Product details
Overview
R5F100LGDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade (−40°C to +85°C) RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and ultra-low-power operation (66 μA/MHz active, 0.57 μA in RTC+LVD mode). It targets battery-powered industrial sensors and programmable logic controllers.
For engineers reviewing the R5F100LGDFA#V0 datasheet, R5F100LGDFA#V0 pinout, R5F100LGDFA#V0 application, or R5F100LGDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package with 26-channel analog input capability, 12 KB on-chip RAM for real-time control buffers, and support for SNOOZE mode DMA transfers-critical for low-duty-cycle telemetry systems.
Technical Context
The R5F100LGDFA#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 banked 8-bit general-purpose registers and hardware multiplier/divider for deterministic motor control math.
Power management includes HALT, STOP, and SNOOZE modes, plus an on-chip voltage detector with 14 selectable LVD levels and POR circuit. The DMA controller supports 4 channels with 2-clock transfers between SFR and RAM, enabling background data movement during low-power operation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGDFB#V0 | Same core, memory, and peripherals but in 64-pin LFQFP (0.5 mm pitch, PLQP0064KF-A); 2 mm smaller footprint. | Preferred for space-constrained designs where PCB rework tolerance is higher; requires finer-pitch assembly capability. | Select when board area is critical and assembly process supports 0.5 mm pitch; not drop-in compatible due to different land pattern. |
| R5F101LGDFB#V0 | Identical package and pinout but lacks data flash (0 KB); retains 128 KB code flash and same peripherals. | Suitable for cost-sensitive applications where parameter storage is handled externally or unnecessary (e.g., fixed-function firmware). | Choose when data logging or field-upgradable configuration is not required; reduces BOM cost by eliminating data flash redundancy. |
Compared with R5F100LGDFA#V0, R5F100LGDFB#V0 saves board space at the expense of assembly complexity, while R5F101LGDFB#V0 removes data flash to lower unit cost-making it viable only when external EEPROM or cloud-based configuration replaces on-chip nonvolatile parameter storage.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100LGDFA#V0?
The R5F100LGDFA#V0 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this translates to approximately 2.1 mA total active current, enabling responsive real-time control while maintaining ultra-low-power credentials for intermittent operation.
Does the R5F100LGDFA#V0 support hardware debugging without external JTAG/SWD interfaces?
Yes, the R5F100LGDFA#V0 integrates on-chip debug functionality accessible via TOOLRxD on pin P11, allowing full programming and real-time debugging over a standard UART connection. This eliminates the need for dedicated debug headers, reducing PCB complexity and BOM cost in space-constrained designs.
How many analog input channels does the R5F100LGDFA#V0 support, and what is the ADC resolution?
The R5F100LGDFA#V0 supports 26 analog input channels with a 10-bit successive approximation register (SAR) ADC. It includes an internal 1.45 V reference and supports both single-ended and differential measurement modes, making it suitable for precision sensor interfacing without external reference components.
Can the R5F100LGDFA#V0 execute code while rewriting data flash memory?
Yes, the R5F100LGDFA#V0 supports Background Operation (BGO) for data flash, allowing the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors. This enables seamless firmware updates and parameter logging without interrupting real-time control tasks.
What industrial temperature grade does the R5F100LGDFA#V0 support, and how is it indicated in the part number?
The R5F100LGDFA#V0 is rated for −40°C to +85°C industrial operation, denoted by the "D" suffix in its family designation (R5F100LGDFA#V0 → "D" = Industrial grade). This ensures reliable performance across extended thermal ranges encountered in factory automation and outdoor infrastructure deployments.
