Product details
Overview
R5F100EGGNA#20 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EGGNA#20 datasheet, R5F100EGGNA#20 pinout, R5F100EGGNA#20 application, or R5F100EGGNA#20 equivalent, this page delivers verified specifications, package mapping, real-world use cases, and validated alternative options aligned to Renesas' official RL78/G13 documentation (R01DS0131EJ0380 Rev.3.80).
Technical Context
The R5F100EGGNA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed on-chip oscillator.
Peripherals include an 8/10-bit A/D converter with up to 26 analog inputs and internal 1.45 V reference, 2–4 channel DMA controller, 16-bit timer (up to 16 channels), and serial interfaces: CSI (SPI-compatible), UART/LIN (2–4 channels), and I²C/Simplified I²C (3–10 channels).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EGDNA#20 | Same core, flash, RAM, and package; D-grade (−40°C to +85°C) instead of G-grade; LVD levels limited to 12 vs. 14. | Targeted at consumer-grade HVAC or appliance control where extended temperature range is not required. | Select when industrial temperature qualification is unnecessary and cost optimization is prioritized. |
| R5F101EGGNA#20 | Identical package and pinout; lacks data flash memory (0 KB vs. 4 KB); same 64 KB code flash and 4 KB RAM. | Suitable for fixed-function devices requiring no field-upgradable parameters or logging - e.g., simple motor drivers. | Choose when data retention between power cycles is handled externally or not needed; reduces BOM cost by ~12%. |
Compared with R5F100EGGNA#20, R5F100EGDNA#20 trades industrial temperature margin for lower cost, while R5F101EGGNA#20 removes data flash to simplify firmware architecture - both require no PCB changes but differ in functional scope and qualification coverage.

The R5F100EGGNA#20 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, active current consumption is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz under typical conditions. This value is measured at VDD = 3.0 V and TA = 25°C per R01DS0131EJ0380 Rev.3.80.
Does the R5F100EGGNA#20 support in-system programming and secure firmware updates?
Yes, the R5F100EGGNA#20 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to prevent unauthorized access to protected memory regions. Its self-programming capability with boot swap ensures atomic firmware updates without risk of corruption during power loss.
How many analog input channels does the R5F100EGGNA#20 provide, and what is the ADC resolution?
The R5F100EGGNA#20 provides up to 26 analog input channels with an 8/10-bit successive approximation register (SAR) ADC. Resolution is selectable per channel; 10-bit mode delivers 1 LSB = VDD/1024, supporting precision measurement across its 1.6–5.5 V operating range.
What packaging and thermal characteristics define the R5F100EGGNA#20?
The R5F100EGGNA#20 uses a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch) with an exposed thermal pad. Its θJA is 42°C/W (JEDEC JESD51-7), enabling reliable operation at full 32 MHz in ambient temperatures up to +105°C when properly mounted on a 2-layer PCB with ≥2 cm² copper pour under the pad.
Is the R5F100EGGNA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100EAANA#20, R5F100EHGNA#20) share identical pinouts and electrical characteristics. Pin compatibility extends across flash sizes (16–128 KB), RAM configurations (2–12 KB), and data flash presence - enabling scalable design reuse.
