Product details
Overview
R5F100GHANA#W0 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 (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GHANA#W0 datasheet, R5F100GHANA#W0 pinout, R5F100GHANA#W0 application, or R5F100GHANA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, industrial-grade −40°C to +105°C operation (G-grade), on-chip data flash rewrite endurance (1M cycles), and support for background operation during flash programming.
Technical Context
The R5F100GHANA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz) and 1 MB address space. It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog/RTC.
Peripherals include 8-channel 16-bit timers, 1-channel 12-bit interval timer, calendar RTC with alarm/correction, 2–4 DMA channels, and multi-protocol serial interfaces - CSI (SPI-like), UART/LIN, and I²C - all configurable across 48 I/O pins with N-ch open-drain, TTL input, and internal pull-up options.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GHAFB#V0 | LQFP-48 (7 × 7 mm, 0.5 mm pitch), same memory/peripherals, but tray packaging and different thermal profile | Better suited for reflow-soldered PCBs with manual inspection access; less compact than HWQFN | Select when board assembly process favors LQFP handling or thermal dissipation requirements exceed HWQFN limits |
| R5F101GHANA#W0 | Same package and pinout, but no data flash (0 KB); reduced RAM (8 KB); identical core/peripherals | Applicable where firmware-only storage suffices and data logging is handled externally | Choose when cost reduction is prioritized and on-chip nonvolatile data storage is unnecessary |
Compared with R5F100GHAFB#V0 and R5F101GHANA#W0, the R5F100GHANA#W0 uniquely balances ultra-compact HWQFN packaging, industrial temperature range, and integrated 8 KB data flash - making it optimal for space-constrained, battery-backed, field-upgradable embedded systems where data retention and layout density are critical.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GHANA#W0?
The R5F100GHANA#W0 operates at up to 32 MHz with a measured performance of 41 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and −40°C to +105°C, eliminating need for external crystal in many timing-critical applications. This frequency enables real-time control loops with sub-μs jitter while sustaining ultra-low active current (66 μA/MHz).
Does the R5F100GHANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100GHANA#W0 supports full in-system programming via its on-chip debug interface and self-programming capability. It includes boot swap functionality and flash shield window protection to prevent unauthorized access during firmware updates. The 8 KB data flash supports background operation (BGO), allowing uninterrupted application execution while writing calibration data or logs - essential for secure, field-deployable R5F100GHANA#W0 implementations.
What analog features does the R5F100GHANA#W0 provide for sensor interfacing?
The R5F100GHANA#W0 integrates a 10-bit ADC with up to 26 input channels, selectable internal 1.45 V reference voltage, and an on-die temperature sensor. It supports simultaneous sampling across multiple channels and includes hardware averaging to improve SNR. These features allow direct connection of resistive, capacitive, or thermistor-based sensors without external signal conditioning - a key enabler for compact, low-BOM-cost R5F100GHANA#W0 sensor nodes.
How does the R5F100GHANA#W0 achieve ultra-low power consumption in battery-powered applications?
The R5F100GHANA#W0 achieves ultra-low power via multiple hardware-optimized modes: HALT (1.2 μA), STOP (0.57 μA with RTC + LVD active), and SNOOZE (selective peripheral wake-up). Its 1.6–5.5 V operation range accommodates declining battery voltages, and the on-chip LVD provides 14 programmable thresholds for graceful shutdown. These capabilities extend operational lifetime in coin-cell or Li-SOCl₂ powered R5F100GHANA#W0 deployments beyond 10 years.
Is the R5F100GHANA#W0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the HWQFN-48 package - including R5F100GHANA#W0, R5F100GHAFB#V0, and R5F101GHANA#W0 - share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory scaling (flash/data flash/RAM) or feature trimming (e.g., removing data flash), provided firmware is reconfigured to match peripheral availability - a verified design flexibility point for R5F100GHANA#W0 migration paths.
