Product details
Overview
R5F100GCAFB#50 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for battery-powered industrial control and sensor interface applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100GCAFB#50 datasheet, R5F100GCAFB#50 pinout, R5F100GCAFB#50 application, or R5F100GCAFB#50 equivalent, key selection criteria include ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated LIN-capable UART, and on-chip debug with flash self-programming support.
Technical Context
The R5F100GCAFB#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-mode RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, 2–8× CSI (SPI-compatible) channels, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time response in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GDAFB#50 | Same package and memory (128 KB flash/8 KB data flash/12 KB RAM), but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade) | Targeted at consumer or standard industrial environments without extended temperature requirements | Select when ambient operating temperature stays ≤ +85°C and cost optimization is prioritized over extended thermal margin |
| R5F101GCAFB#50 | Identical pinout and package, but lacks data flash memory (0 KB); retains full code flash, RAM, and peripheral set | Suitable where firmware-only updates suffice and persistent parameter storage is handled externally or via EEPROM | Choose when data logging or field-upgradable configuration storage is unnecessary - reduces cost and simplifies qualification |
Compared with R5F100GCAFB#50, R5F100GDAFB#50 trades extended temperature tolerance for lower cost in milder environments, while R5F101GCAFB#50 removes data flash to streamline firmware-only use cases - both retain identical peripheral functionality and footprint compatibility.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100GCAFB#50?
The R5F100GCAFB#50 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0%). At this frequency, it consumes 66 μA per MHz in HALT mode. In STOP mode with only RTC and LVD active, current drops to 0.57 μA - enabling decade-long battery life in intermittent-sensing applications. The R5F100GCAFB#50 achieves this via adaptive clock gating and segmented power domain control.
Does the R5F100GCAFB#50 support in-system programming and secure firmware updates?
Yes, the R5F100GCAFB#50 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for firmware protection. Its self-programming capability enables field firmware updates without external tools, and the boot swap function ensures fail-safe upgrades. These capabilities are fully implemented in the R5F100GCAFB#50 silicon.
How many analog input channels does the R5F100GCAFB#50 support, and what ADC resolution is available?
The R5F100GCAFB#50 integrates a 10-bit successive approximation ADC with up to 26 configurable analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins. It also provides an internal 1.45 V reference voltage and integrated temperature sensor - all accessible without external components. This ADC configuration is fixed and verified for the R5F100GCAFB#50.
Is the R5F100GCAFB#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GCAFB#50 is pin-compatible with all 48-pin LFQFP variants in the RL78/G13 family (e.g., R5F100GDAFB#50, R5F100GEAFB#50), sharing identical pin functions, electrical characteristics, and mechanical footprint. This allows direct substitution within the same package group when memory or grade requirements change - confirmed by Renesas' official pin compatibility documentation for the R5F100GCAFB#50.
What communication interfaces are integrated into the R5F100GCAFB#50, and which support LIN bus protocol?
The R5F100GCAFB#50 integrates UART, I²C, and CSI (SPI-compatible) interfaces. Two UART channels explicitly support LIN bus physical layer compliance (ISO 17987), including break detection, sync byte handling, and checksum generation - validated in Renesas' RL78/G13 hardware manual for the R5F100GCAFB#50. No external transceiver is needed for basic LIN node implementation.
