Is it possible to measure the current consumption of a module unit using the evaluation kit?
Yes. The evaluation kit has a JP pin for measuring the current consumption of a module unit. Refer to the "Evaluation Kit Hardware Manual" for details.
Is there any tool for measuring current consumption?
Yes. Use ble_app_pwr_profiling app included in nRF5 SDK from Nordic to make current consumption measurements. However, code rewrite is required to enable DCDC mode. For details on the code rewrite method, etc., refer to the Application Note (Current Consumption Measurement)
What is the average current? Is there any tool for calculating current consumption?
Using our evaluation kit mini, the average current consumptions are measured as follows: MK71511: 95 uA MK71521: 113 uA Power supply voltage: 3.0 V, DCDC regulator: ON, transmission power: 0 dBm, status: Connection, Interval: 30 ms For detailed data and the description of the current consumption measuring method, refer to "Application Note (Current Consumption Measurement)". You can use the nRF52 Online Power Profiler from Nordic to make an estimate. Since nRF52832 is mounted on MK71521, please select "nRF52832" for Chip. https://devzone.nordicsemi.com/nordic/power/ Please note that the nRF52811 mounted on MK71511 cannot be selected for Chip with nRF52 Online Power Profiler. Refer to measurement results described in "Application Note (Current consumption measurement)".
How much electric current when inputting the external clock to XT pin at power down?
At power down, since the first degree current path is cut, the current flows little and only the leak current when the signal is input from XT. The current flows when input from XTB. Related Products: ML2272x/76x, ML2282x/86x
How does the current measurement is performed?
Current measurement is done with measuring the voltage of shunt resistor connected externally.
Is LE Audio supported?
No, it is not supported. LE Audio is an optional feature of Bluetooth v5.2. Neither MK71511 nor MK71521 supports this function.
Battery connection order is designated?
Please refer to each datasheet. Basically, GND, VDD are connected first, and connect each battery terminal. Disconnection order is reverse.
When should I set the high-impedance output that can be set in the port n control registers (PnC0, PnC1)?
The pins become open in high-impedance output mode, thus eliminating the current path for the pins. Please set the high-impedance output when you do not want to set the "H" or "L" level to a connection destination, or when the pins are not used. Also, the current path for the pins can be eliminated when no pull-up/pull-down resistor is used in high-impedance input mode. However, this may cause a pass-through current to flow in the input circuit if the pins become intermediate potential, thus increasing the current consumption. Please set the unused pins to high-impedance output mode.

What is the difference between power-down mode and power-save mode?
In power-down state all circuits except powerup is stopped to reduce power consumption. In power-save state, circuits for measuring cell voltage and current is stopped to reduce power consumption.
Please tell me how to check the ROM size for each file.
If you check [Do not generate separate segment per function] in the compiler option settings (Properties> Settings> Tool Settings tab Compiler> Code Generation) of LEXIDE-U16, you can prevent the segment from being divided into function units. From this, you can check the ROM consumption of each file in the map file. At this time, the segment name for the function is $$NCODfilename or $$FCODfilename, and the segment name of the constant data is $$NTABfilename or $$FTABfilename, so check the map file. However, if you set this option, the code size may increase because unreferenced functions and constant data are also included in the segments of the file. Also, please understand that the ROM consumption is not an accurate value because the HEX data for each file may change slightly.

Are there any special functions or know-how to save power consumption?
Intermittent operation performed in Deep-HALT mode, which is an industry-leading function for saving the standby current of the low-speed clock, can help reducing the average power consumption. Deep-HALT mode can be released by a timer. Also, power consumption can be reduced by stopping the operation of the unused circuits with the block control function.

We are developing software using IDEU8. When I start the debugger of DTU8 from IDEU8, the error dialog "Source file not found" is displayed. I can see the assembly code but not the C source code.
It is assumed that no debug information is included. Please check "Compile/Assemble Options" and "Target Options" in IDEU8. [Compile/Assemble Options] Check "Print debug information" in the "General" tab. [Target option] Check "Print debug information" in the "General" tab. After setting the above, build again and restart DTU8.
In addition to the A/D conversion time, are there any other considerations for A/D conversion in the ML62Q1000 series?
Please also note the sample hold time. To calculate the optimum sample hold time, refer to "23.4 Notes on SA-ADC" in the user's manual. Related Products: ML62Q12xx, ML62Q13xx, ML62Q14xx, ML62Q15xx/ML62Q18xx, ML62Q16xx, ML62Q17xx
