Product details
Overview
R5F100GDGNA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GDGNA#U0 datasheet, R5F100GDGNA#U0 pinout, R5F100GDGNA#U0 application, or R5F100GDGNA#U0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, and hardware DMA for low-CPU-overhead peripheral data movement.
Technical Context
The R5F100GDGNA#U0 implements the RL78 CPU core with 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 dual-clock domains: high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C interfaces, 2–4× UART/LIN channels, 2–8× CSI/SPI channels, and background operation-capable data flash (1M rewrite cycles, 1.8–5.5 V programming voltage), enabling concurrent code execution and nonvolatile storage updates.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GDGNA#U0?
The R5F100GDGNA#U0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance over −20°C to +85°C, and the RL78 core's 3-stage pipeline enables consistent throughput even under dynamic voltage scaling. This makes the R5F100GDGNA#U0 suitable for real-time control loops requiring sub-100 ns timing resolution.
Does the R5F100GDGNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GDGNA#U0 supports full in-system programming via its on-chip debug interface and includes flash shield window and boot swap functions. These features allow authenticated firmware updates in the field without erasing the entire flash, and prevent unauthorized access to protected memory regions - essential for maintaining integrity in deployed industrial equipment.
How does the R5F100GDGNA#U0 manage ultra-low-power operation in battery-powered applications?
The R5F100GDGNA#U0 achieves 0.57 μA STOP mode current with RTC and LVD active, and 66 μA/MHz active-mode efficiency. It supports multiple low-power states (HALT, STOP, SNOOZE), programmable LVD thresholds (14 levels), and automatic wake-up from RTC alarm or external interrupt - enabling multi-year operation on coin-cell batteries in wireless sensor endpoints.
What analog capabilities does the R5F100GDGNA#U0 provide for sensor interfacing?
The R5F100GDGNA#U0 integrates a 10-bit ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. It supports simultaneous sampling and conversion with programmable sample-and-hold timing, making it capable of directly digitizing signals from thermistors, strain gauges, and current-loop transmitters without external signal conditioning circuitry.
Is the R5F100GDGNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100GAANA#U0, R5F100GGANA#U0) share identical pinouts and electrical characteristics. This allows drop-in replacement across memory configurations (16–512 KB flash) and data flash options (4–8 KB), simplifying design scalability and inventory management for industrial product families.
