Renesas R5F100GDGFB#30

Overview

R5F100GDGFB#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 1.6–5.5 V at -40°C to +105°C (industrial grade G), delivering 41 DMIPS at 32 MHz for low-power embedded control in motor drives, sensor nodes, and industrial HMI.

For engineers reviewing the R5F100GDGFB#30 datasheet, R5F100GDGFB#30 pinout, R5F100GDGFB#30 application, or R5F100GDGFB#30 equivalent, key selection considerations include its integrated RTC with calendar/alarm, 10-bit 26-channel ADC with internal temperature sensor, ultra-low-power STOP mode (0.57 μA), and hardware multiplier/divider supporting real-time control math.

Technical Context

The R5F100GDGFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: main system clock (up to 32 MHz) and independent low-speed on-chip oscillator for watchdog and RTC operation.

Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and clock correction, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, and DMA controller with 4 channels enabling background data flash rewriting during program execution.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100GDGFB#30?

The R5F100GDGFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS (Dhrystone MIPS). Its minimum instruction execution time is 0.03125 μs under this condition, enabling deterministic timing for real-time control tasks such as motor commutation and sensor sampling.

Does the R5F100GDGFB#30 support hardware debugging and in-system programming?

Yes, the R5F100GDGFB#30 includes full on-chip debug functionality compliant with Renesas E1/E20 emulators. It supports self-programming of both code and data flash memory with boot swap and flash shield window features-enabling secure firmware updates without external programmers.

What are the low-power modes supported by the R5F100GDGFB#30, and what is the lowest current consumption?

The R5F100GDGFB#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - verified across the full -40°C to +105°C industrial temperature range - making it ideal for battery-backed applications requiring long-term calendar timekeeping.

How many analog input channels and what ADC resolution does the R5F100GDGFB#30 provide?

The R5F100GDGFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25). It includes an internal 1.45 V reference voltage and temperature sensor, both selectable only in high-speed main mode, enabling accurate sensor measurements without external components.

Is the R5F100GDGFB#30 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 48-pin LFQFP package (e.g., R5F100FAFB#30, R5F100GAFB#30, R5F101GDGFB#30) share identical pinouts and electrical characteristics. This allows seamless migration between memory/configurations without PCB redesign - provided peripheral usage aligns with the selected variant's feature set.
