Product details
Overview
R5F100GHANA#20 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 and smart metering interfaces.
For engineers reviewing the R5F100GHANA#20 datasheet, R5F100GHANA#20 pinout, R5F100GHANA#20 application, or R5F100GHANA#20 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm pitch 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 R5F100GHANA#20 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-channel 16-bit timers, 3-channel I²C/Simplified I²C, 2–4 UART/LIN interfaces, 2–8 CSI/SPI channels, DMA controller (4 channels), 16×16/32÷32 multiplier/divider, and BCD correction circuit - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GHAFB#V0 | LQFP-48 (7×7 mm, 0.5 mm pitch) vs. HWQFN-48; identical memory/peripherals; same G-grade temp rating | Preferred where manual soldering or test probing is required; larger pad pitch eases rework | Select for prototyping or low-volume production where QFN assembly infrastructure is unavailable |
| R5F101GHANA#20 | No data flash (0 KB); same 128 KB code flash, 12 KB RAM, and peripheral set; otherwise pin-compatible | Suitable for cost-sensitive applications where firmware updates occur only via external loader or factory programming | Choose when data flash persistence is unnecessary and BOM cost reduction is critical |
Compared with R5F100GHANA#20, R5F100GHAFB#V0 offers identical functionality in a more manufacturable LQFP package but increases PCB area by ~35%; R5F101GHANA#20 removes data flash to reduce die size and cost, eliminating background rewriting capability but retaining full code execution and real-time control features.

FAQ
What is the maximum operating frequency and associated DMIPS rating of the R5F100GHANA#20?
The R5F100GHANA#20 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under typical conditions (VDD = 3.3 V, TA = 25°C). The high-speed on-chip oscillator supports this frequency without external components, and ±1.0% accuracy ensures reliable timing for real-time tasks in the R5F100GHANA#20.
Does the R5F100GHANA#20 support background data flash rewriting while executing application code?
Yes, the R5F100GHANA#20 supports background operation (BGO) for data flash rewriting: instructions can be fetched and executed from program memory while simultaneously erasing or programming the 8 KB data flash. This capability enables seamless over-the-air firmware updates and parameter storage without halting real-time functions - a core feature confirmed in the R5F100GHANA#20 datasheet section 1.1.
What is the industrial temperature grade of the R5F100GHANA#20, and how is it indicated in the part number?
The R5F100GHANA#20 is rated for −40°C to +105°C operation, designated by the "G" in its part number (R5F100G…), per Renesas' RL78/G13 ordering convention. This G-grade qualification meets industrial environmental requirements and is verified across voltage (1.6–5.5 V) and frequency (up to 32 MHz) ranges - critical for deployment in harsh environments where the R5F100GHANA#20 is commonly used.
How many analog input channels does the R5F100GHANA#20 support, and what is the ADC resolution?
The R5F100GHANA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable across multiple I/O ports. It includes an internal 1.45 V reference voltage and supports operation across the full 1.6–5.5 V supply range - enabling accurate sensor measurements without external references in designs using the R5F100GHANA#20.
Is the R5F100GHANA#20 pin-compatible with other RL78/G13 variants in the same package footprint?
Yes, the R5F100GHANA#20 is pin-compatible with all other RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100FHANA#20, R5F100JHANA#20), sharing identical pin functions and electrical characteristics. Differences lie solely in memory configuration and feature enablement - allowing scalable design reuse across performance tiers while maintaining the same R5F100GHANA#20 PCB layout.
