TABLE 1-2: PIC18F1220/1320 PINOUT I/O DESCRIPTIONS Pin Name Pin Number Pin Type Buffer Type Description PDIP/ SOIC SSOP QFN MCLR/VPP/RA5 MCLR VPP RA5 44 1 I P I ST — ST Master Clear (input) or programming voltage (input). Master Clear (Reset) input. This pin is an active-low Reset to the device. Programming voltage input. Digital input. OSC1/CLKI/RA7 OSC1 CLKI RA7 16 18 21 I I I/O ST CMOS ST Oscillator crystal or external clock input. Oscillator crystal input or external clock source input. ST buffer when configured in RC mode, CMOS otherwise. External clock source input. Always associated with pin function OSC1. (See related OSC1/CLKI, OSC2/CLKO pins.) General purpose I/O pin. OSC2/CLKO/RA6 OSC2 CLKO RA6 15 17 20 O O I/O — — ST Oscillator crystal or clock output. Oscillator crystal output. Connects to crystal or resonator in Crystal Oscillator mode. In RC, EC and INTRC modes, OSC2 pin outputs CLKO, which has 1/4 the frequency of OSC1 and denotes instruction cycle rate. General purpose I/O pin. PORTA is a bidirectional I/O port. RA0/AN0 RA0 AN0 11 26 I/O I ST Analog Digital I/O. Analog input 0. RA1/AN1/LVDIN RA1 AN1 LVDIN 22 27 I/O I I ST Analog Analog Digital I/O. Analog input 1. Low-Voltage Detect input. RA2/AN2/VREF- RA2 AN2 VREF- 67 7 I/O I I ST Analog Analog Digital I/O. Analog input 2. A/D reference voltage (low) input. RA3/AN3/VREF+ RA3 AN3 VREF+ 78 8 I/O I I ST Analog Analog Digital I/O. Analog input 3. A/D reference voltage (high) input. RA4/T0CKI RA4 T0CKI 33 28 I/O I ST/OD ST Digital I/O. Open-drain when configured as output. Timer0 external clock input. RA5 See the MCLR/VPP/RA5 pin. RA6 See the OSC2/CLKO/RA6 pin. RA7 See the OSC1/CLKI/RA7 pin. Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output ST = Schmitt Trigger input with CMOS levels I = Input O= Output P = Power OD = Open-drain (no P diode to VDD) |
