Current Consumption Calculator

Q: Can decimal values be used for the time and period settings of peripheral functions?

A: No, decimal values are not supported. Please use integer values.

Q: The current consumption calculator is not displaying correctly.

A: If you are using Internet Explorer 11, please disable Enterprise Mode. The current consumption calculator does not work in Enterprise Mode. If you are not in Enterprise Mode and the tool still doesn't work, please use Firefox or Google Chrome instead.

Q: Are the current values that are displayed guaranteed values?

A: No, the current values that are displayed are reference values only, and they are not guaranteed. They are reference current values for standard samples at 25°C.

Q: Can current values be calculated at temperatures other than 25°C?

A: No. Current values can only be calculated at 25°C.

Q: Can the combinations that can be set in the current consumption calculator be selected by microcontroller?

A: Some combinations cannot be selected. Please refer to the user's manual for details.

Q: What length of period can be measured?

A: If milliseconds is selected in the time settings, a period from 0 to 60 seconds can be measured. If microseconds is selected in the time settings, a period from 0 to 60 milliseconds can be selected.

Q: Where is the battery-life calculation result displayed?

A: Hover the mouse cursor over graph to show the battery life.

Q: How do I use snapshots?

A: Up to four sets of set conditions can be saved as snapshots, and be used to compare graphs.
Save - Display calculated results and select a data number (1 to 4) to save. Set conditions and the graph will be saved.
Restore - Select a data number (1 to 4) to restore the set conditions and graph.
Compare - Compare the currently displayed graph with a saved graph.

Q: Can graph data be saved?

A: Select save to save graph data as a CSV file.

Q: The names of peripheral functions are displayed in blue and black? What do the colors mean?

A: Functions that are in use are displayed in blue. Functions that are not in use are displayed in black.

Q: What about current values for other RL78 Groups?

A: We plan to expand the lineup of supported products going forward.

Virtual Board Simulator and Current Consumption Simulator

Q: How do I use the virtual board simulator?

A: The procedure is as follows.
1. Extract the board panel that you would like to use. After extraction, place the two files in the same folder.
2. Load the simulator. In the simulator GUI window, open the input/output panel file (file extension ".pnl") of the virtual board that you extracted in step 1.

Q: I'm not sure how to use e2 studio and/or the current consumption simulator.

A: Please refer to the instructions (http://resource.renesas.com/resource/lib/eng/websimulator/howto.html) here.

Q: Can I use application notes with the virtual board simulator other than the ones that are posted on the web simulator site? (http://resource.renesas.com/resource/lib/eng/websimulator/index.html)

A: Application notes for products that are supported by the virtual board simulator may be used. Please check the web simulator site (http://resource.renesas.com/resource/lib/eng/websimulator/index.html) to see the RL78 products that are supported by the virtual board simulator. Please be aware that operating times on the simulator differ from operating times on a real machine. For example, a program that makes an LED blink in 1-second intervals will not blink at exact 1-second intervals on the simulator.
