Notes to Table 10–4:
(1) This information is preliminary.
(2) Use these timing parameters when you have not enabled the decompression and design security features.
(3) You can obtain this value if you do not delay the configuration by extending the nCONFIG or nSTATUS low pulse width.
(4) This value is applicable if you do not delay the configuration by externally holding nSTATUS low.
(5) The minimum and maximum numbers apply only if you chose the internal oscillator as the clock source for starting the device.
(6) Adding up t_CH and t_CL equals to t_CLK. When EP4SE230 t_CH is 3.6 ns (min), t_CL must be 4.4 ns and vice versa.
(7) Applicable to EP4SE230, EP4SE360, EP4SGX70, EP4SGX110, EP4SGX180, EP4SGX230, EP4SGX290 (except F45 package), EP4SGX360 (except
F45 package), EP4S40G2, EP4S100G2 devices.
(8) Applicable to EP4SE530, EP4SGX290 (only for F45 package), EP4SGX360 (only for F45 package), EP4SGX530, EP4S40G5, EP4S100G3,
EP4S100G4, EP4S100G5 devices.
(9) Applicable to EP4SE820 only.
