Dear sir, please help me out in selecting arm based 32 bit microcontroller which supports buit-in following features. - SPI/I2C - USB 2.0 - Ethernet - TFT Display controller - should be low cost - Approximate 256 KB internal RAM - Approximate 1MB internal Flash - also please give information about development tool for that paricular controller Thanks in advance with regards sushma.k.s.
Link sent by you is not having option for ethernet support.<p> Did you even try using the search engine ? Wait, no, you didn't ! If you had cared to enter your RAM/ROM, SPI, I2C and USB requirements, you would have seen that there are exactly six matches, two of which have built-in ethernet. If this is too much work for you, how are you going to build the actual device ? And you're probably not going to find a uC with built-in TFT controller.
... there do not seem to be devices that have as much RAM and ROM as you require. For a microcontroller, 1 MB ROM and 256 kB RAM are huge amounts. What you are looking for sounds more like a System-on-a-Chip than a microcontroller. You will have to review your requirements and modify them or toss some of them out. First candidate for the latter would be the "low cost" requirement, since your requirements are pretty much "high end".
