Product details
Overview
R5F104LGGFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 512 KB flash, 8 KB data flash, 48 KB RAM, and -40 to +105°C operation. It delivers 44 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.60 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 12-channel 16-bit timers, 20-channel 10-bit ADC, and real-time clock - deployed in motor control and industrial HMI systems.
For engineers reviewing the R5F104LGGFB#30 datasheet, R5F104LGGFB#30 pinout, R5F104LGGFB#30 application, or R5F104LGGFB#30 equivalent, key selection criteria include its G-grade temperature rating, LFQFP-64 0.5 mm pitch package, integrated DTC/ELC peripherals for deterministic low-latency event handling, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104LGGFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 512 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 48 KB RAM - all accessible within a 1 MB address space.
Peripherals are orchestrated via Event Link Controller (ELC) with up to 26 event sources and Data Transfer Controller (DTC) supporting chain transfer, enabling autonomous peripheral-to-memory/data movement without CPU intervention. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip LVD with 14 selectable voltage thresholds and POR circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LGGB#30 | Same 64-pin LFQFP package and 512 KB flash, but rated for -40 to +85°C (D-grade) instead of +105°C (G-grade). | Suitable for commercial/industrial ambient environments without extended thermal stress; not qualified for high-temp enclosures or power electronics proximity. | Select when operating ambient stays ≤85°C and cost sensitivity outweighs extended temperature margin. |
| R5F104LJGFB#30 | Identical G-grade temperature rating and LFQFP-64 package, but with 256 KB flash and 24 KB RAM - reduced memory footprint. | Appropriate for streamlined firmware with minimal feature set (e.g., basic motor control without advanced diagnostics or OTA update capability). | Choose when application firmware fits within 256 KB and lower BOM cost is prioritized over future scalability. |
Compared with R5F104LGGFB#30, R5F104LGGB#30 trades extended temperature resilience for broader commercial availability, while R5F104LJGFB#30 reduces memory resources to lower unit cost - both retain identical pinout and peripheral sets, enabling layout reuse where thermal or memory margins allow.

FAQ
What is the maximum operating temperature specification for the R5F104LGGFB#30?
The R5F104LGGFB#30 is rated for industrial G-grade operation from -40°C to +105°C ambient temperature. This specification is confirmed in the ordering information section of the RL78/G14 datasheet (R01DS0053EJ0370), where the "G" suffix denotes extended temperature qualification - making it suitable for deployment near power electronics, in sealed enclosures, or in high-ambient industrial settings where standard D-grade (-40 to +85°C) devices would fail.
Does the R5F104LGGFB#30 support background data flash rewriting while executing application code?
Yes, the R5F104LGGFB#30 supports Background Operation (BGO) for data flash. As specified in the datasheet, instructions can be executed from program memory while data flash is being rewritten - enabling uninterrupted real-time operation during firmware updates, calibration storage, or event logging. The data flash capacity is 8 KB with a typical endurance of 1,000,000 rewrite cycles at VDD = 1.8–5.5 V.
What package type and pin pitch does the R5F104LGGFB#30 use?
The R5F104LGGFB#30 uses a 64-pin LFQFP package (10 × 10 mm body size) with 0.5 mm pin pitch, as defined by the "FB" suffix in the part number and confirmed in Table 1-1 of the RL78/G14 datasheet. This fine-pitch quad flat package supports high I/O density while maintaining compatibility with standard surface-mount assembly processes and reflow profiles.
How many analog input channels does the R5F104LGGFB#30 support, and what is the ADC resolution?
The R5F104LGGFB#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), as documented in the "A/D Converter" feature list. It includes an internal 1.45 V reference voltage and on-die temperature sensor - allowing direct measurement of analog signals across its full 1.6–5.5 V supply range without external reference components.
Is the R5F104LGGFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104LGGFB#30 is pin-compatible with all other RL78/G14 devices in the 64-pin LFQFP-0.5 mm package (e.g., R5F104LJGFB#30, R5F104LKAFB), sharing identical pin configuration, electrical characteristics, and peripheral mapping. This allows hardware reuse across firmware variants - for example, upgrading from 256 KB to 512 KB flash without PCB redesign - provided the target variant supports the required peripheral features.
