Processor info of ConnectPort X4

Am I right to state that the 32MB refer to the RAM?

What about the processor info? The specs of ConnectPort X2e stated that the processor in their device is i.MX28 whereas the specs of ConnectPort X4 do not stated the processor info.

Can someone please advise?

correct.

X4 has an NS9360 (ARM9) processor. 150MHz, 32-bit. 32MB RAM and 16MB of flash storage.
