Description
VDD 1.8V
I2C data pin. The pin can be DFC0 function by pin 3 SEL_DFC power-on latch status.
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.
Crystal oscillator interface output or differential clock input pin (CLKIN).
Crystal oscillator interface input or differential clock input pin (CLKINB).
Power supply pin for 32.768kHz DCO; usually connect to coin cell battery, 1.8V.
Connect to ground.
VDD 1.8V.
Connect to ground.
Output power supply. Connect to 1.8V. Sets output voltage levels for SE1.
Output clock SE1.
OE1’s function selected from OTP pre-programmed register bits.
OE1 pull to 6.5V when burn OTP registers.
Refer to OE Pin Functions table for details.
Output power supply. Connect to 1.8V. Sets output voltage levels for DIFF1.
