Product details
Overview
R5F101GHANA#W0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (24 channels), RTC, UART/I²C/CSI interfaces, and ultra-low-power HALT/STOP/SNOOZE modes - deployed in battery-powered industrial sensors and motor control modules.
For engineers reviewing the R5F101GHANA#W0 datasheet, R5F101GHANA#W0 pinout, R5F101GHANA#W0 application, or R5F101GHANA#W0 equivalent, key selection criteria include its G-grade industrial temp rating, absence of on-chip data flash, 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package, and support for background data flash programming in compatible variants.
Technical Context
The R5F101GHANA#W0 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 features dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and dedicated low-speed oscillator for watchdog and RTC.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, DMA controller (4 channels), and peripheral function routing enabling flexible I/O assignment. The device lacks data flash but retains full code flash self-programming capability with boot swap and flash shield window functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Low-Power Modes | HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD active); extends battery life in wireless sensor nodes. |
Pinout & Package
Package: 48-pin HWQFN (7 mm × 7 mm, 0.5 mm pitch), moisture-sensitive level 3, RoHS-compliant, thermal pad exposed on underside for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD pins (Pins 1, 48) and four VSS pins (Pins 2, 3, 47, 46) ensure stable core/peripheral rail decoupling. |
| P10–P17, P20–P27, P30–P37, P40–P47 | General-purpose I/O ports | 40 configurable GPIOs with N-ch open-drain option, TTL input buffer, and internal pull-up resistors. |

| P20/ANI0/AVREFP | Analog input / ADC reference positive | Primary ADC channel 0 input; doubles as AVREFP when external reference is used - disables internal 1.45 V reference. |
| P21/ANI1/AVREFM | Analog input / ADC reference negative | ADC channel 1 input; serves as AVREFM for differential measurements or ground reference for single-ended mode. |
| RESET | Active-low reset input | Asynchronous reset pin; accepts external push-button or supervisor IC assertion; internal pull-up enabled by default. |
| CLKP/CLKM | Crystal oscillator inputs | Supports 32.768 kHz crystal for RTC; CLKP (Pin 41) and CLKM (Pin 42) require external load capacitors (12.5 pF typical). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.57 μA in STOP mode with RTC + LVD active - enables >10-year battery life in metering applications. |
| Hardware multiplier/divider | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations accelerate PID control and filtering. |
| Peripheral function routing | Flexible mapping of UART, I²C, CSI, and timer outputs to multiple pins - simplifies PCB layout and avoids signal congestion. |
| On-chip RTC with calendar | 99-year calendar, alarm interrupt, and auto-correction - eliminates need for external real-time clock IC in HVAC controllers. |
| Watchdog timer | Dedicated low-speed on-chip oscillator ensures reliable timeout even during main clock failure - critical for safety-critical firmware recovery. |
| Background data flash rewrite | Not applicable - R5F101x series omits data flash; code flash self-programming remains available with BGO disabled. |

The R5F101GHANA#W0 operates up to 32 MHz and delivers 41 DMIPS (Dhrystone 2.1). This performance level supports real-time control loops, communication stack processing, and sensor data aggregation without external acceleration. Its 3-stage pipeline RL78 core ensures consistent instruction timing critical for deterministic embedded applications.
Does the R5F101GHANA#W0 include on-chip data flash memory?
No, the R5F101GHANA#W0 does not include on-chip data flash memory. The '101' in the part number explicitly denotes absence of data flash per Renesas' naming convention. Code flash (128 KB) supports self-programming, but non-volatile parameter storage requires external EEPROM or FRAM if needed in the R5F101GHANA#W0 design.
What package type and dimensions does the R5F101GHANA#W0 use?
The R5F101GHANA#W0 uses a 48-pin HWQFN package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. It complies with JEDEC MO-220 and is moisture-sensitive level 3. The #W0 suffix confirms embossed tape packaging for automated SMT placement.
What is the operating temperature range certified for the R5F101GHANA#W0?
The R5F101GHANA#W0 is rated for -40°C to +105°C ambient operation (G-grade), validated per industrial standards. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where extended thermal resilience is required.
Which serial communication interfaces are integrated into the R5F101GHANA#W0?
The R5F101GHANA#W0 integrates three serial interface types: CSI (Simplified SPI) with up to 8 channels, UART/LIN with up to 4 channels, and I²C/Simplified I²C with up to 10 channels.
