Wow. Out of curiosity, how little power do you have? Last night I programmed a 3 digit LCD counter using a 16f877 and found that without using any low power modes it only consumes 23uA at 3V. That'll run for over a year on a CR2032 with the LCD on full time. I've used the MSP430 devices and they are also low power, but at the time I didn't optimize power usage since the rest of the circuit (accelerometer, mainly) required 1mA, so there wasn't much to gain. The main problem with them is they are expensive. The main advantage is the nice LCD controller, 16 bit data path, and multiplier. -Adam -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
