TABLE 1-2: PIC18F6585/8585/6680/8680 PINOUT I/O DESCRIPTIONS (CONTINUED) Pin Name Pin Number Pin Type Buffer Type Description PIC18F6X8X PIC18F8X8X TQFP PLCC TQFP 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 VDD) Note 1: Alternate assignment for CCP2 in all operating modes except Microcontroller – applies to PIC18F8X8X only. 2: Default assignment when CCP2MX is set. 3: External memory interface functions are only available on PIC18F8X8X 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 PIC18F8X8X (80-pin) devices. 6: PSP is available in Microcontroller mode only. 7: On PIC18F8X8X devices, these pins can be multiplexed with RH7/RH6 by changing the ECCPMX configuration bit. |
