Product details
Overview
R5F101GGAFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates a 10-bit ADC (26 channels), RTC, 16-bit timers (12 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F101GGAFB#10 datasheet, R5F101GGAFB#10 pinout, R5F101GGAFB#10 application, or R5F101GGAFB#10 equivalent, key selection criteria include its industrial-grade thermal rating, absence of on-chip data flash, LFQFP-48 7×7 mm 0.5-mm pitch package, and suitability for battery-powered industrial control, sensor nodes, and motor drive subsystems requiring deterministic real-time response and low active/idle power.
Technical Context
The R5F101GGAFB#10 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with 128 KB code flash organized in 1-KB blocks.
It features dual-clock domains: a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and a dedicated low-speed oscillator for watchdog and RTC operation. Peripheral integration includes 2 DMA channels, hardware multiplier/divider, BCD correction circuit, and configurable I/O ports supporting 1.8/2.5/3.0 V level-shifting interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GGAFA#V0 | Same core, flash, RAM, and peripherals; differs only in packaging (48-pin LQFP, 0.65-mm pitch vs. LFQFP 0.5-mm pitch) | Requires PCB footprint redesign due to larger pad pitch and body size (10×10 mm vs. 7×7 mm) | Select when legacy board design uses standard LQFP or reflow profile favors larger pitch |
| R5F100GGAFB#10 | Identical package, pinout, and peripherals but includes 8 KB data flash memory and flash shield window security | Enables field firmware updates and secure parameter storage; adds ~0.1 mA active current overhead | Select when data logging, OTA updates, or secure credential storage are required |
Compared with R5F101GGAFA#V0, the R5F101GGAFB#10 offers superior board area efficiency and thermal dissipation in the smaller LFQFP package; compared with R5F100GGAFB#10, it trades data flash capability for lower cost and marginally reduced active power, making it optimal for fixed-function industrial controllers where field updates are not needed.

Does the R5F101GGAFB#10 include on-chip data flash memory?
No, the R5F101GGAFB#10 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, this variant provides only code flash (128 KB) and 8 KB RAM. Applications requiring nonvolatile parameter storage must use external EEPROM or utilize code flash sectors with wear-leveling firmware.
What package type and dimensions does the R5F101GGAFB#10 use?
The R5F101GGAFB#10 uses a 48-pin LFQFP package measuring 7 mm × 7 mm with 0.5-mm lead pitch. Its official Renesas package code is PLQP0048KF-A, and it complies with JEDEC MS-026 standards. This compact footprint supports high-density industrial PCB layouts while maintaining manufacturability with standard SMT reflow profiles.
What is the operating temperature range certified for the R5F101GGAFB#10?
The R5F101GGAFB#10 is rated for industrial operation from –40°C to +105°C, denoted by the "G" suffix in its part number. This qualification ensures reliable functionality in harsh environments such as factory automation cabinets, outdoor metering enclosures, and motor drive heat sinks without thermal derating of performance or lifetime.
How many analog input channels does the R5F101GGAFB#10 support, and what is the ADC resolution?
The R5F101GGAFB#10 integrates a 10-bit successive approximation register (SAR) ADC with up to 26 analog input channels (ANI0–ANI25).
