DS70286C-page 15 dsPIC33FJXXXGPX06/X08/X10 TABLE 1-1: PINOUT I/O DESCRIPTIONS Pin Name Pin Type Buffer Type Description AN0-AN31 I Analog Analog input channels. AVDD P P Positive supply for analog modules. This pin must be connected at all times. AVSS P P Ground reference for analog modules. CLKI CLKO I O ST/CMOS — External clock source input. Always associated with OSC1 pin function. Oscillator crystal output. Connects to crystal or resonator in Crystal Oscillator mode. Optionally functions as CLKO in RC and EC modes. Always associated with OSC2 pin function. CN0-CN23 I ST Input change notification inputs. Can be software programmed for internal weak pull-ups on all inputs. COFS CSCK CSDI CSDO I/O I/O I O ST ST ST — Data Converter Interface frame synchronization pin. Data Converter Interface serial clock input/output pin. Data Converter Interface serial data input pin. Data Converter Interface serial data output pin. C1RX C1TX C2RX C2TX I O I O ST — ST — ECAN1 bus receive pin. ECAN1 bus transmit pin. ECAN2 bus receive pin. ECAN2 bus transmit pin. PGED1 PGEC1 PGED2 PGEC2 PGED3 PGEC3 I/O I I/O I I/O I ST ST ST ST ST ST Data I/O pin for programming/debugging communication channel 1. Clock input pin for programming/debugging communication channel 1. Data I/O pin for programming/debugging communication channel 2. Clock input pin for programming/debugging communication channel 2. Data I/O pin for programming/debugging communication channel 3. Clock input pin for programming/debugging communication channel 3. IC1-IC8 I ST Capture inputs 1 through 8. INT0 INT1 INT2 INT3 INT4 I I I I I ST ST ST ST ST External interrupt 0. External interrupt 1. External interrupt 2. External interrupt 3. External interrupt 4. MCLR I/P ST Master Clear (Reset) input. This pin is an active-low Reset to the device. OCFA OCFB OC1-OC8 I I O ST ST — Compare Fault A input (for Compare Channels 1, 2, 3 and 4). Compare Fault B input (for Compare Channels 5, 6, 7 and 8). Compare outputs 1 through 8. OSC1 OSC2 I I/O ST/CMOS — Oscillator crystal input. ST buffer when configured in RC mode; CMOS otherwise. Oscillator crystal output. Connects to crystal or resonator in Crystal Oscillator mode. Optionally functions as CLKO in RC and EC modes. RA0-RA7 RA9-RA10 RA12-RA15 I/O I/O I/O ST ST ST PORTA is a bidirectional I/O port. RB0-RB15 I/O ST PORTB is a bidirectional I/O port. RC1-RC4 RC12-RC15 I/O I/O ST ST PORTC is a bidirectional I/O port. RD0-RD15 I/O ST PORTD is a bidirectional I/O port. RE0-RE7 I/O ST PORTE is a bidirectional I/O port. RF0-RF8 RF12-RF13 I/O I/O ST ST PORTF is a bidirectional I/O port. Legend: CMOS = CMOS compatible input or output; Analog = Analog input; P = Power ST = Schmitt Trigger input with CMOS levels; O = Output; I = Input |
