Only 1 pin can source 20mA and two pins can sink 20mA. This is like the freescale chips (Very poor peripheral performance). Funny N.

ARM's 20 pins JTAG for programming seems too much for a MCU. The PIC's 5 pin ICSP is nice. Which one is the better compare with PICs on price/performance? Funny N.

The lower end Cortex M3 compete well with high end 8-bit MCUs. Now the Cortex M0 parts seem to beat PIC18 handsomely with price and features. Even the price at qty of 1 is really low compared to PIC18F. http://www.mouser.com/Semiconductors/Microcontrollers-Microprocessors/Microcontrollers-MCU/_/N-6hpeg?Keyword=lpc11&FS=True&Ns=Pricing%7C0 http://www.mouser.com/Semiconductors/Microcontrollers-Microprocessors/Microcontrollers-MCU/_/N-6hpeg?Keyword=pic18F&FS=True&Ns=Pricing%7C0 -- 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 -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
