Product details
Overview
R5F100GDAFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz RL78 CPU core (41 DMIPS), 10-bit 26-channel ADC, RTC, 16-bit timers, UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100GDAFB#30 datasheet, R5F100GDAFB#30 pinout, R5F100GDAFB#30 application, or R5F100GDAFB#30 equivalent, key selection criteria include its G-grade temperature range (−40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and integrated voltage detector with 14-level LVD interrupt/reset capability.
Technical Context
The R5F100GDAFB#30 implements the RL78 CISC core with 3-stage pipeline and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz), enabling dynamic power/performance trade-offs. Its memory subsystem includes 128 KB code flash (1 KB blocks), 8 KB data flash supporting background operation (BGO) and 1M write cycles, and 12 KB SRAM with dedicated flash library RAM allocation at FAF00H.
Peripherals are tightly coupled to low-power operation: DMA supports 2/4 channels with 2-clock transfers between SFR and RAM; the 10-bit ADC offers internal 1.45 V reference and temperature sensor; and serial interfaces include up to 10 I²C channels, 4 UART/LIN ports, and 8 CSI (SPI-compatible) channels - all configurable under HALT/STOP/SNOOZE modes.

The R5F100GDAFB#30 also enables background operation (BGO) for data flash writes, allowing firmware parameter updates without interrupting real-time application execution.
What are the key low-power features of the R5F100GDAFB#30 relevant for battery-powered designs?
The R5F100GDAFB#30 provides three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE. Its STOP mode retains full RTC calendar, alarm, and voltage monitoring functionality while drawing sub-microamp current - making the R5F100GDAFB#30 ideal for decade-long battery life in remote sensors and metering applications.
How many analog input channels and what ADC resolution does the R5F100GDAFB#30 provide?
The R5F100GDAFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a factory-calibrated temperature sensor. These features are accessible on dedicated pins like P20/ANI0/AVREFP and P21/ANI1/AVREFM, enabling accurate sensor measurements without external references in the R5F100GDAFB#30 implementation.
Is the R5F100GDAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP package - including R5F100GDAFB#30, R5F100GCAFB#30, and R5F100GLAFB#30 - share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory-scaling decisions, provided software accommodates differences in flash/RAM size and peripheral enablement - a key advantage of the R5F100GDAFB#30 family architecture.
