Description
PIC18F6X8X devices are available in 64-pin TQFP and 68-pin PLCC packages. PIC18F8X8X devices are available in the 80-pin TQFP package. They are differentiated from each other in four ways: 1. Flash program memory (48 Kbytes for PIC18FX585 devices, 64 Kbytes for PIC18FX680) 2. A/D channels (12 for PIC18F6X8X devices, 16 for PIC18F8X8X) 3. I/O ports (7 on PIC18F6X8X devices, 9 on PIC18F8X8X) 4. External program memory interface (present only on PIC18F8X8X devices) All other features for devices in the PIC18F6585/8585/6680/8680 family are identical.
