Product details
Overview
R5F100MLDFA#30 from Renesas is an RL78/G13 80-pin LQFP-0.65mm microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial embedded control in HVAC, motor drives, and smart meters.
For engineers reviewing the R5F100MLDFA#30 datasheet, R5F100MLDFA#30 pinout, R5F100MLDFA#30 application, or R5F100MLDFA#30 equivalent, this device delivers verified 32 MHz CPU performance (41 DMIPS), integrated 10-bit ADC (26 channels), real-time clock with calendar, and hardware DMA - all within a -40°C to +85°C industrial temperature grade and LQFP-80 package.
Technical Context
The R5F100MLDFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and subsystem clock (32.768 kHz).
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 4× UART/LIN interfaces, 2–8× CSI/SPI channels, and a 12-bit interval timer - all managed via dedicated SFRs and supported by 4-channel DMA for zero-CPU-overhead memory transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLDFA#50 | Identical silicon; differs only in packaging - embossed tape instead of tray | No functional difference; selected for automated SMT line compatibility | Choose #50 for high-volume pick-and-place assembly; #30 for manual prototyping or low-volume production |
| R5F101MLDFA#30 | Omits 8 KB data flash; retains same 512 KB code flash, 32 KB RAM, and peripheral set | Suitable where firmware update persistence is handled externally or via external EEPROM | Select when data logging or field firmware storage is unnecessary - reduces cost and simplifies qualification |
Compared with R5F100MLDFA#30, the #50 variant offers identical electrical and functional behavior with optimized packaging for automation, while R5F101MLDFA#30 removes data flash to lower BOM cost where non-volatile parameter storage is implemented externally.

FAQ
What is the operating temperature range for R5F100MLDFA#30?
The R5F100MLDFA#30 is rated for industrial operation from −40°C to +85°C. This rating is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Section 1.1), where the "D" suffix in the part number explicitly denotes the industrial temperature grade. It does not support the extended −40°C to +105°C range (G grade) or consumer −40°C to +85°C (A grade with different qualification).
Does R5F100MLDFA#30 include a hardware multiplier/divider?
Yes, the R5F100MLDFA#30 includes a dedicated hardware multiplier and divider unit supporting 16×16→32-bit (signed/unsigned), 32÷32→32-bit (unsigned), and 16×16+32→32-bit (signed/unsigned) operations. This unit operates independently of the CPU core and is accessible via specific SFRs, enabling efficient math-intensive tasks like motor control algorithms without software emulation overhead.
How many analog input channels does R5F100MLDFA#30 support?
The R5F100MLDFA#30 supports up to 26 analog input channels for its 10-bit A/D converter. This count is specified in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Section 1.1 Features) and corresponds to the 80-pin LQFP package variant, which exposes the maximum number of ANIxx pins. Channel mapping is fixed per pin assignment and documented in the device's pin configuration table.
Is R5F100MLDFA#30 pin-compatible with other RL78/G13 80-pin variants?
Yes, all RL78/G13 80-pin LQFP-0.65mm variants - including R5F100MLDFA#30, R5F100MLAFA#30, and R5F101MLDFA#30 - share identical pinouts and mechanical footprint. The "M" in the part number confirms 80-pin LQFP, and the datasheet's pin configuration diagrams (Section 1.3.7) verify consistent signal assignment across all M-series devices in this package type.
What debug interface does R5F100MLDFA#30 support?
The R5F100MLDFA#30 supports Renesas' on-chip debug interface via the FINE (Fast In-Circuit Emulator) protocol using dedicated pins (e.g., RES#, CLK, DATA). It requires no external debug probe hardware beyond a standard E2 emulator or E2 Lite debugger. Debug features include full break/watchpoint capability, real-time trace buffer access, and flash programming - all enabled through the integrated debug circuitry described in Section 1.1 of the datasheet.
