Product details
Overview
R5F100EHGNA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for ultra-low-power industrial sensor nodes, battery-powered metering, and embedded control requiring operation down to 1.6 V and -40°C to +105°C.
For engineers reviewing the R5F100EHGNA#20 datasheet, R5F100EHGNA#20 pinout, R5F100EHGNA#20 application, or R5F100EHGNA#20 equivalent, key selection criteria include its 66 μA/MHz active current, HALT/STOP/SNOOZE low-power modes, on-chip debug support, self-programmable flash with boot swap, and integrated LIN-capable UART for automotive body electronics and industrial HMI interfaces.
Technical Context
The R5F100EHGNA#20 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz RTC mode). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 channel DMA, and serial interfaces: CSI (SPI-compatible), UART/LIN (2–4 channels), and I²C (3–10 channels), all configurable for mixed-voltage I/O (1.8/2.5/3.3 V).

The R5F100EHGNA#20 is rated for industrial operation from -40°C to +105°C (G-grade), validated per JEDEC JESD22-A104 and qualified for continuous use in under-hood automotive modules, factory-floor controllers, and outdoor metering enclosures where thermal stress exceeds consumer-grade limits.
Does the R5F100EHGNA#20 support in-system programming via standard interfaces?
Yes, the R5F100EHGNA#20 supports in-system programming using the on-chip debug interface via SWD or UART, enabling field firmware updates without removing the device. Its self-programming flash with boot swap function ensures safe dual-bank updates - critical for R5F100EHGNA#20 deployments in inaccessible or safety-critical locations.
How many ADC channels does the R5F100EHGNA#20 provide, and what is their resolution?
The R5F100EHGNA#20 provides 26 analog input channels with 10-bit resolution, supporting simultaneous sampling via hardware trigger and selectable conversion clocks. It includes an internal 1.45 V reference and temperature sensor - both accessible through dedicated ANI pins - making the R5F100EHGNA#20 suitable for precision sensor conditioning in environmental monitoring and industrial feedback loops.
Can the R5F100EHGNA#20 operate from a single 1.8 V supply?
Yes, the R5F100EHGNA#20 operates across 1.6 V to 5.5 V, fully functional at 1.8 V. At this voltage, maximum CPU frequency is 16 MHz (per datasheet DC characteristics), and all peripherals - including ADC, RTC, and UART - remain operational, allowing the R5F100EHGNA#20 to serve as the central controller in energy-harvesting or coin-cell-powered designs.
Is the R5F100EHGNA#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., R5F100EGGNA#20, R5F100FHGNA#20) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory scaling or feature adjustment - the R5F100EHGNA#20 can be replaced with higher-flash variants without PCB revision, provided software accommodates memory map differences.
