Description
PIC18F6X20 PIC18F8X20
Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output
ST = Schmitt Trigger input with CMOS levels Analog = Analog input
I = Input O = Output
P = Power OD = Open-Drain (no P diode to V
DD)
Note 1: Alternate assignment for CCP2 when CCP2MX is not selected (all operating modes except
Microcontroller).
2: Default assignment when CCP2MX is set.
3: External memory interface functions are only available on PIC18F8X20 devices.
4: CCP2 is multiplexed with this pin by default when configured in Microcontroller mode. Otherwise, it is
multiplexed with either RB3 or RC1.
5: PORTH and PORTJ are only available on PIC18F8X20 (80-pin) devices.
6: AV
DD must be connected to a positive supply and AVSS must be connected to a ground reference for
proper operation of the part in user or ICSP modes. See parameter D001A for details.
