FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LCGFB#V0?
The R5F100LCGFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction execution times - as fast as 0.03125 μs in high-speed mode using the on-chip oscillator. This makes the R5F100LCGFB#V0 suitable for real-time control loops and protocol stack processing in resource-constrained designs.
Does the R5F100LCGFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100LCGFB#V0 supports self-programming of both code and data flash memory with features including boot swap functionality and flash shield window protection. The 8 KB data flash supports background operation (BGO), allowing code execution from program memory while rewriting - enabling safe, atomic firmware updates without halting system operation. Security is enhanced by block-erase prohibition and on-chip debug lock.
What low-power modes are available on the R5F100LCGFB#V0, and what is the lowest current consumption?
The R5F100LCGFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - ideal for battery-backed timekeeping and periodic wake-up applications. HALT mode draws 66 μA/MHz, and SNOOZE mode enables selective peripheral operation while CPU remains halted. All modes retain RAM content and support multiple wake-up sources including interrupts and RTC alarms.
How many analog input channels and what ADC resolution does the R5F100LCGFB#V0 provide?
The R5F100LCGFB#V0 integrates a 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 - both accessible via dedicated ANI pins. The ADC supports simultaneous sampling on multiple channels and operates across the full 1.6–5.5 V supply range, making it suitable for direct sensor interfacing without external signal conditioning in many cases.
Is the R5F100LCGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LCGFB#V0 is pin-compatible with all other RL78/G13 MCUs in the 64-pin LFQFP (FB) package, including R5F100LGAFB#V0 and R5F101LCDFB#V0. Pin functions are consistent across the family, enabling hardware reuse and migration paths. However, differences in flash size, data flash presence, and RAM capacity require software validation during substitution - especially for memory-mapped drivers and bootloader configurations.
