Note * 1 : The output voltage of VBUCK4 depends on the status of U2.28 pin and to supply the voltage
to the internal DDR memory and DDR PHY of the target chip MA35D16A887C (MCP package with
DDR3L SDRAM memory). By default, the U2.28 pin is pull-down to force VBUCK4 pin of PMIC to
output 1.35V on this NuMaker-SOM-MA35D16A81 board.
Note *
2
: No connection (NC) by default. For more detailed information about how to change the output
voltage on VLDO4, please refer to the PMIC DA9062-3A Application Note on Nuvoton website .

1
: This PD6 pin is dedicated as PMIC_I2C0_SDA function for controlling external PMIC by
default.
Note *
2
: This PD7 pin is dedicated as PMIC_I2C0_SCL function for controlling external PMIC by
default.
Note *
3
: This PA15 pin is dedicated as PMIC_nIRQ input function from external PMIC by default.
Note *
4
: This SYS_EN input pin of PMIC device DA9062-3A (U2) is controlled by RTC_RPWR output
of MA35D1 by default. (The R89 resistor is mounted, but R88 resistor is NC by default)
Note * 5 : This RTC_RPWR output pin state of MA35D1 is controlled by RTC internal logic and the
RTC_nRWAKE input pin state of the target chip MA35D16A887C. The RTC_nRWAKE input pin is
controlled directly by the RTC Wake-up key (SW3) on NuMaker-BASE-MA35D1B1 board by default.
(The R90 resistor is NC by default)
