Product details
Overview
R5F100GCDNA#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 systems.
For engineers reviewing the R5F100GCDNA#U0 datasheet, R5F100GCDNA#U0 pinout, R5F100GCDNA#U0 application, or R5F100GCDNA#U0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip debug support, self-programming flash with boot swap, and hardware DMA for low-CPU-overhead peripheral data movement.
Technical Context
The R5F100GCDNA#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 and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling deterministic real-time response in mixed-signal embedded applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCGNA#U0 | Same 48-pin HWQFN package, identical memory (128 KB/8 KB/12 KB), but rated for −40°C to +85°C (D-grade) | Targeted for commercial/industrial environments without extended temperature requirement | Select when full −40°C to +105°C operation is not required; lower cost and wider distributor availability |
| R5F100GKAFB#V0 | LQFP-48 (7 × 7 mm, 0.5 mm pitch), same memory and peripherals, but requires different PCB layout and thermal pad handling | Suitable for prototyping or designs where QFN rework is constrained and hand-soldering is preferred | Choose for easier assembly, test, or legacy board compatibility - no functional change, only package migration |
Compared with R5F100GCDNA#U0, R5F100GCGNA#U0 trades extended temperature rating for broader supply chain access, while R5F100GKAFB#V0 retains full functionality but shifts to LQFP for simplified manufacturing - both preserve identical firmware and peripheral configuration.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100GCDNA#U0?
The R5F100GCDNA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency under benchmark conditions defined in Renesas documentation (R01DS0131EJ0380), and is achievable using the high-accuracy on-chip oscillator without external crystal.
Does the R5F100GCDNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GCDNA#U0 supports full in-system programming via on-chip debug interface and includes flash security features: block erase prohibition, boot swap function, and flash shield window. These capabilities allow authenticated, field-upgradable firmware with protection against unauthorized modification - critical for deployed industrial devices.
What are the low-power modes supported by the R5F100GCDNA#U0, and what is the lowest current consumption achievable?
The R5F100GCDNA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - verified across the full −40°C to +105°C industrial temperature range. This enables multi-year battery life in intermittently active sensor applications without compromising timekeeping integrity.
How many analog input channels does the R5F100GCDNA#U0 ADC support, and what reference options are available?
The R5F100GCDNA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference inputs (AVREFP/AVREFM), internal 1.45 V reference, and VDD as reference - all selectable per channel. The internal reference is factory-trimmed and usable in HS (high-speed main) mode only.
Is the R5F100GCDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GCDNA#U0 shares identical pinout and electrical characteristics with all 48-pin HWQFN RL78/G13 variants (e.g., R5F100GCGNA#U0, R5F100GEANA#U0), differing only in flash/RAM sizing and temperature grade. Firmware and PCB layout remain interchangeable across this package group - simplifying design reuse and qualification.
