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.

["TI=92s 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 ? -jg

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. -- newell N5TNL

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! Rick

I guess that's why they > call it a system on chip!I used a LM3S8962 (or something like that) in a project last summer. Loved it. Especially the way the pins are set to be either I/O or a single peripheral function; too many times I've been unable to use all the features of a CPU because a single pin would be shared among multiple peripherals. -- newell N5TNL
