Product details
Overview
R5F101GCDFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for ultra-low-power industrial control applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F101GCDFB#X0 datasheet, R5F101GCDFB#X0 pinout, R5F101GCDFB#X0 application, or R5F101GCDFB#X0 equivalent, key selection criteria include its 0.57 μA STOP-mode current, 41 DMIPS @ 32 MHz performance, integrated LIN-capable UARTs, and support for background data flash rewriting without CPU stall.
Technical Context
The R5F101GCDFB#X0 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 RTC mode). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and on-chip voltage detector with 14 selectable LVD levels.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, and 2–8× CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in safety-critical control loops. |
| Operating Voltage | 1.6 V to 5.5 V; supports direct battery operation (e.g., 2× AA/AAA) and wide-input industrial power rails. |
| Power Consumption | 66 μA/MHz active; 0.57 μA in STOP mode with RTC + LVD active - extends battery life in metering and sensor nodes. |
| Memory Resources | 96 KB code flash (1 KB blocks), 8 KB data flash (1M rewrite cycles), 8 KB RAM - sufficient for firmware + logging in edge controllers. |
| Analog Peripherals | 10-bit ADC with 26 input channels, internal 1.45 V reference, and integrated temperature sensor - eliminates external references in thermal monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCDFB#X0 | Includes 8 KB data flash; same package, pinout, and peripherals - differs only in data flash presence. | Required where persistent parameter storage (e.g., calibration tables, device IDs) must survive power loss. | Select R5F100GCDFB#X0 if data flash is mandatory; otherwise R5F101GCDFB#X0 reduces cost and flash programming overhead. |
| RL78/G14 R5F11GGEAFB#X0 | Higher performance (45 DMIPS @ 32 MHz), larger memory (128 KB flash, 12 KB RAM), enhanced ADC (12-bit, 32 ch), but larger 64-pin LQFP package. | Used in more complex systems requiring additional peripherals (e.g., USB, CAN) or larger firmware footprints. | Choose R5F11GGEAFB#X0 only when R5F101GCDFB#X0 memory or peripheral limits are exceeded - not a drop-in replacement. |
Compared with R5F100GCDFB#X0, the R5F101GCDFB#X0 removes data flash to lower cost and simplify firmware update logic, while retaining identical code flash size, RAM, and peripheral set - making it ideal for fixed-parameter applications. The RL78/G14 alternative offers higher capability but requires PCB redesign due to different pin count and layout.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F101GCDFB#X0?
The R5F101GCDFB#X0 operates up to 32 MHz with a typical active current of 66 μA/MHz, yielding ~2.1 mA at full speed. Its ultra-low-power design achieves 0.57 μA in STOP mode with RTC and LVD active - verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F101GCDFB#X0 include data flash memory?
No, the R5F101GCDFB#X0 does not include data flash memory. The "101" in the part number explicitly denotes absence of data flash, unlike "100" variants (e.g., R5F100GCDFB#X0) which integrate 8 KB. This simplifies firmware update logic and reduces cost for fixed-parameter applications.
Which communication interfaces are supported by the R5F101GCDFB#X0?
The R5F101GCDFB#X0 supports up to 4× UART/LIN interfaces (with LIN bus compliance), 3–10× I²C/Simplified I²C channels, and 2–8× CSI (SPI-compatible) channels - all accessible via shared pins and software-configurable peripheral multiplexing per the RL78/G13 datasheet Section 1.1.
What is the ADC resolution, channel count, and reference voltage options on the R5F101GCDFB#X0?
The R5F101GCDFB#X0 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference inputs or internal 1.45 V reference (selectable only in HS mode), enabling ratiometric measurements without external precision references.
Is the R5F101GCDFB#X0 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F101GCDFB#X0 is pin-compatible with all 48-pin LFQFP RL78/G13 variants (e.g., R5F100GCDFB#X0, R5F101GCAFB#X0), sharing identical pin functions and electrical characteristics. Differences are limited to internal memory configuration and data flash presence - no PCB changes required for migration within this package group.
