Hi,

I`m searching for a suitable microcontroller for my next application: the peripherial on the controller is a SPI touch controller, a encoder and some buttons as well as another spi device (led driver). All these datas should be transmit via usb to a personal computer.

I want to transmit these datas every 1ms to get a good response time for any user input (touch, encoder, buttons and so on); Moreover I`ll need 5 endpoints; usb should work with the interrupt transfer method; each event (touch event etc.) will be generate less than 64byte.

I hope there`s one ARM7 or cortex-m3 controller which is able to perform these instructions in time...

best regards
