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

UMC-STD31LF Product Specification Preventing the coplanar grounding being quite close 50-OHM RF transmission lines shall be considered by Developer when you do RF trace design connected to RF antenna pads of UMC-STD31LF on the application board. It is better to have the keep-out gap which is 3 to 5 times of top layer RF trace width between these RF lines and the grounding Meanwhile, it is also important to reserve the pi-matching circuit design close to NAD antenna out pads as possible Avoid making RF layout trace of the primary antenna port cross the diversity antenna trace, and then this would cause the poor antenna isolation to impact RF performance of the application board 8.9.1 Antenna detection Following concept schematic diagram is a design example to build the antenna detection circuit by using NAD AUXADC pin of AUXADC_VIN2 for monitoring NAD ANT_PTRX connection status with the external passive antenna shunted with a grounded inductor. In this diagram DC block: to play the role of isolating the detection signal with Antenna matching possibly consisted of the grounded matching elements RF block: to prevent RF signals being fed into the antenna detection circuitry GPIO resistor: to limit the current draw when the external antenna is connected Connected Case: NAD EINT pin would continuously send out the detection signal of the static high state; if the external antenna is well-attached with the application board, the software reading value of AUXADC_VIN2 is kept as static zero-Voltage Disconnected Case: If any broken events happened on RF path between the external antenna and NAD ANT_PTRX, AUXADC_VIN2 would read a high state voltage level generated by NAD EINT port 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.

(1) If MT2731 is malfunctioning, WATCHDOG would become the low state, as well as WDTRSTB_IN of PMIC. Then, PMIC starts itself reset

KDB 996369 D03 OEM Manual v01 rule sections:
2.2 List of applicable FCC rules This module has been tested for compliance to FCC Part 27, 22, 24, 90 2.3 Summarize the specific operational use conditions The module is tested for standalone mobile RF exposure use condition. Any other usage conditions such as co-location with other transmitter(s) or being used in a portable condition will need a separate reassessment through a class II permissive change application or new certification. 2.4 Limited module procedures Not applicable. 2.5 Trace antenna designs Refer to Operational Description Antenna trace Please contact the module supplier 2.6 RF exposure considerations This equipment complies with FCC mobile radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 22cm between the radiator & your body. If the module is installed in a portable host, a separate SAR evaluation is required to confirm compliance with relevant FCC portable RF exposure rules. 2.7 Antennas The following antennas have been certified for use with this module; antennas of the same type with equal or lower gain may also be used with this module. The antenna must be installed such that 22 cm can be maintained between the antenna and users. Antenna Type Antenna connector Dipole SMA 2.8 Label and compliance information The final end product must be labeled in a visible area with the following:
Contains FCC ID: NKRUMC-STD31LFN. The grantee's FCC ID can be used only when all FCC compliance requirements are met. 2.9 Information on test modes and additional testing requirements This transmitter is tested in a standalone mobile RF exposure condition and any co-located or simultaneous transmission with other transmitter(s) or portable use will require a separate class II permissive change re-
evaluation or new certification. 2.10 Additional testing, Part 15 Subpart B disclaimer This transmitter module is tested as a subsystem and its certification does not cover the FCC Part 15 Subpart B (unintentional radiator) rule requirement applicable to the final host. The final host will still need to be reassessed for compliance to this portion of rule requirements if applicable. As long as all conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.

UMC-STD31LF Product Specification IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. OEM/Host manufacturer responsibilities OEM/Host manufacturers are ultimately responsible for the compliance of the Host and Module. The final product must be reassessed against all the essential requirements of the FCC rule such as FCC Part 15 Subpart B before it can be placed on the US market. This includes reassessing the transmitter module for compliance with the Radio and EMF essential requirements of the FCC rules. This module must not be incorporated into any other device or system without retesting for compliance as multi-radio and combined equipment Industry Canada statement:
This device complies with ISEDs licence-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Le prsent appareil est conforme aux CNR d ISED applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes : (1) le dispositif ne doit pas produire de brouillage prjudiciable, et (2) ce dispositif doit accepter tout brouillage reu, y compris un brouillage susceptible de provoquer un fonctionnement indsirable. This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with greater than 32cm between the radiator & your body. Radiation Exposure Statement:
Dclaration d'exposition aux radiations:
Cet quipement est conforme aux limites d'exposition aux rayonnements ISED tablies pour un environnement non contrl. Cet quipement doit tre install et utilis plus de 32 cm entre le radiateur et votre corps. This device is intended only for OEM integrators under the following conditions:
