Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHDFB#V0 | Same 128 KB flash/8 KB data flash/12 KB RAM, but in 80-pin LFQFP (0.5 mm pitch); identical core/peripherals | Requires PCB layout change due to finer pitch and different land pattern; suitable for space-constrained designs | Select when board area optimization justifies re-spinning for smaller footprint and higher I/O density |
| R5F100LHDFA#V0 | 64-pin LQFP variant with same 128 KB flash/8 KB data flash/12 KB RAM; reduced I/O count (48 vs. 64 GPIO) | Lower pin count limits peripheral expansion (e.g., fewer UART/I²C channels); suited for cost-optimized, function-limited designs | Choose when full 80-pin I/O capability is unnecessary and BOM cost reduction is prioritized |
Compared with R5F100MHDFA#V0, R5F100MHDFB#V0 offers identical functionality in a denser package requiring layout revision, while R5F100LHDFA#V0 provides the same memory and core performance in a lower-pin-count, lower-cost package with reduced peripheral scalability.

FAQ
What is the maximum operating frequency and performance of the R5F100MHDFA#V0?
The R5F100MHDFA#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction execution times - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode - enabling precise trade-offs between throughput and power consumption in real-time applications.
Does the R5F100MHDFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F100MHDFA#V0 supports full self-programming of both code and data flash memory, including boot swap functionality and flash shield window protection. This enables secure, field-upgradable firmware with tamper resistance - critical for deployed industrial and consumer devices requiring long-term maintenance.
What low-power modes are available on the R5F100MHDFA#V0, and what is the lowest current draw?
The R5F100MHDFA#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - making it suitable for decade-long battery operation in remote monitoring and sensor logging applications where periodic wake-up is required.
How many analog input channels and what ADC resolution does the R5F100MHDFA#V0 provide?
The R5F100MHDFA#V0 integrates an 8/10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - allowing accurate voltage, current, and thermal measurements without external reference or sensor components.
Is the R5F100MHDFA#V0 pin-compatible with other RL78/G13 variants like R5F100MHDFB#V0 or R5F100LHDFA#V0?
No, the R5F100MHDFA#V0 is not pin-compatible with R5F100MHDFB#V0 (80-pin LFQFP, 0.5 mm pitch) or R5F100LHDFA#V0 (64-pin LQFP). Each has distinct pin counts, pitches, and I/O mappings. Migration requires PCB redesign; however, software compatibility is maintained across the RL78/G13 family via common toolchain and peripheral register layout.
