Hello,
I am familiar with the PIC16F88 and have been using at at 5 volts for a while. I am working on a new application that runs off of around 3 volts. From reading the data sheet I realized that I need to get the 16LF88 in order to run it at 3 volts. I am now using the LF88 and I still cannot get it to run at 3 volts. It does not work until I give it around four volts.
My guess is that my oscillator is configured incorrectly to work off of this low voltage. I am currently running it off of the int_rc at 8 MHz.
osccon = 01110000b;
Right now my best guess is that I need to re-program it to run at 4 MHz, but thought I would check with you guys before I waste my time when it may be something else. (It is currently SMD in circuit, and I don't have ICSP pins on the board)
Thanks!
