COG 128x64 LCD Help |

I am wanting to use a COG 128x64 LCD, possibly the optrex F-51320GNF-AC which is available from Digi-Key.
The documentation is pretty vague on what is required to drive the LCD.
Powering LCD 3.3V or 5v? , Can I use 5 volt PIC to drive the data interface or do I have to do conversion for 3.3v.
Sample schematics are given with capactitors, with different power modes.
whats the best and easiest way to power it up.
I simply just want to hook it up to a PIC, apply power to the LCD send data and go from there.
Any help on this would be greatly appreciated.
Thanks.

The datasheet timing specs are given with Vdd=5.0V
So except for finding values for all the power supply capacitors (something is wrong with the PDF I downloaded, it seems to be missing 3 pages) I'd just hook up like figure 4.2 and use 5.0V for my Vdd of the display and the PIC. _________________ Rob Young
