Product details
Overview
R5F100GCGNA#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 battery-powered industrial sensor nodes.
For engineers reviewing the R5F100GCGNA#U0 datasheet, R5F100GCGNA#U0 pinout, R5F100GCGNA#U0 application, or R5F100GCGNA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, industrial-grade −40°C to +105°C operation (G-grade), on-chip debug support, and background data flash rewriting capability for firmware updates without halting execution.
Technical Context
The R5F100GCGNA#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-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× 16-bit timers, 1× 12-bit interval timer, 1× calendar-capable RTC with alarm/correction, 2–4-channel DMA, UART/LIN, CSI, I²C, and 16-bit multiplier/divider/MAC - all designed for deterministic real-time control in resource-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic interrupt latency and compact code density for cost-sensitive control applications. |
| Max Clock Speed | 32 MHz (41 DMIPS); delivers sufficient throughput for motor control, sensor fusion, and protocol stack handling in edge devices. |
| Memory | 128 KB code flash + 8 KB data flash + 12 KB RAM; supports secure block erase prohibition and background data flash rewriting (BGO) for robust field updates. |
| Power Modes | HALT (66 μA/MHz), STOP (0.57 μA w/ RTC+LVD active); enables multi-year battery life in metering and IoT endpoint designs. |
| Analog Peripherals | 10-bit ADC with 26 input channels, internal 1.45 V reference, and temperature sensor; eliminates need for external references in environmental monitoring. |
| Operating Temp | −40°C to +105°C (G-grade); qualified for under-hood automotive modules, industrial PLC I/O, and high-ambient factory automation. |

Pinout & Package
Package: 48-pin HWQFN (7 mm × 7 mm, 0.5 mm pitch), exposed thermal pad, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD pins (Pins 1, 48) and multiple VSS (Pins 2, 24, 25, 47) ensure stable core/peripheral rail decoupling and low-noise analog operation. |
| P00–P07 | General-purpose I/O with N-ch open drain | Configurable as TTL input, pull-up enabled, or 6 V-tolerant outputs; supports direct interface to 1.8/2.5/3.3 V logic without level shifters. |
| P10–P17 | Multi-function I/O (SCK00/SI00/SO00, UART, I²C) | Shared serial interfaces enable flexible peripheral mapping - e.g., P10/P11 serve as SCK00/RxD0/SDA00 for concurrent SPI and I²C use. |
| ANI0–ANI25 | Analog input channels | 26-channel ADC inputs distributed across ports; ANI0/ANI1 double as AVREFP/AVREFM for precision ratiometric measurements. |
| RTCCLK, X1, X2 | Real-time clock oscillator terminals | Supports external 32.768 kHz crystal (X1/X2) or RC oscillator; RTC retains calendar/time during STOP mode with LVD supervision. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.57 μA with RTC and LVD active - enables decade-scale battery operation in smart utility meters and wireless sensors. |
| Background Data Flash Rewrite (BGO) | Execute code from flash while erasing/writing data flash; critical for seamless OTA firmware updates without system interruption. |
| On-chip debug interface | Fully integrated with E1/E20 emulators via single-pin SWD; eliminates need for external debug headers in production PCBs. |
| Hardware multiplier/divider | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations accelerate PID control, filtering, and sensor calibration math. |
| Multi-voltage I/O | I/O pins tolerate 1.8 V, 2.5 V, and 3.3 V logic levels; simplifies mixed-voltage board design and reduces BOM count for level-shifting components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGNA#U0 | Same 48-pin HWQFN package, but 16 KB flash / 4 KB data flash / 2 KB RAM; lower memory capacity and reduced peripheral count (e.g., fewer timers, UARTs). | Suitable for simpler control tasks like basic LED drivers or small appliance remotes where full 128 KB flash is unnecessary. | Select when cost sensitivity outweighs future firmware scalability needs; verify ADC channel count and timer availability match design requirements. |
| R5F101GCGNA#U0 | Identical pinout and package, but no data flash memory; retains same 128 KB code flash and 12 KB RAM; lacks BGO and flash shield window function. | Appropriate for fixed-function devices requiring only code updates (not runtime parameter storage), such as legacy industrial controllers with static configuration. | Choose when data retention during power loss is handled externally; avoid if field-upgradable calibration tables or user settings are required. |
Compared with R5F100GCGNA#U0, R5F100GAGNA#U0 trades memory and peripherals for lower unit cost, while R5F101GCGNA#U0 removes data flash to simplify security management - both retain identical packaging and industrial temperature rating but constrain firmware flexibility differently.

FAQ
What is the maximum operating frequency and associated performance of the R5F100GCGNA#U0?
The R5F100GCGNA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs per instruction at full speed down to 30.5 μs in ultra-low-power 32.768 kHz mode - enabling precise trade-offs between responsiveness and energy consumption in the R5F100GCGNA#U0.
Does the R5F100GCGNA#U0 support in-system programming and secure firmware updates?
Yes, the R5F100GCGNA#U0 supports self-programming of both code and data flash memory with features including boot swap functionality and flash shield window protection. It also provides background operation (BGO) for data flash writes, allowing program execution to continue uninterrupted - essential for secure, fail-safe firmware updates in deployed R5F100GCGNA#U0 systems.
What are the key low-power capabilities of the R5F100GCGNA#U0 relevant to battery-powered designs?
The R5F100GCGNA#U0 offers HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode for selective peripheral wake-up. Its 1.6 V minimum supply voltage and integrated voltage detector (LVD) with 14 programmable thresholds enable reliable brown-out detection and graceful shutdown - collectively extending operational lifetime in coin-cell or AA-powered R5F100GCGNA#U0 applications.
How does the R5F100GCGNA#U0 handle analog signal acquisition in noisy industrial environments?
The R5F100GCGNA#U0 integrates a 10-bit ADC with 26 input channels, selectable internal 1.45 V reference, and dedicated AVREFP/AVREFM pins for ratiometric measurement stability. Its I/O structure supports N-ch open-drain outputs and on-chip pull-ups, reducing susceptibility to noise coupling - making the R5F100GCGNA#U0 well-suited for direct sensor interfacing in electrically harsh settings.
Is the R5F100GCGNA#U0 pin-compatible with other RL78/G13 variants, and what package options exist?
The R5F100GCGNA#U0 uses a 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package with exposed thermal pad. It shares pinout compatibility within the 48-pin HWQFN subgroup of RL78/G13 (e.g., R5F100GAxxx#U0, R5F100GGxxx#U0), but is not pin-compatible with LQFP or WFLGA variants. Always verify pin mapping against the specific variant's datasheet before board reuse - the R5F100GCGNA#U0's footprint is optimized for thermal performance and high-density layouts.
