Product details
Overview
R5F100GDANA#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 R5F100GDANA#U0 datasheet, R5F100GDANA#U0 pinout, R5F100GDANA#U0 application, or R5F100GDANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, industrial-grade -40°C to +105°C operation (G-grade), on-chip debug support, and BGO-capable data flash for background reprogramming in field-upgradable embedded systems.
Technical Context
The R5F100GDANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction timing from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8-channel 16-bit timers, 12-bit interval timer, calendar-mode RTC with alarm/correction, 2–4 channel DMA, UART/LIN, I²C, CSI, 10-bit ADC with internal 1.45 V reference and temperature sensor, and hardware multiplier/divider/MAC - all optimized for deterministic real-time control under strict power budgets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GJANA#U0 | Same 48-pin HWQFN package, 192 KB flash, 8 KB data flash, 16 KB RAM - higher memory density with identical peripherals and power profile. | Suitable where larger firmware image size or extended data logging buffer is required without changing PCB layout. | Select when future firmware growth or additional feature sets (e.g., OTA update partitioning) demand >128 KB code space. |
| R5F101GDANA#U0 | Same pinout and package but lacks data flash memory (0 KB); retains full code flash (128 KB), RAM (12 KB), and peripheral set. | Applicable in cost-sensitive, fixed-function designs where field reprogramming of non-volatile configuration data is unnecessary. | Choose to reduce BOM cost by ~12% when data flash usage (e.g., calibration storage, user settings) is handled externally or omitted. |
Compared with R5F100GDANA#U0, R5F100GJANA#U0 offers scalable firmware headroom while maintaining identical power, timing, and interface behavior; R5F101GDANA#U0 removes data flash to lower unit cost but requires external NV storage for runtime configuration persistence.

The R5F100GDANA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and instruction mix optimization, enabling real-time execution of control algorithms and communication stacks without external acceleration.
Does the R5F100GDANA#U0 support background data flash programming during normal code execution?
Yes, the R5F100GDANA#U0 supports Background Operation (BGO) for data flash memory. This allows the MCU to execute instructions from program memory while simultaneously rewriting data flash - essential for reliable over-the-air firmware updates and runtime parameter storage without system interruption.
What is the operating temperature range specified for the R5F100GDANA#U0, and how is it indicated in the part number?
The R5F100GDANA#U0 is rated for -40°C to +105°C, denoted by the 'G' in its part number (R5F100GDANA#U0). This industrial-grade qualification ensures reliable operation in under-hood automotive environments, factory automation equipment, and outdoor metering enclosures.
How many analog input channels does the R5F100GDANA#U0 support, and what is the ADC resolution?
The R5F100GDANA#U0 features a 10-bit successive-approximation ADC with up to 26 analog input channels. Eight are dedicated (ANI0–ANI7 on P20–P27), and one shared channel (ANI18) is available on P147 - providing flexible sensor connectivity for multi-parameter monitoring systems.
Is an external crystal required for real-time clock functionality in the R5F100GDANA#U0?
No, the R5F100GDANA#U0 includes an integrated real-time clock (RTC) that can operate using either an external 32.768 kHz crystal (connected to CLKP/CLKM) or the internal low-speed oscillator. The RTC provides calendar mode (99-year range), alarm, and automatic clock correction - eliminating mandatory external components for timekeeping.
