TABLE 1-3: PIC16F639 PINOUT DESCRIPTIONS Name Function Input Type Output Type Description VDD VDD D — Power supply for microcontroller RA5/T1CKI/OSC1/CLKIN RA5 TTL CMOS General purpose I/O. Individually controlled interrupt-on-change. Individually enabled pull-up/pull-down. T1CKI ST — Timer1 clock OSC1 XTAL — XTAL connection CLKIN ST — TOSC/4 reference clock RA4/T1G/OSC2/CLKOUT RA4 TTL CMOS General purpose I/O. Individually controlled interrupt-on-change. Individually enabled pull-up/pull-down. T1G ST — Timer1 gate OSC2 — XTAL XTAL connection CLKOUT — CMOS TOSC reference clock RA3/MCLR/VPP RA3 TTL — General purpose input. Individually controlled interrupt-on-change. MCLR ST — Master Clear Reset. Pull-up enabled when configured as MCLR. VPP HV — Programming voltage RC5 RC5 TTL CMOS General purpose I/O RC4/C2OUT RC4 TTL CMOS General purpose I/O C2OUT — CMOS Comparator2 output RC3/LFDATA/RSSI/CCLK/SDIO RC3 TTL CMOS General purpose I/O LFDATA — CMOS Digital output representation of analog input signal to LC pins. RSSI — Current Received signal strength indicator. Analog current that is proportional to input amplitude. CCLK — — Carrier clock output SDIO TTL CMOS Input/Output for SPI communication VDDT VDDT D — Power supply for Analog Front-End. In this document, VDDT is treated the same as VDD, unless otherwise stated. LCZ LCZ AN — 125 kHz analog Z channel input LCY LCY AN — 125 kHz analog Y channel input LCX LCX AN — 125 kHz analog X channel input LCCOM LCCOM AN — Common reference for analog inputs VSST VSST D — Ground reference for Analog Front-End. In this document, VSST is treated the same as VSS, unless otherwise stated. RC2/SCLK/ALERT RC2 TTL CMOS General purpose I/O SCLK TTL — Digital clock input for SPI communication ALERT —OD Output with internal pull-up resistor for AFE error signal RC1/C2IN-/CS RC1 TTL CMOS General purpose I/O C2IN- AN — Comparator1 input - negative CS TTL — Chip select input for SPI communication with internal pull-up resistor RC0/C2IN+ RC0 TTL CMOS General purpose I/O C2IN+ AN — Comparator1 input - positive RA2/T0CKI/INT/C1OUT RA2 ST CMOS General purpose I/O. Individually controlled interrupt-on-change. Individually enabled pull-up/pull-down. T0CKI ST — External clock for Timer0 INT ST — External Interrupt C1OUT — CMOS Comparator1 output RA1/C1IN-/VREF/ICSPCLK RA1 TTL CMOS General purpose I/O. Individually controlled interrupt-on-change. Individually enabled pull-up/pull-down. C1IN- AN — Comparator1 input – negative ICSPCLK ST — Serial Programming Clock RA0/C1IN+/ICSPDAT/ULPWU RA0 TTL — General purpose I/O. Individually controlled interrupt-on-change. Individually enabled pull-up/pull-down. Selectable Ultra Low-Power Wake-up pin. C1IN+ AN — Comparator1 input – positive ICSPDAT TTL CMOS Serial Programming Data IO ULPWU AN — Ultra Low-Power Wake-up input VSS VSS D — Ground reference for microcontroller Legend: AN = Analog input or output CMOS = CMOS compatible input or output D = Direct HV = High Voltage ST = Schmitt Trigger input with CMOS levels OD = Direct TTL = TTL compatible input XTAL = Crystal |
