Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PB5/TM3PWM/PG0PWM | bidirectional | Port B bit 5 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as the PWMG0 output and the Timer3 output (TM3PWM); it can wake the system from sleep when PBDIER bit 5 is 1. |
| 2 | PB6/TM3PWM/CIN2-/PG1PWM | bidirectional | Port B bit 6 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as comparator negative input 2, Timer3 output and PWMG1 output; disable PBDIER bit 6 when used as an analog input to reduce leakage. |
| 3 | VDD | power_in | Positive power supply; operating voltage is 2.0 V to 5.5 V (limited by the selected LVR level), and the voltage must not exceed 5.5 V or the IC may be damaged. |
| 4 | PA7/X1 | bidirectional | Port A bit 7 is a programmable I/O with weak pull-up, or the X1 crystal/resonator pin when the external oscillator is used; PADIER bit 7 should be cleared to reduce leakage in crystal mode. |
| 5 | PA6/X2 | bidirectional | Port A bit 6 is a programmable I/O with weak pull-up, or the X2 crystal/resonator pin when the external oscillator is used; PADIER bit 6 should be cleared to reduce leakage in crystal mode. |
| 6 | PB7/TM3PWM/CIN3-/PG1PWM | bidirectional | Port B bit 7 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as comparator negative input 3, Timer3 output and PWMG1 output; disable PBDIER bit 7 when used as an analog input to reduce leakage. |
| 7 | PA5/PRST#/PG2PWM | bidirectional | Port A bit 5 is an open-drain-only output (external pull-up required when driven high) that can serve as the external reset input PRST# (CLKMD bit 0 = 1) or the PWMG2 output (not supported by the emulator); a 33 Ω series resistor is recommended when used as an input in noisy systems. |
| 8 | PB2/TM2PWM/PG2PWM | bidirectional | Port B bit 2 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as the Timer2 output and PWMG2 output; disable PBDIER bit 2 when used as an analog input to reduce leakage. |
| 9 | PB1 | bidirectional | Port B bit 1 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, and can wake the system from sleep when PBDIER bit 1 is 1. |
| 10 | PB0/INT1/COM1 | bidirectional | Port B bit 0 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as external interrupt INT1 (rising or falling edge), and as LCD COM1 when the VDD/2 bias is enabled. |
| 11 | GND | power_in | Ground reference for the device. |
| 12 | PA0/INT0/COM2/CO/PG0PWM | bidirectional | Port A bit 0 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as external interrupt INT0 (rising and falling edges), comparator output CO, LCD COM2 and PWMG0 output; PADIER bit 0 must be 1 for wake-up and interrupt use. |
| 13 | PA3/TM2PWM/COM4/CIN1-/PG2PWM | bidirectional | Port A bit 3 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as Timer2 output, comparator negative input 1, LCD COM4 and PWMG2 output; disable PADIER bit 3 when used as an analog input to reduce leakage. |
| 14 | PA4/COM3/CIN+/CIN4-/PG1PWM | bidirectional | Port A bit 4 is a Schmitt-trigger I/O with programmable input/output and weak pull-up, also serving as LCD COM3, comparator positive input, comparator negative input 4 and PWMG1 output; disable PADIER bit 4 when used as an analog input to reduce leakage. |
