Product details
Overview
R5F101GLDFB#V0 from Renesas is a 48-pin LFQFP, 0.5-mm pitch, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU 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). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock-used in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101GLDFB#V0 datasheet, R5F101GLDFB#V0 pinout, R5F101GLDFB#V0 application, or R5F101GLDFB#V0 equivalent, key selection criteria include its G-grade temperature rating, absence of on-chip data flash (R5F101x series), LFQFP-48 package compatibility, and support for SNOOZE mode wake-up via analog comparator or serial interface.
Technical Context
The R5F101GLDFB#V0 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). Its memory map spans 1 MB address space, with dedicated SFR regions for peripheral control and DMA-triggered transfers requiring only 2 clocks between SFR and RAM.
Power management includes HALT, STOP, and SNOOZE modes; the latter enables background serial communication or timer operation while CPU remains halted. The on-chip high-accuracy oscillator (±1.0% over −20°C to +85°C) supports 10 selectable frequencies from 1–32 MHz without external crystal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing for real-time control loops. |
| Flash Memory | 128 KB code flash (1-KB block size); supports self-programming with boot swap and flash shield window. |
| Data Flash | Not integrated (R5F101x series); requires external EEPROM or FRAM for nonvolatile parameter storage. |
| RAM | 12 KB on-chip RAM; includes dedicated areas for flash library use (start address FF300H). |
| ADC | 10-bit resolution, 26-channel SAR ADC with internal 1.45 V reference and temperature sensor. |
| Operating Voltage | 1.6 V to 5.5 V single supply; supports direct connection to Li-ion, 3.3 V, or 5 V rails without level-shifting. |

| Low-Power Modes | HALT (66 μA/MHz), STOP (0.57 μA), SNOOZE (peripheral-active CPU-halted); extends battery life in wireless sensors. |
Pinout & Package
Package: 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | Serial Clock Input/Output | Shared SPI clock (SCK00) and I²C clock (SCL00); enables dual-interface peripheral sharing on one pin. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | Serial Data Input/Receive | Multi-function pin supporting SPI input (SI00), UART receive (RxD0), debug tool RX (TOOLRxD), and I²C data (SDA00). |

| P20/ANI0/AVREFP | Analog Input / ADC Reference Positive | Primary ADC channel 0 input and positive reference voltage source; allows ratiometric sensing with external divider. |
| P21/ANI1/AVREFM | Analog Input / ADC Reference Negative | ADC channel 1 input and negative reference; enables differential measurement or external reference biasing. |
| P40/INTP0/RTCCLK | Interrupt Input / RTC Clock Source | Accepts external interrupt request or 32.768 kHz crystal for calendar-mode RTC; critical for time-stamped logging. |
| VDD, VSS | Power Supply / Ground | Dual VDD/VSS pairs (pins 1/2, 47/48) reduce noise coupling and improve EMI robustness in mixed-signal layouts. |
| RESET | Active-Low Reset Input | Asynchronous reset with internal pull-up; compatible with pushbutton, supervisor IC, or microcontroller-initiated system reset. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power SNOOZE mode | Enables UART or timer operation while CPU sleeps-reduces average current in periodic telemetry systems by >90%. |
| On-chip high-accuracy oscillator | ±1.0% frequency stability (1.8–5.5 V, −20°C to +85°C); eliminates external crystal for cost-sensitive industrial HMI designs. |
| Background data flash rewrite | Not applicable-R5F101GLDFB#V0 lacks on-chip data flash; design must allocate external nonvolatile memory for field-updatable parameters. |
| Real-time clock with calendar | 99-year calendar, alarm, and clock correction; supports timestamped event logging in energy meters and building automation. |
| Multi-protocol serial interface | Configurable CSI (SPI-like), UART (LIN-capable), and I²C on shared pins-reduces PCB routing complexity in sensor fusion modules. |
| Hardware multiplier/divider | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations accelerate PID control and sensor linearization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLDFB#V0 | Includes 8 KB on-chip data flash; same flash/RAM/package but adds nonvolatile parameter storage capability. | Suitable where field-upgradable calibration tables or configuration profiles are required without external memory. | Select when persistent parameter storage is mandatory and board space prohibits external EEPROM. |
| RL78/G14 R5F11GLFD#V0 | Enhanced RL78/G14 variant with larger 256 KB flash, 32 KB RAM, and additional peripherals (USB, CAN). | Targeted at more complex HMI or gateway applications requiring protocol bridging or higher compute throughput. | Choose for future-proofing or when scaling functionality beyond G13 capabilities-requires PCB layout change due to 64-pin LQFP package. |
Compared with R5F100GLDFB#V0, the R5F101GLDFB#V0 reduces BOM cost by eliminating data flash but increases system design complexity for nonvolatile storage; versus RL78/G14, it trades peripheral richness and memory headroom for lower power and smaller footprint in resource-constrained edge nodes.

FAQ
Does R5F101GLDFB#V0 include on-chip data flash memory?
No, R5F101GLDFB#V0 does not integrate data flash memory. The "101" in the part number explicitly denotes absence of on-chip data flash per Renesas' RL78/G13 naming convention. Designs requiring nonvolatile parameter storage must use external EEPROM, FRAM, or serial flash. R5F100GLDFB#V0 is the functionally identical variant with 8 KB data flash.
What is the maximum operating frequency and corresponding current consumption of R5F101GLDFB#V0?
R5F101GLDFB#V0 operates up to 32 MHz using the on-chip high-speed oscillator. At this frequency and 3.3 V supply, active-mode current is 66 μA/MHz (2.11 mA typical). In STOP mode with RTC and LVD enabled, current drops to 0.57 μA-verified across the full −40°C to +105°C industrial temperature range.
Which development tools support R5F101GLDFB#V0 firmware debugging and programming?
R5F101GLDFB#V0 is fully supported by Renesas E2 studio IDE, CS+ (formerly CubeSuite+), and the E2 emulator Lite. Debugging uses the standard 10-pin JTAG/SWJ interface (pins P15–P17, RESET, VDD, VSS); no external debug probe is needed for basic flash programming and breakpoint debugging.
Can R5F101GLDFB#V0 drive standard 5 V logic peripherals directly?
Yes-R5F101GLDFB#V0 GPIOs support 5 V-tolerant inputs and can source/sink up to 20 mA per pin (with total package limit of 100 mA). When powered from 5 V VDD, outputs swing rail-to-rail; when powered from 3.3 V, outputs remain compatible with 5 V CMOS inputs due to TTL-level recognition thresholds.
Is the real-time clock (RTC) in R5F101GLDFB#V0 battery-backed and capable of calendar operation?
Yes, the R5F101GLDFB#V0 RTC supports full calendar functionality (year/month/day/hour/minute/second), alarm, and clock correction. It operates from VDD or an optional backup battery on the VBAT pin. Calendar accuracy is maintained in STOP mode with only RTC and LVD active-consuming just 0.57 μA.
