DS40001684E-page 9 PIC16F570 TABLE 3-2: PIC16F570 PINOUT DESCRIPTION Name Function Input Type Output Type Description VPP/MCLR VPP HV — Test mode high-voltage pin MCLR ST — Master Clear (Reset). This pin is an active-low Reset to the device. Voltage on MCLR/VPP must not exceed VDD during normal device operation or the device will enter Programming mode. Weak pull-up is always on. RA0/AN0 RA0 TTL CMOS Bidirectional I/O pin AN0 AN — ADC channel input RA1/AN1/C1IN+ RA1 TTL CMOS Bidirectional I/O pin AN1 AN — ADC channel input C1IN+ AN — Comparator 1 non-inverting input RA2/AN2/CVREF1 RA2 TTL CMOS Bidirectional I/O port AN2 AN — ADC channel input CVREF1 — AN Programmable Voltage Reference output 1 RA3/AN3/C2IN+ RA3 TTL CMOS Bidirectional I/O pin AN3 AN — ADC channel input C2IN+ AN — Comparator 2 non-inverting input RA4/AN4/T0CKI RA4 TTL CMOS Bidirectional I/O pin AN4 AN — ADC channel input T0CKI ST — Timer0 Schmitt Trigger input pin RA5/AN5 RA5 TTL CMOS Bidirectional I/O port AN5 AN — ADC channel input RA7/CLKIN/OSC1 RA7 TTL CMOS Bidirectional I/O port CLKIN ST — EXTRC Schmitt Trigger input OSC1 XTAL — XTAL oscillator input pin RA6/CLKOUT/OSC2 RA6 TTL CMOS Bidirectional I/O port CLKOUT — CMOS EXTRC/INTRC CLKOUT pin (FOSC/4) OSC2 — XTAL Oscillator crystal output. Connections to crystal or resonator in Crystal Oscillator mode (XT, HS and LP modes only, PORTB in other modes). RC0 RC0 ST CMOS Bidirectional I/O port RC1/AN6/OP1 RC1 ST CMOS Bidirectional I/O port AN6 AN — ADC channel input OP1 — AN Op amp 1 output RC2/OP1- RC2 ST CMOS Bidirectional I/O port OP1- AN — Op amp 1 inverting input RC3/OP1+ RC3 ST CMOS Bidirectional I/O port OP1+ AN — Op amp 1 non-inverting input RC4/OP2+ RC4 ST CMOS Bidirectional I/O port OP2+ AN — Op amp 2 non-inverting input RC5/OP2- RC5 ST CMOS Bidirectional I/O port OP2- AN — Op amp 2 inverting input RC6/AN7/OP2 RC6 ST CMOS Bidirectional I/O port AN7 AN — ADC channel input OP2 — AN Op amp 2 output Legend: I = Input, O = Output, I/O = Input/Output, P = Power, — = Not Used, TTL = TTL input, ST = Schmitt Trigger input, HV = High Voltage, AN = Analog Voltage |
