Product details
Overview
R5F101GCANA#W0 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces including UART, I²C, and CSI. It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GCANA#W0 datasheet, R5F101GCANA#W0 pinout, R5F101GCANA#W0 application, or R5F101GCANA#W0 equivalent, key selection criteria include its 48-pin HWQFN package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode for low-power sensor wake-up.
Technical Context
The R5F101GCANA#W0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz) and 1 MB address space. It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 DMA channels (2-cycle transfer between SFR and RAM), and multi-protocol serial interfaces: 2–4 UART/LIN, 3–10 I²C/Simplified I²C, and 2–8 CSI (SPI-compatible) channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 32-bit CISC with 3-stage pipeline; enables deterministic timing and efficient code density for embedded control. |
| Max Operating Frequency | 32 MHz (41 DMIPS); delivers real-time responsiveness in motor control and sensor fusion applications. |
| Flash Memory | 128 KB code flash (1 KB block size); supports secure boot, self-programming, and flash shield window protection. |
| Data Flash | None (R5F101x series); eliminates data retention overhead but requires external EEPROM or FRAM for nonvolatile parameter storage. |
| RAM | 12 KB on-chip RAM; sufficient for RTOS stacks, communication buffers, and algorithm working memory. |
| ADC | 10-bit resolution, 26 input channels, internal 1.45 V reference and temperature sensor; enables precision analog monitoring without external components. |
| Low-Power Modes | HALT (0.57 μA), STOP, SNOOZE; extends battery life in intermittent-sensing applications like wireless sensor nodes. |
Pinout & Package
Package: 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch), moisture sensitivity level (MSL) 3, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains support mixed-voltage I/O (1.8/2.5/3.0 V interface capability). |
| P00–P07, P10–P17, P20–P27, P30–P37, P40–P47, P50–P57 | General-purpose I/O ports | Up to 44 programmable I/O pins with N-ch open-drain, TTL input buffer, and on-chip pull-up options. |
| P20/P21 | Analog inputs (AVREFP/AVREFM) | Dedicated reference voltage pins for high-accuracy ADC operation across full VDD range (1.6–5.5 V). |
| P10/P11/P12 | CSI0/SCL0/SDA0 (serial interface) | Configurable as SPI master/slave (CSI), I²C master/slave, or UART; enables flexible peripheral connectivity. |
| P14/P15 | CLKP/CLKM (subsystem clock) | Accepts 32.768 kHz crystal for RTC; enables calendar function and ultra-low-power timekeeping. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power HALT mode | 0.57 μA with RTC and LVD active-enables >10-year battery life in coin-cell-powered IoT endpoints. |
| On-chip debug with boot swap | Enables field firmware updates without external programmer; boot swap ensures fail-safe recovery during OTA upgrades. |
| Background operation (BGO) | Not applicable-R5F101x lacks data flash, so BGO for data flash rewrite is unavailable; program execution continues during code flash erase/write via interrupt masking. |
| Multi-protocol serial interface | Single hardware module supports UART, LIN, I²C, and CSI-reduces PCB footprint and simplifies protocol migration. |
| Temperature sensor + 1.45 V reference | Eliminates need for external calibration components; enables self-compensated sensor readings in environmental monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCANA#W0 | Includes 8 KB data flash; same 128 KB code flash, 12 KB RAM, and identical peripherals. | Preferred where firmware must store calibration data, device configuration, or event logs internally without external memory. | Select when nonvolatile parameter storage is required and cost premium for data flash is acceptable. |
| R5F101GCAFJ#V0 | LQFP-48 (10 × 10 mm, 0.65 mm pitch) instead of HWQFN-48; identical memory and peripheral spec. | Better suited for prototyping or low-volume production where reflow compatibility with standard QFP footprints is prioritized. | Choose for easier hand-soldering, test fixture access, or legacy PCB layout reuse with LQFP pads. |
Compared with R5F100GCANA#W0, the R5F101GCANA#W0 reduces BoM count by eliminating external data storage but requires host MCU or cloud-side parameter management; versus R5F101GCAFJ#V0, it offers superior thermal performance and smaller footprint critical for space-constrained metering modules.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F101GCANA#W0?
The R5F101GCANA#W0 operates at up to 32 MHz with a performance rating of 41 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling real-time processing for motor control, sensor fusion, and communication stack execution without external acceleration.
Does the R5F101GCANA#W0 include on-chip data flash memory?
No, the R5F101GCANA#W0 does not include on-chip data flash memory. As indicated by the "101" in its part number (per Renesas documentation), this variant belongs to the data-flash-less series. Applications requiring nonvolatile parameter storage must use external EEPROM, FRAM, or rely on code flash sectors managed via software wear-leveling.
What package type and pin count does the R5F101GCANA#W0 use?
The R5F101GCANA#W0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch), identified by the "NA" suffix and "#W0" embossed tape packaging code. This compact, thermally efficient package supports automated assembly and is rated for industrial temperature operation (-40°C to +85°C).
Which serial communication protocols are supported by the R5F101GCANA#W0?
The R5F101GCANA#W0 supports UART (with LIN bus compliance), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). These are implemented in shared peripheral modules-e.g., one channel can be configured as UART, I²C master, or CSI slave-providing flexibility in system-level interface allocation.
How does the low-power capability of the R5F101GCANA#W0 compare to typical 32-bit MCUs?
The R5F101GCANA#W0 achieves 66 μA/MHz active current and just 0.57 μA in HALT mode (RTC + LVD active)-significantly lower than most Cortex-M0+/M3 MCUs. This enables multi-year operation on coin cells in sensor nodes, making it especially valuable for battery-powered infrastructure monitoring where maintenance access is limited.
