The recommended operating temperature range for the PCI2040PGE is -40°C to 85°C.
The PCI2040PGE can be configured for 3.3V or 5V operation by connecting the VCC pin to the desired voltage supply. Additionally, the I/O voltage (VIO) pin should be connected to the same voltage supply as the VCC pin.
The maximum clock frequency supported by the PCI2040PGE is 66 MHz.
A reset circuit can be implemented using a resistor and capacitor connected to the RESET# pin. The recommended values are a 1 kΩ resistor and a 0.1 μF capacitor.
The PERST# pin is an active-low reset input that resets the PCI interface. It is typically connected to a power-on reset circuit or a manual reset switch.
