FAQ
What is the maximum operating frequency of the R5F10EGAAFB#V0?
The R5F10EGAAFB#V0 supports a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator with ±1% accuracy across 1.8 V–3.6 V and −20°C to +85°C. External crystal (X1/X2) or external clock (EXCLK) sources also support up to 32 MHz, subject to voltage and temperature derating per the datasheet's electrical specifications.
Does the R5F10EGAAFB#V0 support in-system programming?
Yes, the R5F10EGAAFB#V0 supports in-system programming via its on-chip debug interface (TOOL0 pin) and serial wire debug (SWD)-compatible protocol. The 16 KB code flash includes secure boot swap and flash shield window functions, enabling field firmware updates without removing the device from the PCB.
What low-power modes are available on the R5F10EGAAFB#V0?
The R5F10EGAAFB#V0 offers Stop (0.23 µA RAM retained), Halt (0.57 µA with RTC + LVD), Snooze (0.6–0.7 mA for ADC/UART wake-up), and Active (66 µA/MHz) modes. All modes retain RAM content, and Halt mode maintains RTC timekeeping and LVD monitoring-critical for long-duration battery operation.
How many ADC channels does the R5F10EGAAFB#V0 support, and what is the resolution?
The R5F10EGAAFB#V0 supports up to 28 analog input channels with 12-bit resolution and a minimum conversion time of 3.375 µs. It includes an internal 1.45 V voltage reference and supports operation down to 1.6 V supply, enabling accurate measurements even under brown-out conditions.
Is the R5F10EGAAFB#V0 pin-compatible with other RL78/G1A family members?
No-the R5F10EGAAFB#V0 is a 48-pin LFQFP variant and is not pin-compatible with 25-pin WFLGA, 32-pin HWQFN, or 64-pin LFQFP/VFBGA RL78/G1A devices. Pin compatibility exists only within the same package type and pin count (e.g., R5F10EGx variants in 48-pin LFQFP share identical pinouts).
