SPC5777C VDDE2 and VDDE2A

[liuxingqiao]

Hello,

   Could anyone tell me what is the relationship between VDDE2 and VDDE2A supply pins of SPC5777C? Could they be tied to different voltages, for example, VDDE2 tied to 5V and VDDE2A tied to 3.3V?

   Thanks in advance.

   Best regares,

There is none. In the device predecessor (MPC5676R) it was one domain. On the MPC5777C it has been split onto 2 domains (in order to minimize I/O pins affected when using Ethernet).

Yes, they can be tied to different voltages, as you shown in the example.
