Product details
Overview
R5F100GHDNA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial sensor nodes, motor control interfaces, and battery-powered HMI panels.
For engineers reviewing the R5F100GHDNA#U0 datasheet, R5F100GHDNA#U0 pinout, R5F100GHDNA#U0 application, or R5F100GHDNA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm pitch package, integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, and support for LIN-bus UART and hardware DMA across 4 channels - all operating from 1.6–5.5 V over –40°C to +105°C.
Technical Context
The R5F100GHDNA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates dual-clock domains: a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and a dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI/SPI channels, and background operation (BGO) for data flash rewriting while executing code - critical for firmware-over-the-air updates in field-deployed devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GHDFB#V0 | Same core, memory, and peripherals; differs in package (48-pin LFQFP, 0.5 mm pitch) and temperature grade (D-grade: –40°C to +85°C) | Suitable for cost-sensitive industrial PCBs where QFN thermal performance is not required and reflow compatibility with larger pitch is preferred | Select when standard LQFP assembly infrastructure exists and extended temperature is not needed |
| R5F101GHDNA#U0 | Identical package and pinout but lacks data flash (0 KB); retains same 128 KB code flash, 12 KB RAM, and peripheral set | Applicable where field firmware updates are handled externally or via external EEPROM, reducing security and wear-leveling requirements | Choose when data logging or parameter storage is implemented off-chip to lower unit cost |
Compared with R5F100GHDNA#U0, R5F100GHDFB#V0 trades HWQFN thermal efficiency for easier hand-soldering and broader reflow tolerance, while R5F101GHDNA#U0 removes data flash to reduce die size and cost - both retain full functional compatibility except for non-volatile data storage capability.

FAQ
What is the maximum operating frequency of the R5F100GHDNA#U0?
The R5F100GHDNA#U0 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over –20°C to +85°C). External crystal or clock input can also drive the system up to 20 MHz, and the CPU executes instructions in as little as 0.03125 μs at full speed. The R5F100GHDNA#U0 maintains full peripheral functionality across this range.
Does the R5F100GHDNA#U0 include an integrated temperature sensor?
Yes, the R5F100GHDNA#U0 includes an on-chip temperature sensor usable with the 10-bit ADC. It is accessible only in HS (high-speed main) mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage. This eliminates the need for external thermal monitoring components in ambient temperature-aware applications.
What debug interface does the R5F100GHDNA#U0 support?
The R5F100GHDNA#U0 supports Renesas' Full-spec on-chip debug interface via SWD (Serial Wire Debug), enabling breakpoints, watchpoints, real-time variable inspection, and flash programming without external JTAG hardware. It requires only two pins (SWCLK and SWDIO) and is compatible with E2 studio and CS+ development environments.
Can the R5F100GHDNA#U0 operate from a single 1.8 V supply?
Yes, the R5F100GHDNA#U0 operates across 1.6 V to 5.5 V, making it fully compatible with 1.8 V systems. At 1.8 V, it supports up to 16 MHz operation with full peripheral functionality including ADC, timers, and communication interfaces - ideal for low-voltage battery-powered designs.
Is the R5F100GHDNA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100GxANA#U0 series) share identical pinouts and electrical characteristics. This allows direct substitution between memory variants (e.g., R5F100GFDNA#U0 → R5F100GHDNA#U0) without PCB changes, provided software accommodates differences in flash/RAM size and data flash presence.
