## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XIN | input | Crystal oscillator input supporting parallel resonant AT-cut fundamental crystals and ceramic resonators; it can also be an external clock input and must not be left floating. |
| 2 | XOUT | output | Crystal oscillator output that serves as the output of the crystal amplifier for parallel resonant AT-cut crystals and ceramic resonators. |
| 3 | DGND | power_in | Digital ground. |
| 4 | RST | input | Holding the reset input high for two tOSC periods resets the device. |
| 5 | NC | unconnected | No connection; leave unconnected. |
| 6 | AVDD | power_in | Analog power supply; absolute maximum AVDD to AGND is −0.3 V to +6 V and the device supply range is 2.7 V to 5.25 V. |
| 7 | AGND | power_in | Analog ground. |
| 8 | AGND | power_in | Analog ground. |
| 9 | AINCOM | input | Analog input that can serve as analog common for single-ended inputs or as an analog input for differential inputs. |
| 10 | IDAC | output | Output of the on-chip 8-bit current DAC. |
| 11 | REFOUT/REFIN+ | bidirectional | Internal voltage reference output or voltage reference positive input; requires CREF = 0.1 µF. |
| 12 | REFIN− | input | Voltage reference negative input; tie to AGND to use the internal voltage reference. |
| 13 | AIN5 | input | Analog input channel 5, usable as differential or single-ended input. |
| 14 | AIN4 | input | Analog input channel 4, usable as differential or single-ended input. |
| 15 | AIN3 | input | Analog input channel 3, usable as differential or single-ended input. |
| 16 | AIN2 | input | Analog input channel 2, usable as differential or single-ended input. |
| 17 | AIN1 | input | Analog input channel 1, usable as differential or single-ended input. |
| 18 | AIN0 | input | Analog input channel 0, usable as differential or single-ended input. |
| 19 | P1.0 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function PROG is the serial programming mode select, which must be DGND on reset. |
| 20 | P1.1 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH) with no alternate function listed. |
| 21 | P1.2 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function DOUT is the serial data output. |
| 22 | P1.3 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function DIN is the serial data input. |
| 23 | P1.4 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate functions are external interrupt 2 and Slave Select (INT2/SS). |
| 24 | P1.5 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function is external interrupt 3 (INT3). |
| 25 | P1.6 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function is external interrupt 4 (INT4). |
| 26 | DGND | power_in | Digital ground. |
| 27 | DVDD | power_in | Digital power supply; absolute maximum DVDD to DGND is −0.3 V to +6 V. |
| 28 | P1.7 | bidirectional | Port 1 bidirectional I/O (direction set by P1DDRL/P1DDRH); alternate function is external interrupt 5 (INT5). |
| 29 | P3.0 | bidirectional | Port 3 bidirectional I/O (direction set by P3DDRL/P3DDRH); alternate function RxD0 is the serial port 0 input. |
| 30 | P3.1 | bidirectional | Port 3 bidirectional I/O (direction set by P3DDRL/P3DDRH); alternate function TxD0 is the serial port 0 output. |
| 31 | P3.2 | bidirectional | Port 3 bidirectional I/O (direction set by P3DDRL/P3DDRH); alternate function INT0 is external interrupt 0. |
| 32 | P3.3 | bidirectional | Port 3 bidirectional I/O (direction set by P3DDRL/P3DDRH); alternate function INT1 is external interrupt 1. |
| 33 | P3.4 | bidirectional | Port 3 bidirectional I/O (direction set by P3DDRL/P3DDRH); alternate function T0 is the Timer 0 external input. |
