Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFA#30 | Same package and pinout; 128 KB flash, 12 KB RAM, but 8 KB data flash vs. R5F100MFAFA#30's 8 KB - identical memory map | No functional difference; variant differs only in factory programming (e.g., bootloader presence) | Select when requiring Renesas-certified pre-flashed firmware image or specific security configuration |
| R5F101MFAFA#30 | Identical package, pinout, and peripherals, but lacks data flash memory (0 KB vs. 8 KB); otherwise same 128 KB code flash and 12 KB RAM | Not suitable for applications requiring non-volatile parameter storage or field firmware updates without external EEPROM | Choose only if data flash functionality is unnecessary and cost reduction is prioritized over field upgrade capability |
Compared with R5F100MFAFA#30, R5F100MGAFA#30 offers identical functionality with potential firmware differentiation, while R5F101MFAFA#30 removes data flash-reducing BGO capability and eliminating in-field parameter retention, making it unsuitable for adaptive or upgradable systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MFAFA#30?
The R5F100MFAFA#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This rating is measured under standard conditions (VDD = 1.8–5.5 V, TA = –40°C to +85°C) and reflects the RL78 CPU core's optimized 3-stage pipeline execution efficiency at full speed.
Does the R5F100MFAFA#30 support in-system programming and secure flash protection?
Yes, the R5F100MFAFA#30 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features. These mechanisms prevent unauthorized read/write access to code flash, enabling secure firmware updates and IP protection during field deployment.
What are the supported low-power modes and their typical current consumption for the R5F100MFAFA#30?
The R5F100MFAFA#30 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE modes. STOP mode maintains RTC calendar and LVD monitoring while disabling CPU and most peripherals-ideal for battery-backed timekeeping and wake-on-event applications.
Can the R5F100MFAFA#30 perform ADC conversions while executing code from flash memory?
Yes, the R5F100MFAFA#30 supports concurrent ADC operation and program execution. Its 10-bit ADC can acquire up to 26 analog inputs with programmable scan sequences and trigger-based sampling, all without halting CPU execution-enabling real-time sensor fusion in control loops.
Is the R5F100MFAFA#30 pin-compatible with other RL78/G13 80-pin variants such as R5F100MGAFA#30?
Yes, the R5F100MFAFA#30 is fully pin-compatible with all RL78/G13 80-pin LQFP-0.65mm variants including R5F100MGAFA#30, R5F100MHAFA#30, and R5F100MJAFA#30.
