The R5F100LEGFA#10 integrates a 10-bit SAR ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. These features enable direct measurement of thermistors, potentiometers, and current-sense resistors without external references or signal conditioning - reducing BOM count and board area.
Is the R5F100LEGFA#10 qualified for industrial temperature operation?
Yes, the R5F100LEGFA#10 carries the 'G' suffix indicating industrial temperature qualification from -40°C to +105°C. This makes it suitable for deployment in harsh environments such as motor drives, power supplies, and outdoor building controllers where extended thermal stability is required.
Which development tools and software support the R5F100LEGFA#10?
The R5F100LEGFA#10 is fully supported by Renesas' CS+ IDE, e² studio (Eclipse-based), and the Renesas Flash Programmer. Hardware debug is enabled via SWD using E2 or E2 Lite emulators.
