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.
... 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".
