Product details
Overview
R5F104GDGFB#30 from Renesas is a 48-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 128 KB flash, 12 KB RAM, and industrial-grade operation up to +105°C. 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, 16-bit timers, 10-bit ADC (16 channels), and on-chip RTC with calendar support - deployed in motor control and sensor interface modules.
For engineers reviewing the R5F104GDGFB#30 datasheet, R5F104GDGFB#30 pinout, R5F104GDGFB#30 application, or R5F104GDGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade (G-suffix), 128 KB code flash / 8 KB data flash memory split, and integrated event link controller (ELC) for deterministic peripheral triggering.
Technical Context
The R5F104GDGFB#30 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 ultra-low-power mode). It features a dedicated low-speed on-chip oscillator for watchdog timer operation and supports background operation (BGO) during data flash rewriting.
Its peripheral set includes 8-channel 16-bit Timer Array Unit (TAU), 1-channel 12-bit interval timer, 1-channel real-time clock with alarm/calendar, and 19–26 configurable event signals routed via Event Link Controller (ELC) to peripherals without CPU intervention - enabling deterministic timing-critical tasks in battery-powered industrial nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GEAFB#30 | Same 48-pin LFQFP package, but 64 KB flash / 5.5 KB RAM; lacks VCOUT0/VCOUT1 comparator outputs. | Suitable for simpler control tasks without analog feedback conditioning; lower memory footprint reduces BOM cost where firmware size <50 KB. | Select when application firmware fits in 64 KB and no on-chip voltage-controlled oscillator (VCO) output is required for sensor excitation. |
| R5F104GLAFB#30 | Same package and temperature grade, but 384 KB flash / 32 KB RAM; adds extra UART and I²C channels. | Targeted at feature-rich gateways needing dual Modbus ports or concurrent BLE + wired comms; higher memory supports RTOS integration. | Choose when future firmware expansion, OTA updates, or multi-protocol stack requirements exceed 128 KB flash capacity. |
Compared with R5F104GEAFB#30 and R5F104GLAFB#30, the R5F104GDGFB#30 strikes a balance between memory headroom (128 KB flash) and analog integration (dual VCOUT), making it optimal for closed-loop industrial controllers where both firmware complexity and sensor signal conditioning are critical.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GDGFB#30?
The R5F104GDGFB#30 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction execution times - from 0.03125 µs in high-speed mode to 30.5 µs in ultra-low-speed 32.768 kHz mode - enabling dynamic power/performance scaling in the R5F104GDGFB#30.
Does the R5F104GDGFB#30 support data flash rewriting during program execution?
Yes, the R5F104GDGFB#30 supports background operation (BGO) for data flash rewriting. While executing code from program memory, it can concurrently rewrite its 8 KB data flash memory - critical for logging runtime parameters or updating calibration tables without interrupting real-time control in the R5F104GDGFB#30.
What are the key analog features integrated into the R5F104GDGFB#30?
The R5F104GDGFB#30 integrates a 10-bit ADC with 16 input channels, internal 1.45 V reference voltage, on-chip temperature sensor, two VCOUT outputs (P120/P147), and dual comparators. These enable direct sensor excitation, ratiometric measurement, thermal monitoring, and analog threshold detection - all without external components in the R5F104GDGFB#30.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F104GDGFB#30?
The ELC in the R5F104GDGFB#30 routes up to 26 peripheral events (e.g., timer overflow, ADC end-of-conversion) directly to target functions like DMA triggers or PWM reload - bypassing CPU interrupts. This reduces latency to sub-microsecond levels and eliminates jitter in time-critical control loops within the R5F104GDGFB#30.
What is the industrial temperature rating and supply voltage range of the R5F104GDGFB#30?
The R5F104GDGFB#30 is rated for -40°C to +105°C operation (G-grade) and supports a wide 1.6 V to 5.5 V supply range. This enables deployment in harsh environments such as factory automation cabinets or automotive under-hood modules, while simplifying power design across mixed-voltage systems in the R5F104GDGFB#30.
