DS40001709C-page 7 PIC16F753/HV753 TABLE 1-1: PIC16F753/HV753 PINOUT DESCRIPTION Name Function Input Type Output Type Description RA0/AN0/C1IN0+/DACOUT/ FVROUT/ICSPDAT RA0 TTL HP General purpose I/O with IOC and WPU. AN0 AN — A/D Channel 0 input. C1IN0+ AN — Comparator C1 positive input. DACOUT — AN DAC unbuffered Voltage Reference output. FVROUT — AN DAC/FVR buffered Voltage Reference output. ICSPDAT ST HP Serial Programming Data I/O. RA1/AN1/C1IN0-/C2IN0-/ VREF+/FVRIN/ICSPCLK RA1 TTL CMOS General purpose I/O with IOC and WPU. AN1 AN — A/D Channel 1 input. C1IN0- AN — Comparator C1 negative input. C2IN0- AN — Comparator C2 negative input. VREF+ AN — A/D Positive Voltage Reference input. FVRIN AN — Voltage reference input. ICSPCLK ST — Serial Programming Clock. RA2/AN2/INT/C1OUT/ T0CKI/COG1FLT RA2 ST HP General purpose I/O with IOC and WPU. AN2 AN — A/D Channel 2 input. INT ST — External interrupt. C1OUT — HP Comparator C1 output. T0CKI ST — Timer0 clock input. COG1FLT ST — COG auto-shutdown fault input. RA3(1)/T1G(3)/VPP/MCLR(4) RA3 TTL — General purpose input with WPU. T1G ST — Timer1 Gate input. VPP HV — Programming voltage. MCLR ST — Master Clear w/internal pull-up. RA4/AN3/T1G(2)/CLKOUT RA4 TTL CMOS General purpose I/O with IOC and WPU. AN3 AN — A/D Channel 3 input. T1G ST — Timer1 Gate input. CLKOUT — CMOS FOSC/4 output. RA5/T1CKI/COG1OUT0(3)/ C2IN1-/CLKIN RA5 TTL CMOS General purpose I/O with IOC and WPU. T1CKI ST — Timer1 clock input. CLKIN ST — External Clock input (EC mode). RC0/AN4/OPA1IN+/C2IN0+ RC0 TTL CMOS General purpose I/O with IOC and WPU. AN4 AN — A/D Channel 4 input. OPA1IN+ AN — Op amp positive input. C2IN0+ AN — Comparator C2 positive input. RC1/AN5/OPA1IN-/C1IN1-/ C2IN1- RC1 TTL CMOS General purpose I/O with IOC and WPU. AN5 AN — A/D Channel 5 input. OPA1IN- AN — Op amp negative input. C1IN1- AN — Comparator C1 negative input. C2IN1- AN — Comparator C2 negative input. Legend: AN = Analog input or output CMOS = CMOS compatible input or output TTL = TTL compatible input ST = Schmitt Trigger input with CMOS levels HP = High Power HV = High Voltage * Alternate pin function. Note 1: Input only. 2: Default pin function via the APFCON register. 3: Alternate pin function via the APFCON register. 4: RA3 pull-up is enabled when pin is configured as MCLR in Configuration Word. |
