Product details
Overview
R5F100GCAFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC calendar, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GCAFB#30 datasheet, R5F100GCAFB#30 pinout, R5F100GCAFB#30 application, or R5F100GCAFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 7×7 mm 0.5-mm pitch package, on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100GCAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a DMA controller (4 channels), 16-bit × 16-bit multiplier/divider/MAC unit, and dual voltage domains enabling 1.8/2.5/3.0 V interface compatibility.
Its power management includes on-chip POR and LVD with 14 selectable threshold levels, real-time clock with calendar/alarm/correction functions, and watchdog timer operable from dedicated low-speed oscillator - all designed for deterministic low-power operation in resource-constrained embedded systems without external timing or reset components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GDAFB#30 | Same package and pinout; 128 KB flash, 8 KB data flash, but rated for -40°C to +85°C (D-grade) instead of +105°C. | Suitable for commercial/industrial ambient environments without extended thermal stress; lower cost where full G-grade qualification is unnecessary. | Select when operating temperature remains ≤+85°C and cost optimization is prioritized over extended thermal margin. |
| R5F101GCAFB#30 | Identical footprint and peripherals, but lacks data flash (0 KB); retains same 128 KB code flash, 12 KB RAM, and G-grade temperature range. | Applicable where non-volatile parameter storage is handled externally or via EEPROM emulation in code flash - reduces BOM count if data flash not required. | Choose when firmware does not require background data logging or field-upgradable configuration storage, simplifying flash management. |
