Like all Microchip PIC18 devices, members of the PIC18F2525/2620/4525/4620 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an "F" in the part number (such as PIC18F2620), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by "LF" (such as PIC18LF2620), function over an extended VDD range of 2.0V to 5.5V.
Have tested PIC18LF4525.
Have tested PIC18LF2620 at 3.3 volts. It comes in a 28 pin package which should have enough IO for us. Note that we have been using the PIC18F4525 40 pin IC for apsc1299 but this package style is needed in that case because it fits on the brainboard of our robots.
