Product details
Overview
R5F104GHAFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G) RL78/G14 16-bit MCU with 128 KB flash, 8 KB data flash, 16 KB RAM, and operation up to 32 MHz delivering 44 DMIPS. It integrates RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD) for embedded control in space-constrained industrial sensors and motor drives.
For engineers reviewing the R5F104GHAFB#30 datasheet, R5F104GHAFB#30 pinout, R5F104GHAFB#30 application, or R5F104GHAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, integrated event link controller (ELC), and support for background data flash rewriting during program execution.
Technical Context
The R5F104GHAFB#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-speed mode). It features on-chip high-accuracy oscillator (±1.0% over VDD=1.8–5.5 V, TA=−20 to +85°C) and dual-clock domain operation for independent peripheral timing.
Its peripheral set includes Timer Array Unit (TAU) with 8 channels, Real-time Clock with calendar and alarm, 19–26 configurable event signals routed via Event Link Controller (ELC), and Data Transfer Controller (DTC) supporting chain transfer for efficient memory-to-peripheral movement without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GHAFB#50 | Identical silicon; differs only in packaging specification (embossed tape vs. tray). | No functional or electrical difference; intended for automated SMT assembly lines requiring tape-and-reel feed. | Select #50 for high-volume pick-and-place production; #30 is optimized for manual prototyping and small-batch evaluation. |
| R5F104GLAFB#30 | Same package and temp grade, but 384 KB flash, 32 KB RAM, and enhanced peripheral count (e.g., +2 UART, +4 ADC channels). | Required for applications needing larger firmware footprint, more complex communication stacks, or higher channel-count analog acquisition. | Choose R5F104GLAFB#30 when future firmware scalability or additional peripherals (e.g., dual UART + LIN) are mandatory; R5F104GHAFB#30 suffices for fixed-feature deployments. |
Compared with R5F104GHAFB#30, the #50 variant offers identical functionality in tape-and-reel format for automated manufacturing, while R5F104GLAFB#30 provides scalable memory and peripherals for feature-rich upgrades-neither is pin-compatible with unrelated families like RL78/G13 or RX100.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GHAFB#30?
The R5F104GHAFB#30 operates at up to 32 MHz and delivers 44 DMIPS (Dhrystone MIPS) under benchmark conditions. This performance level supports real-time control loops, protocol stack processing (e.g., Modbus, LIN), and sensor fusion algorithms without requiring external accelerators. The RL78 core achieves this efficiency through its 3-stage pipeline and optimized instruction set, making the R5F104GHAFB#30 suitable for applications where deterministic timing and low power are both critical.
Does the R5F104GHAFB#30 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104GHAFB#30 supports Background Operation (BGO) for data flash, allowing the CPU to execute instructions from program memory while simultaneously rewriting the 8 KB data flash. This capability is essential for firmware-over-the-air (FOTA) updates, parameter logging, and calibration storage without system interruption. The R5F104GHAFB#30 guarantees 1,000,000 rewrite cycles (typical) at VDD = 1.8–5.5 V, and the flash library reserves RAM starting at address FE900H for this function.
What industrial temperature range does the R5F104GHAFB#30 support, and how is it indicated in the part number?
The R5F104GHAFB#30 supports an industrial ambient temperature range of −40°C to +105°C, denoted by the "G" in the fourth character position of the part number (R5F104GHAFB#30). This grade ensures reliable operation in demanding environments such as factory automation controllers, outdoor metering equipment, and motor drive enclosures. The device maintains specified timing, analog accuracy, and low-power mode behavior across this full range, validated per JEDEC JESD22-A104.
How many analog input channels does the 10-bit ADC in the R5F104GHAFB#30 support, and what reference options are available?
The R5F104GHAFB#30 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins). It supports two reference voltage sources: externally applied AVREFP/AVREFM differential pair or internal 1.45 V reference (VREF). The internal reference provides stable scaling across temperature and supply voltage variations, enabling accurate sensor measurements in battery-operated or unregulated systems-key for consistent performance in the R5F104GHAFB#30's target applications.
What is the purpose of the REGC pin on the R5F104GHAFB#30, and how must it be connected?
The REGC pin on the R5F104GHAFB#30 is the bypass terminal for the on-chip voltage regulator that powers the analog and RTC domains. It must be connected to VSS via a 0.47 µF to 1.0 µF ceramic capacitor placed as close as possible to the pin. Failure to properly decouple REGC risks unstable RTC operation, inaccurate ADC readings, and erratic LVD behavior. This requirement is explicitly mandated in the datasheet (R01DS0053EJ0370) and applies universally across all RL78/G14 variants, including the R5F104GHAFB#30.
