If the PIC16F84 is to operate above 4 MHz, officially you need a -10 chip, and a power supply from 4.5 to 5.5 V. At 4 MHz or below, either a -10 or -04 chip will work, and the power supply range is extended to 4.0-6.0 V. The -10 chip is not recommended for the LP mode (below 200 KHz), but it will usually work there. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
