Pin Descriptions Number Name Type Description 1VDDA Power VDD 1.8V 2SDA_DFC0 I/O I2C data pin. The pin can be DFC0 function by pin 3 SEL_DFC power-on latch status. 3 SEL_DFC/ SCL_DFC1 Input I2C CLK pin. SEL_DFC is a latch input pin during the power-up. High on power-on: I2C mode as SCLK function. Low on power-on: pin 3 SCL and pin 2 SDA as DFC function control pins. 4 CLKIN/X2 I/O Crystal oscillator interface output or differential clock input pin (CLKIN). 5 CLKINB/X1 Input Crystal oscillator interface input or differential clock input pin (CLKINB). 6VBAT Power Power supply pin for 32.768kHz DCO; usually connect to coin cell battery, 1.8V. 7VSS Power Connect to ground. 8VDD18 Power VDD 1.8V. 9VSSSE1 Power Connect to ground. 10 VDDSE1 Power Output power supply.
