Just started working on an LPC1111 design. Done some STM32 and NXP ARM7 st= uff in the past. Chose the '1111 because of low cost and 6 PWM outputs. A= s somebody else mentioned, the 32-bit timers make life quite a bit easier. = Even ST's 16-bit timers with 16-bit prescalers are far nicer than AVR time= rs. I'm a fan of Rowley Crossworks and especially their tasking library. Certa= inly as good as or better than AVR Studio (but I admit I haven't looked at = Studio 6). I'll still use an AVR if I need e.g. the high drive current or 5V operation= , but at this point I look at low-end 32-bit parts first, and only look at = 8-bit if I can't find a good match.
32-bit RISC now cheaper than 8-bit

AVR still has the lowest cost of entry for USB: less than $2 for Hard USB (At90usb*2) and $1 for Soft USB (Atmega*8). Most ARMs with USB have everything else tag along, for higher cost. If someone comes out with Soft USB for ARM M0/M3, we would gladly license it. For now, the death of AVR is pre-mature.
