UNIVERSAL (3.3V AND 5V) PCI BUS OCTAL UART

1.0 APPLICATION EXAMPLES
The XR17D158 is designed to operate with VCC (voltage to the UART Core Logic) at 5V only, irrespective of
whether the PCI bus is at 3.3V or 5V. Table 1 below shows the valid combinations of VCC and the PCI Bus
Voltage, VIO that can be used for the device..
A typical application for a universal add-in card (VCC must be 5V) is shown in Figure 3. In an embedded
system, the designer must still choose 5V power supply for the VCC regardless of VIO (3.3 or 5V). In
Figure 4, examples 1 and 2 show valid applications of the XR17D158 in an embedded system.
