Product details
Overview
R5F100GGGNA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade -40°C to +105°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, RTC with calendar/alarm, and ultra-low-power STOP mode (0.57 μA). Used in battery-powered industrial sensors and smart metering front-ends.
For engineers reviewing the R5F100GGGNA#U0 datasheet, R5F100GGGNA#U0 pinout, R5F100GGGNA#U0 application, or R5F100GGGNA#U0 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) footprint, G-grade temperature rating, integrated data flash with 1M-cycle endurance, and support for SNOOZE-mode peripheral wake-up without CPU intervention.
Technical Context
The R5F100GGGNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and 1 MB address space. It features dual-clock domains: high-speed main system clock (up to 32 MHz) and independent subsystem clock (32.768 kHz) for RTC/LVD operation during STOP mode.
Its peripheral set includes 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2–8× CSI (SPI-compatible) channels, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM. The A/D converter provides 10-bit resolution across 26 analog inputs with internal 1.45 V reference and temperature sensor.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F100GGGNA#U0?
The R5F100GGGNA#U0 features a high-accuracy on-chip oscillator adjustable from 1 MHz to 32 MHz, with ±1.0% tolerance across VDD = 1.8–5.5 V and TA = –20°C to +85°C. At 32 MHz, it achieves a minimum instruction execution time of 0.03125 μs, eliminating the need for external crystals in many timing-critical applications while maintaining system-level accuracy.
Does R5F100GGGNA#U0 support background data flash rewriting during program execution?
Yes, the R5F100GGGNA#U0 supports background operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors-a critical capability for reliable firmware logging, calibration storage, and over-the-air parameter updates without system interruption.
What is the operating temperature range and industrial qualification status of R5F100GGGNA#U0?
The R5F100GGGNA#U0 is rated for –40°C to +105°C operation (G-grade industrial qualification) and is fully specified across this range for all key parameters including flash endurance, ADC linearity, and oscillator accuracy. It meets industrial reliability standards for use in enclosed, thermally stressed environments such as motor drives and utility metering hardware.
How many analog input channels does the ADC in R5F100GGGNA#U0 support, and what reference options are available?
The R5F100GGGNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI23 plus P147 alias), operating from 1.6 V to 5.5 V supply. Reference options include external AVREFP/AVREFM pins or an internal 1.45 V reference-selectable only in high-speed (HS) mode-and a built-in temperature sensor for system health monitoring.
Can R5F100GGGNA#U0 operate in ultra-low-power modes while maintaining RTC and LVD functionality?
Yes, the R5F100GGGNA#U0 supports STOP mode with only RTC and LVD active, consuming just 0.57 μA typical. In this state, the 32.768 kHz subsystem clock continues running the calendar, alarm, and voltage-monitoring functions-enabling precise timekeeping and brown-out detection without waking the CPU, which is essential for battery longevity in remote monitoring systems.
