For details you have to go to the Microchip website. http://www.microchip.com/16bit dsPIC30 -- old CMOS technology, 5V, high current consumption (30MIPS) dsPIC33 -- 3.3V, lower current consumption, faster than dsPIC33 (40MIPS) PIC24F -- lower speed, more choices (16MIPS) PIC24H -- faster (40MIPS) They have a more modern core than PIC18. dsPICs have DSP instructions. The C30 compiler is based on gcc. -- Xiaofan http://mcuee.blogspot.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
