3.14.1
Core and I/O Voltage Supply Connections
The OMAP5910 device is extremely flexible regarding the implementation of the core and I/O voltage supplies
of the device.
In a typical system, all of the core voltage supplies (CV
DDx
) may be connected together and powered from
one common supply. Likewise, all of the I/O voltage supplies (DV
DDx
) may be connected together and
powered from a common supply. Figure 34 illustrates this common system configuration.

Figure 34. Supply Connections for a Typical System
Several of the I/O voltage supplies (DV
DD3
, DV
DD4
and DV
DD5
) are capable of operating at lower voltages
(1.8 V nominal) while the other I/O supplies run at 3.3 V nominal. This is advantageous for systems which
mix standard 3.3-V devices with low voltage memory devices or other low voltage logic. Refer to Table 22
to determine which I/O pins are powered by each of the DV
DDx
supplies. Figure 35 illustrates an example
of this type of mixed voltage system configuration.
