Product details
Overview
R5F104GFGFB#30 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit MCU with ultra-low-power operation (66 μA/MHz), 32 MHz max CPU speed, and integrated 10-bit ADC (20-channel), UART/SCI/I²C interfaces, RTC, and hardware DTC/ELC peripherals - deployed in battery-powered industrial sensor nodes and motor control subsystems.
For engineers reviewing the R5F104GFGFB#30 datasheet, R5F104GFGFB#30 pinout, R5F104GFGFB#30 application, or R5F104GFGFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature rating (G-suffix), 0.5 mm pitch LFQFP-48 package, 1.6–5.5 V supply range, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104GFGFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a configurable Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE low-power modes, with real-time clock operation at 0.60 μA and high-accuracy on-chip oscillator (±1.0% over -20 to +85°C). The device supports self-programming of code/data flash with boot swapping and flash shield window protection.

FAQ
What is the maximum operating frequency and power consumption of the R5F104GFGFB#30?
The R5F104GFGFB#30 operates at up to 32 MHz with 44 DMIPS performance and achieves 66 μA/MHz active current. In STOP mode with only RTC and LVD enabled, it consumes just 0.60 μA - making it ideal for battery-backed applications where ultra-low quiescent current is critical. Its high-accuracy on-chip oscillator (±1.0%) eliminates need for external crystals in many use cases.
Does the R5F104GFGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104GFGFB#30 supports full in-system programming via its on-chip debug interface (using P50/P51 UART pins) and includes flash shield window protection to prevent unauthorized read/write access. It also enables background data flash rewriting - allowing firmware parameters to be updated while application code continues executing from program memory.
What analog peripherals are integrated into the R5F104GFGFB#30?
The R5F104GFGFB#30 integrates a 10-bit successive-approximation ADC with up to 20 input channels, internal 1.45 V reference voltage, and temperature sensor. It also includes an 8-bit D/A converter (up to two channels), two analog comparators with window mode, and dedicated AVREFP/AVREFM pins for precision analog measurement across its 1.6–5.5 V supply range.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F104GFGFB#30?
The ELC in the R5F104GFGFB#30 enables direct hardware linking of 19–26 peripheral events (e.g., ADC conversion complete, timer overflow) to target functions (e.g., DTC activation, interrupt generation) without CPU involvement. This reduces interrupt latency to sub-microsecond levels and frees CPU cycles for higher-layer tasks - essential for deterministic control in motor drives and industrial automation.
Is the R5F104GFGFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 48-pin LFQFP-0.5 mm pitch package - including R5F104GFGFB#30, R5F104GGGFB#30, and R5F104GHGFB#30 - share identical pinouts and electrical characteristics. Firmware and PCB designs are interchangeable across these variants, enabling seamless scalability from 96 KB to 192 KB flash without layout changes.
