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.
It will be difficut to get a MicroController with the features that you are looking for.Firstly, if you are looking for a USB device, i thnk it should be with a USB device functionality & not a USB host functionality.There are a no. of ARM processors with this feature. Next about I2C, even if u dont have device with built in hardware for it, you can still incorporate the I2C functionality in S/W.So you can look at it as a not very important requirement.SPI interface is easily available. About TFT controller you wont get a processor with an on chip TFT controller. Lastly, what tools you are goin to use will determine what controller/processor or what make you will have to use.
