From: Vladimir Vassilevsky on 13 Jan 2010 16:26 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.

How about the TI/Luminary LM3S9B96? http://www.luminarymicro.com/products/lm3s9b96.html 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. -- 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 |
