Is there such CPU that has SDRAM controller, USB host/slave, Ethernet
MAC, CAN as well as utility ADC and several PWM channels all in one
chip? The performance is not very critical; lower cost is important.
There are plenty of choices that have either (Ethernet + USB) or (ADC +
PWM), but it looks like none of them have both.

It's the SDRAM that really pushes this into a corner.
- rather mutually exclusive with 'lower cost' ? ;)

Choices would be (maybe) NXP Arm9, Freescale various, or infineon
higher end ?

and idle google for Cortex M3 SDRAM Controller pops up some new
emerging choices ?

["TI’s new LM3S1000 Series additions augment the series with a
versatile External Peripheral Interface (with modes to support SDRAM,
SRAM/Flash, Host-Bus, and M2M),"]

& Fujitsu ?

How about the TI/Luminary LM3S9B96?

Appears to have only a single USB controller, but I think it
covers the rest of your list. Not sure how good the SDRAM
controller is; I think this is the first line from Luminary
to support SDRAM. They have a pretty fine-grained feature
table, so there may be several devices in the line that can
work for you.

I think he is only asking for a single USB port, he just wants to be
able to use it as either a host or a slave. This part can do host,
slave or OTG! I am impressed with this part... especially at $9 for
1k qty. But... a 1200 page manual??? Wow! I guess that's why they
call it a system on chip!
