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 1–4:

(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.

(3) Power supplies must rise monotonically.

Bank 8 must be powered up to 1.5, 1.8, 2.5, 3.0, and 3.3 V.

(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.
