to first rising edge of DCLK 10 μs
tDSU DATA[] setup time before rising edge on DCLK 5.5 ns
tDH DATA[] hold time after rising edge on DCLK 0 ns
tCH DCLK high time 0.45 × 1/fMAX s
tCL DCLK low time 0.45 × 1/fMAX s
tCLK DCLK period 1/fMAX s
fMAX DCLK frequency (FPP ×8/×16/×32) 100 MHz
tCD2UM CONF_DONE high to user mode   74 175 830 μs
tCD2CU CONF_DONE high to CLKUSR enabled 4 × maximum DCLK period
tCD2UMC CONF_DONE high to user mode with CLKUSR option on tCD2CU +
(600 × CLKUSR period)
71 This value is applicable if you do not delay configuration by extending the nCONFIG or nSTATUS low pulse width.
72 This value is applicable if you do not delay configuration by externally holding the nSTATUS low.
73 If nSTATUS is monitored, follow the tST2CK specification. If nSTATUS is not monitored, follow the tCF2CK specification.
74 The minimum and maximum numbers apply only if you chose the internal oscillator as the clock source for initializing the device.
