Overview
R5F100GDDFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 10-bit ADC (26 channels), RTC, and low-power modes for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F100GDDFB#V0 datasheet, R5F100GDDFB#V0 pinout, R5F100GDDFB#V0 application, or R5F100GDDFB#V0 equivalent, key selection criteria include its G-grade temperature range (−40°C to +105°C), integrated data flash with background operation, 48-pin LFQFP package (7 × 7 mm, 0.5-mm pitch), and support for LIN-bus via UART.
Technical Context
The R5F100GDDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It features dual clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock for ultra-low-power peripherals.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GAGFB#V0 | G-grade (−40°C to +105°C), same 128 KB flash/8 KB data flash/12 KB RAM, but 48-pin HWQFN (7 × 7 mm, 0.5-mm pitch) | Requires PCB redesign due to different footprint and thermal pad; better thermal dissipation in high-power density layouts | Select when board space is constrained and thermal performance outweighs rework cost |
| R5F101GDDFB#V0 | Same package and pinout, but no data flash (0 KB); retains 128 KB code flash, 12 KB RAM, and identical peripherals | Suitable where firmware updates occur only via external host or where EEPROM emulation is handled externally | Select when data logging or field firmware updates are not required - lowers cost and simplifies qualification |
Compared with R5F100GDDFB#V0, R5F100GAGFB#V0 offers identical functionality in a smaller-footprint HWQFN package with enhanced thermal performance, while R5F101GDDFB#V0 removes data flash to reduce cost and complexity where non-volatile parameter storage is managed externally.

FAQ
What is the maximum operating frequency and processing performance of the R5F100GDDFB#V0?
The R5F100GDDFB#V0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The R5F100GDDFB#V0 sustains this performance across its full industrial temperature range (−40°C to +105°C), making it suitable for real-time control tasks such as motor commutation and sensor fusion.
Does the R5F100GDDFB#V0 include integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100GDDFB#V0 includes 8 KB of on-chip data flash memory. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. The rated endurance is 1,000,000 write cycles (typical), with rewrite voltage compatibility across the full supply range (1.8 V to 5.5 V). This enables reliable parameter storage and firmware update staging in the R5F100GDDFB#V0 without external EEPROM.
What package type and pin count does the R5F100GDDFB#V0 use, and is it RoHS-compliant?
The R5F100GDDFB#V0 uses a 48-pin LFQFP package measuring 7 mm × 7 mm with 0.5-mm pitch. It is RoHS-compliant and rated MSL-3 per JEDEC J-STD-020. The #V0 suffix indicates tray packaging, and the FB designation confirms the LFQFP form factor. This package balances I/O density, thermal performance, and manufacturability for industrial PCB assembly.
How does the R5F100GDDFB#V0 support low-power operation in battery-powered applications?
The R5F100GDDFB#V0 achieves ultra-low-power operation with 66 μA/MHz active current and just 0.57 μA in STOP mode with RTC and LVD enabled. Its HALT, STOP, and SNOOZE modes, combined with programmable LVD thresholds and multiple clock sources (including 32.768 kHz subsystem clock), allow precise power-state tuning. These features make the R5F100GDDFB#V0 ideal for energy-harvesting and multi-year battery applications like wireless sensor nodes.
Which communication interfaces are integrated into the R5F100GDDFB#V0, and does it support LIN bus?
The R5F100GDDFB#V0 integrates UART, I²C, and CSI (Renesas' SPI-compatible interface) with up to 4, 10, and 8 channels respectively. Its UART peripheral supports LIN bus protocol (ISO 17987) in hardware, including break detection, sync field handling, and checksum calculation. This native LIN capability eliminates external transceivers in automotive body control and industrial network nodes using the R5F100GDDFB#V0.
