Paul,
Thanks, but your document brings me back to my original questions regarding powering this device.
On page four of that specs document, the schematic showing the interface between the LCD device and the MPU has the power and ground lines of both devices tied together. The 6809 is a five volt device so is that page wrong or am I allowed to power the device with 5 volts as indicated on page ten of the RA8835 controller manual linked on page five of the manual you linked?
If that page is wrong and the LCD device requires a separate 3.3 volt supply then do the address line, data lines, read/write line, etc. also need to be shifted to 3.3 volts from 5 volts?
Thanks again.
