Type2 I/O75K-OHM is a typical value (in the range of 40K-OHM~190K-OHM) for others I/O that cannot be configured to different resistance. NOTE(*) In the specified software(Part#: 53tbc), NAD pin#L8 is no longer being a GPI pin as default and configured as MCU_RESET_B to support following reset function This pin is triggered high to close application software firstly, and then to do the reset of PMIC for rebooting NAD after the power-off/-on sequence Symbol Name Voltage GPIO Description Power Domain MT2731 Pin-out Internal Pull State PD GPIO46 NAD Pin#

UMC-MT2731C Product Specification 5 Thermal design 5.1 Thermal sensor
(1)There are four temperature sensors embedded in MT2731 device package. Developer could read temperature value inside MT2731 by the software command. When the package temperature reached the threshold point, MT2731 will trigger itself resetting for the over-heating protection
(2)MT2731 could get thermal information from two on board thermistors and monitor components temperature near these two thermistor locations
(3)Developer could connect four outgoing general purpose ADC interfaces, named as AUXADC_VIN2, AUXADC_VIN3, AUXADC_VIN4 and AUXADC_VIN5, of NAD for monitoring hotspots temperature on the application board 5.2 Software thermal mitigation UMC-MT2731C has software approaches for the thermal mitigation. When the temperature reached the defined threshold point, LINUX kernel will control the system power by holding processors and RF power amplifier current consumption. This will make UMC-MT2731C work safely under the critical and concerned temperature condition The information contained herein is the exclusive property of WNC and shall not be distributed, reproduced, or disclosed in whole or in part without prior written permission from WNC.

UMC-MT2731C Product Specification WATCHDOG is a 1.8-Voltage level signal generated from MT2731 and then received by PMIC. In normal cases, MT2731 keeps WATCHDOG as the high state; in case of the low state event happened, a NAD resetting reaction steps would be performed between MT2731 and PMIC and defined as below
(1) If MT2731 is malfunctioning, WATCHDOG would become the low state, as well as WDTRSTB_IN of PMIC. Then, PMIC starts itself reset
(2) After the reset of PMIC is finished, PMIC sent RESETB of the low state to SYSRSTB of MT2731. Then, MT2731 also starts itself reset procedure Rev: 0.9 Page 36 of 44
