Product details
Overview
R5F101GCDFB#50 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, no data flash, and industrial-grade -40°C to +85°C operation. It integrates 16-bit timer (12 channels), 10-bit ADC (26 channels), UART/SPI/I²C interfaces, RTC, and ultra-low-power HALT/STOP modes for embedded control in metering, sensor nodes, and appliance HMI.
For engineers reviewing the R5F101GCDFB#50 datasheet, R5F101GCDFB#50 pinout, R5F101GCDFB#50 application, or R5F101GCDFB#50 equivalent, key selection criteria include its 96 KB code flash / 8 KB RAM balance, absence of on-chip data flash, LFQFP-48 package with 0.5 mm pitch, and support for 32 MHz max CPU frequency with 41 DMIPS performance at 32 MHz.
Technical Context
The R5F101GCDFB#50 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 banked 8-bit general-purpose registers.
Power management includes on-chip POR, LVD with 14 selectable voltage levels, and multiple low-power modes (HALT, STOP, SNOOZE); real-time clock operates independently with calendar, alarm, and correction functions while consuming only 0.57 μA in RTC+LVD-only mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCDFB#50 | Includes 4 KB data flash; same 96 KB code flash, 8 KB RAM, and LFQFP-48 package | Required where field firmware updates or parameter storage (e.g., calibration tables) must persist across power cycles | Select when non-volatile parameter retention is mandatory; otherwise R5F101GCDFB#50 reduces cost and simplifies flash management |
| R5F101GCDFA#50 | LQFP-48 (0.65 mm pitch) instead of LFQFP-48 (0.5 mm pitch); identical memory and peripherals | Suitable for legacy PCBs designed for standard LQFP footprints or where reflow process favors larger pitch | Choose for compatibility with existing 0.65 mm pitch assembly lines; R5F101GCDFB#50 offers higher I/O density in smaller footprint |
Compared with R5F100GCDFB#50, the R5F101GCDFB#50 removes data flash to lower cost and power, while compared with R5F101GCDFA#50 it enables finer-pitch routing and higher board density via its 0.5 mm LFQFP package-critical for space-constrained HMI and sensor modules.

FAQ
What is the maximum operating frequency and performance rating of the R5F101GCDFB#50?
The R5F101GCDFB#50 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator (±1.0% accuracy) or an external crystal. The RL78 CPU core's 3-stage pipeline enables deterministic execution critical for real-time control loops in the R5F101GCDFB#50.
Does the R5F101GCDFB#50 include on-chip data flash memory?
No, the R5F101GCDFB#50 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100"-series variants like R5F100GCDFB#50 which integrate 4 KB of data flash. The R5F101GCDFB#50 relies on code flash for firmware storage only.
What package type and pin pitch does the R5F101GCDFB#50 use?
The R5F101GCDFB#50 uses a 48-pin LFQFP package with 0.5 mm pin pitch and 7 mm × 7 mm body size. The "FB" suffix in the part number explicitly denotes LFQFP, and "#50" indicates embossed tape packaging. This fine-pitch variant enables higher I/O density than standard LQFP alternatives such as R5F101GCDFA#50.
What are the supported low-power modes and their typical current consumption for the R5F101GCDFB#50?
The R5F101GCDFB#50 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode for selective peripheral wake-up. These modes are hardware-controlled and retain RAM content, enabling rapid wake-up (<;1 μs from HALT) - essential for duty-cycled sensor applications using the R5F101GCDFB#50.
How many analog input channels and what ADC resolution does the R5F101GCDFB#50 provide?
The R5F101GCDFB#50 features a 10-bit successive-approximation ADC with up to 26 configurable analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins. It also integrates an internal temperature sensor and 1.45 V reference voltage source, enabling calibrated measurements without external components in the R5F101GCDFB#50.
