Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGFB#10 | Same package and pinout; reduced memory (64 KB flash, 4 KB data flash, 4 KB RAM) | Suitable for cost-sensitive designs with simpler firmware and smaller data logging needs | Select when application fits within 64 KB code and does not require concurrent BGO data writes |
| R5F101GCGFB#10 | Identical package and peripherals but no data flash; uses external EEPROM or FRAM for nonvolatile storage | Preferred where external nonvolatile memory is already present or higher endurance (>1M cycles) is required | Choose when data retention requirements exceed flash endurance or when external memory simplifies certification |

FAQ
What is the maximum operating frequency and performance of the R5F100GCGFB#10?
The R5F100GCGFB#10 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this via a 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -40°C to +105°C. This enables deterministic real-time response for motor control, sensor fusion, and protocol stacks without external clock components.
Does the R5F100GCGFB#10 support simultaneous code execution and data flash programming?
Yes, the R5F100GCGFB#10 supports background operation (BGO) for its 8 KB data flash. Firmware can execute instructions from code flash while rewriting data flash - critical for logging telemetry or updating configuration without interrupting real-time tasks. The flash library reserves specific RAM regions (e.g., FAF00H for R5F100xJ variants) to manage this safely.
What are the low-power capabilities of the R5F100GCGFB#10 in STOP mode?
In STOP mode, the R5F100GCGFB#10 draws just 0.57 μA while maintaining RTC operation and low-voltage detection (LVD). This ultra-low quiescent current enables multi-year battery life in applications like wireless sensor nodes or utility meters. The device wakes on RTC alarm, external interrupt, or LVD threshold crossing - all configurable without CPU intervention.
How many analog input channels does the R5F100GCGFB#10 ADC support, and what is its resolution?
The R5F100GCGFB#10 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 pins (P20/P21 for AVREFP/AVREFM). This eliminates need for external references in precision measurement applications.
Is the R5F100GCGFB#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GCGFB#10 shares identical 48-pin LFQFP pinout with all other RL78/G13 devices in the FB package (e.g., R5F100GAGFB#10, R5F100GHGFB#10). Pin functions are consistent across memory variants, enabling hardware reuse across firmware versions or feature tiers - provided software accounts for differences in flash/RAM size and peripheral enablement.
