I just get a chance to play with TI TMS470 ARM7 MCUs since I have access to an TMS470 Kickstart Development Kit now. http://focus.ti.com/docs/toolsw/folders/print/tms-fet470a256.html . Other than the fact that the I/Os are not 5V tolerant and potential high current consumption (still better than dsPICs), I think they are nice parts and the price is also quite okay, especially among those with CAN controllers. It seems that they are not as popular as Philip and Atmel ARM7 MCUs. Maybe some people in this list have used various ARM7 MCUs. Could you comments on these ARM7 chips? A good overview of the availabe ARM7 MCUs is here: http://www.gnuarm.com/ArmDevices_frame.html Regards, Xiaofan -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
