Product details
Overview
R5F101GGAFB#30 from Renesas is a 48-pin LFQFP, 5 V-tolerant 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, designed for ultra-low-power industrial control applications operating from –40°C to +105°C. It delivers 41 DMIPS at 32 MHz, supports 6–26-channel 10-bit ADC, real-time clock with calendar, and multiple serial interfaces including UART, I²C, and CSI.
For engineers reviewing the R5F101GGAFB#30 datasheet, R5F101GGAFB#30 pinout, R5F101GGAFB#30 application, or R5F101GGAFB#30 equivalent, key selection criteria include its G-grade industrial temperature rating, absence of on-chip data flash, 48-pin LFQFP-0.5 mm package, and integrated low-voltage detection with 14-level programmable reset thresholds.
Technical Context
The R5F101GGAFB#30 implements the RL78 CPU core with a 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 12-bit interval timer, 16-bit timers (up to 16 channels), and a real-time clock with alarm and calendar functions.
Power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA RTC+LVD standby current. The device features a high-accuracy ±1.0% on-chip oscillator (32 MHz max), 14-level LVD, and DMA controller with 2/4 channels supporting 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GGAFB#30?
The R5F101GGAFB#30 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas documentation. The R5F101GGAFB#30 maintains this performance across its full 1.6–5.5 V supply range and industrial temperature span.
Does the R5F101GGAFB#30 include on-chip data flash memory?
No, the R5F101GGAFB#30 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas' naming convention, it provides 96 KB of code flash and 8 KB of RAM but omits dedicated data flash. Designers requiring nonvolatile parameter storage must implement external EEPROM, FRAM, or utilize code flash sectors with wear-leveling firmware.
What package type and pin pitch does the R5F101GGAFB#30 use?
The R5F101GGAFB#30 uses a 48-pin LFQFP package with 0.5 mm pin pitch, measuring 7 mm × 7 mm. Its ordering code suffix "FB" explicitly denotes LFQFP, and "#30" indicates tray packaging. This fine-pitch QFP enables compact board layouts while maintaining compatibility with standard surface-mount assembly processes.
What is the operating temperature range certified for the R5F101GGAFB#30?
The R5F101GGAFB#30 is rated for industrial operation from –40°C to +105°C, denoted by the "G" suffix in its part number. This grade exceeds commercial (A: –40°C to +85°C) and standard industrial (D: –40°C to +85°C) specifications, making it suitable for under-hood automotive, factory-floor PLCs, and outdoor energy infrastructure where ambient extremes occur.
Which serial communication interfaces are integrated into the R5F101GGAFB#30?
The R5F101GGAFB#30 integrates UART (with LIN support), I²C/Simplified I²C, and CSI (Renesas' SPI-compatible interface), with channel counts configurable per pin mapping. Specifically, it supports up to 4 UART channels, 10 I²C channels, and 8 CSI channels - enabling concurrent connectivity to displays, sensors, CAN transceivers (via UART), and EEPROMs without external bridge ICs.
