The R5F100MGAFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 μs due to its 3-stage pipeline RL78 CPU core. This performance delivers 41 DMIPS, sufficient for real-time control loops and protocol stack processing in resource-constrained systems.
Does the R5F100MGAFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100MGAFB#V0 supports full in-system programming via its on-chip debug interface and self-programming capability. It includes boot swap functionality and flash shield window protection to prevent unauthorized access during firmware updates - critical for secure over-the-air (OTA) deployment in fielded R5F100MGAFB#V0-based devices.
How many analog input channels does the R5F100MGAFB#V0 support, and what is the ADC resolution?
The R5F100MGAFB#V0 supports up to 26 analog input channels with configurable 8-bit or 10-bit resolution. Its ADC operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference voltage and factory-calibrated temperature sensor - enabling accurate ratiometric measurements without external components.
What low-power modes are available on the R5F100MGAFB#V0, and what is the lowest achievable current draw?
The R5F100MGAFB#V0 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified across –40°C to +105°C. This enables decade-scale battery life in always-on sensor and metering applications using the R5F100MGAFB#V0.
Is the R5F100MGAFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100MGAFB#V0 is fully pin-compatible with all other RL78/G13 MCUs in the 80-pin LFQFP (FB) package, including R5F100MHAFB#V0 and R5F101MGAFB#V0.
