Product details
Overview
R5F100EEGNA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 48 KB flash, 4 KB data flash, and 3 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz for low-power industrial control, sensor nodes, and appliance HMI applications.
For engineers reviewing the R5F100EEGNA#20 datasheet, R5F100EEGNA#20 pinout, R5F100EEGNA#20 application, or R5F100EEGNA#20 equivalent, key selection considerations include its 40-pin HWQFN-0.5mm package, integrated RTC + LVD, 10-bit 26-channel ADC, and support for SNOOZE mode ultra-low-power operation (0.57 μA).
Technical Context
The R5F100EEGNA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 10-bit ADC with internal 1.45 V reference and temperature sensor, plus dual serial interfaces including UART/LIN and I²C.
Its power architecture supports HALT, STOP, and SNOOZE modes, with on-chip POR and 14-level LVD for robust reset management. The device includes a 12-bit interval timer, calendar-capable RTC, and watchdog timer driven by a dedicated low-speed oscillator.

FAQ
What is the operating voltage range for the R5F100EEGNA#20?
The R5F100EEGNA#20 operates from 1.6 V to 5.5 V, enabling direct compatibility with single-cell Li-ion, 3.3 V logic, and 5 V legacy systems. Its on-chip voltage detector (LVD) offers 14 programmable threshold levels to ensure reliable reset behavior across this full range, and the 10-bit ADC maintains specified linearity down to 1.6 V supply.
Does the R5F100EEGNA#20 support LIN bus communication?
Yes, the R5F100EEGNA#20 supports LIN 2.2 communication through its UART peripheral with built-in LIN break detection and sync field generation. No external transceiver is required for basic LIN node functionality, though an external driver is needed for bus-level signaling. The device's ±1.0% oscillator accuracy meets LIN timing tolerance requirements.
How many analog input channels does the R5F100EEGNA#20 provide?
The R5F100EEGNA#20 provides up to 26 analog input channels (ANI0–ANI25) on dedicated pins, with selectable resolution of 8 or 10 bits. It includes internal 1.45 V reference voltage and an on-die temperature sensor usable as a system health monitor - all accessible without external components.
What debug interface does the R5F100EEGNA#20 use?
The R5F100EEGNA#20 uses Renesas' on-chip debug interface with SWD (Serial Wire Debug) support via dedicated pins (e.g., P11 for TOOLRxD). It enables full JTAG-equivalent debugging - including breakpoints, watchpoints, and memory inspection - using standard E2 studio or CS+ IDE with compatible debug probes like E2 Lite.
Is the R5F100EEGNA#20 pin-compatible with other RL78/G13 40-pin variants?
Yes, all RL78/G13 40-pin HWQFN variants - including R5F100EAANA#U0, R5F100EEGNA#20, and R5F100EGGNA#20 - share identical pinout, package dimensions, and thermal pad configuration. This allows drop-in replacement across memory variants without PCB redesign, provided firmware accommodates differing flash/RAM sizes.
