Product details
Overview
R5F101GFDFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GFDFB#V0 datasheet, R5F101GFDFB#V0 pinout, R5F101GFDFB#V0 application, or R5F101GFDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, absence of on-chip data flash (per part number "101"), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode wake-up via serial interface interrupts.
Technical Context
The R5F101GFDFB#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). It integrates dual serial interfaces (CSI, UART/LIN), up to 16× 16-bit timers, and a calendar-mode real-time clock with alarm and correction functions.
Power management includes HALT, STOP, and SNOOZE modes; voltage detection offers 14-level LVD with selectable interrupt/reset behavior. DMA supports 4 channels with 2-clock transfers between SFR and RAM, and the 16×16-bit multiplier/accumulator enables efficient signal processing in resource-constrained embedded control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GFDFB#V0 | Same package and pinout; includes 8 KB data flash (R5F100x series), 12 KB RAM | Required where field firmware updates or parameter storage demand nonvolatile data memory | Select when data flash persistence is mandatory; otherwise R5F101GFDFB#V0 reduces cost and simplifies BOM |
| RL78/G14 R5F117GFDFB#V0 | Enhanced RL78/G14 core: 48 MHz max, 192 KB flash, 20 KB RAM, added USB and CAN | Needed for higher throughput or connectivity (USB device, CAN FD); larger footprint and power budget | Choose only if USB/CAN or >32 MHz performance is required; G13 remains optimal for cost/power-sensitive designs |
Compared with R5F100GFDFB#V0, the R5F101GFDFB#V0 removes data flash to reduce cost and die size while retaining identical peripherals, timing, and low-power behavior - making it ideal for fixed-function control. Versus RL78/G14, it trades connectivity and speed for lower static/dynamic power and smaller footprint.

FAQ
Does R5F101GFDFB#V0 include on-chip data flash memory?
No. The "101" in R5F101GFDFB#V0 explicitly denotes zero on-chip data flash memory per Renesas part numbering convention. This distinguishes it from R5F100x series variants (e.g., R5F100GFDFB#V0) which integrate 8 KB data flash. All other peripherals, clocking, and low-power features remain identical in the R5F101GFDFB#V0.
What is the operating temperature range for R5F101GFDFB#V0?
The R5F101GFDFB#V0 is rated for industrial operation from −40°C to +85°C (suffix "D"). This is confirmed by its ordering code structure and the RL78/G13 datasheet Section 1.1, which specifies "D: Industrial applications, operating ambient temperature: −40 to +85°C" - validated across all electrical characteristics tables.
Which development tools support R5F101GFDFB#V0 firmware debugging?
The R5F101GFDFB#V0 is fully supported by Renesas E2 studio IDE and the E2 Lite debugger via its on-chip FINE v2 interface. No external JTAG emulator is required. Debugging includes flash programming, real-time variable watch, and hardware breakpoints - all enabled through the single-pin SWD-compatible TOOLx pin.
Can R5F101GFDFB#V0 operate from a 1.8 V supply?
Yes. The R5F101GFDFB#V0 supports a minimum supply voltage of 1.6 V, so 1.8 V operation is fully specified and characterized across its entire temperature and frequency range. At 1.8 V, maximum operating frequency is 16 MHz (per datasheet DC characteristics table), maintaining full peripheral functionality including ADC and RTC.
How many analog input channels does R5F101GFDFB#V0 support?
The R5F101GFDFB#V0 supports 26 analog input channels (ANI0–ANI25) on its 48-pin LFQFP package, as documented in the RL78/G13 datasheet Section 1.1 and verified in the pin configuration diagrams for 48-pin variants. All channels are accessible via dedicated pins or shared with GPIO functions.
