Notes to Table 1–4:
(1) All VCCA pins must be powered to 2.5 V (even when PLLs are not used) and must be powered up and powered down at the same time.
(2) You must connect VCCD_PLL to VCCINT through a decoupling capacitor and ferrite bead.
(3) Power supplies must rise monotonically.
(4) VCCIO for all I/O banks must be powered up during device operation. Configurations pins are powered up by VCCIO of I/O Banks 3, 8, and 9 where
I/O Banks 3 and 9 only support VCCIO of 1.5, 1.8, 2.5, 3.0, and 3.3 V. For fast passive parallel (FPP) configuration mode, the VCCIO level of I/O
Bank 8 must be powered up to 1.5, 1.8, 2.5, 3.0, and 3.3 V.
(5) You must set VCC_CLKIN to 2.5 V if you use CLKIN as a high-speed serial interface (HSSI) refclk or as a DIFFCLK input.
(6) The CLKIN pins in I/O Banks 3B and 8B can support single-ended I/O standard when the pins are used to clock left PLLs in non-transceiver
applications.
(7) The POR time for Standard POR ranges between 50 and 200 ms. VCCINT, VCCA, and VCCIO of I/O Banks 3, 8, and 9 must reach the recommended
operating range within 50 ms.
(8) The POR time for Fast POR ranges between 3 and 9 ms. VCCINT, VCCA, and VCCIO of I/O Banks 3, 8, and 9 must reach the recommended operating
range within 3 ms.
ESD Performance
This section lists the electrostatic discharge (ESD) voltages using the human body
model (HBM) and charged device model (CDM) for Cyclone IV devices general
purpose I/Os (GPIOs) and high-speed serial interface (HSSI) I/Os. Table 1–5 lists the
ESD for Cyclone IV devices GPIOs and HSSI I/Os.

Notes to Table 1–5:
