TABLE 1-3: PIC16F874A/877A PINOUT DESCRIPTION Pin Name PDIP Pin# PLCC Pin# TQFP Pin# QFN Pin# I/O/P Type Buffer Type Description OSC1/CLKI OSC1 CLKI 13 14 30 32 I I ST/CMOS(4) Oscillator crystal or external clock input. Oscillator crystal input or external clock source input. ST buffer when configured in RC mode; otherwise CMOS. External clock source input. Always associated with pin function OSC1 (see OSC1/CLKI, OSC2/CLKO pins). OSC2/CLKO OSC2 CLKO 14 15 31 33 O O — Oscillator crystal or clock output. Oscillator crystal output. Connects to crystal or resonator in Crystal Oscillator mode. In RC mode, OSC2 pin outputs CLKO, which has 1/4 the frequency of OSC1 and denotes the instruction cycle rate. MCLR/VPP MCLR VPP 1 2 18 18 I P ST Master Clear (input) or programming voltage (output). Master Clear (Reset) input. This pin is an active low Reset to the device. Programming voltage input. PORTA is a bidirectional I/O port. RA0/AN0 RA0 AN0 2 3 19 19 I/O I TTL Digital I/O. Analog input 0. RA1/AN1 RA1 AN1 3 4 20 20 I/O I TTL Digital I/O. Analog input 1. RA2/AN2/VREF-/CVREF RA2 AN2 VREF- CVREF 4 5 21 21 I/O I I O TTL Digital I/O. Analog input 2. A/D reference voltage (Low) input. Comparator VREF output. RA3/AN3/VREF+ RA3 AN3 VREF+ 5 6 22 22 I/O I I TTL Digital I/O. Analog input 3. A/D reference voltage (High) input. RA4/T0CKI/C1OUT RA4 T0CKI C1OUT 6 7 23 23 I/O I O ST Digital I/O – Open-drain when configured as output. Timer0 external clock input. Comparator 1 output. RA5/AN4/SS/C2OUT RA5 AN4 SS C2OUT 7 8 24 24 I/O I I O TTL Digital I/O. Analog input 4. SPI slave select input. Comparator 2 output. Legend: I = input O = output I/O = input/output P = power — = Not used TTL = TTL input ST = Schmitt Trigger input Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt. 2: This buffer is a Schmitt Trigger input when used in Serial Programming mode. 3: This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise. |
