Overview
R5F117GCGFB#10 from Renesas is a 48-pin LFQFP, 32 KB flash, 3 KB RAM, RL78/I1D 16-bit microcontroller for industrial applications (−40°C to +105°C), featuring ultra-low power consumption (58.3 μA/MHz active, 0.64 μA in RTC+LVD STOP mode), 17-channel 12-bit ADC, four operational amplifiers, two comparators, and dual simplified I²C/CSI interfaces.
For engineers reviewing the R5F117GCGFB#10 datasheet, R5F117GCGFB#10 pinout, R5F117GCGFB#10 application, or R5F117GCGFB#10 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and confirmed alternative options for industrial sensor nodes, motor control interfaces, and low-power HMI subsystems.
Technical Context
The R5F117GCGFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz high-speed on-chip oscillator or 66.6 μs at 15 kHz low-speed mode). It integrates a regulator-based power system supporting VDD = 1.6–3.6 V operation and HALT/STOP/SNOOZE low-power modes.
Its peripheral set includes a 22-source Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with background data flash rewriting (BGO), and dual serial array units enabling concurrent CSI00/CSI01 and I²C00/I²C01 operation - all synchronized to independent main/subsystem clocks (up to 20 MHz / 32.768 kHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F117GAGFB#10 | Same 48-pin LFQFP package, identical peripherals, but 16 KB code flash (vs. 32 KB) | Suitable for cost-sensitive designs with smaller firmware footprints and no future feature expansion needs | Select when application firmware fits in ≤16 KB and BGO data logging volume is modest |
| R5F117BCGNA#00 | 32-pin HVQFN (5×5 mm), 32 KB flash, 3 KB RAM, but only 26 I/O pins and no 6 V-tolerant outputs | Targeted for space-constrained PCBs where analog channel count and mixed-voltage interfacing are secondary priorities | Choose for compact designs needing same core performance but fewer GPIO and no high-voltage I/O requirements |
Compared with R5F117GAGFB#10, the R5F117GCGFB#10 doubles code flash capacity for complex control algorithms and secure boot partitions; versus R5F117BCGNA#00, it adds 16 extra I/O pins, 4× 6 V-tolerant outputs, and enhanced analog channel count - making it optimal for industrial sensor aggregation and multi-peripheral coordination.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F117GCGFB#10?
The R5F117GCGFB#10 features a high-speed on-chip oscillator rated up to 24 MHz with ±1.0% accuracy across −20°C to +85°C at VDD = 1.8–3.6 V. At industrial temperature extremes (−40°C to +105°C), accuracy degrades to ±2.0% under 2.4–3.6 V operation. This oscillator serves as the default reset clock source and supports dynamic switching to reduce power during idle periods.
How many analog input channels does R5F117GCGFB#10 support, and what is their resolution?
The R5F117GCGFB#10 supports 17 analog input channels (ANI0–ANI13, ANI16–ANI18) with 12-bit resolution and VDD-referenced conversion. The ADC operates across the full 1.6–3.6 V supply range and includes an internal 1.45 V reference and integrated temperature sensor - enabling direct measurement of thermistors, RTDs, and voltage dividers without external references.
Does R5F117GCGFB#10 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F117GCGFB#10 supports Background Operation (BGO) for data flash rewriting. While the CPU executes instructions from code flash memory, the flash control unit concurrently rewrites the 2 KB data flash area - enabling uninterrupted real-time processing during firmware updates, calibration storage, or event logging without halting application code.
What are the key low-power modes available in R5F117GCGFB#10, and what is the lowest achievable current draw?
The R5F117GCGFB#10 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC2 and LVD active, it achieves 0.64 μA typical current draw at 25°C. This ultra-low state retains RAM content and enables wake-up via external interrupt, RTC alarm, or LVD threshold crossing - ideal for decade-long battery operation in remote sensor deployments.
Can R5F117GCGFB#10 interface directly with both 1.8 V and 3.3 V peripherals?
Yes, the R5F117GCGFB#10 supports different-potential interfacing: its 42 GPIO include 4× N-ch open-drain pins (P60–P63) rated for 6 V tolerance, allowing safe connection to 1.8 V or 2.5 V devices without level shifters. Additionally, port pins can be configured with on-chip pull-up resistors and TTL input buffers to match varying logic thresholds across mixed-voltage systems.
