Product details
Overview
R5F100GHGFB#X0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 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 just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100GHGFB#X0 datasheet, R5F100GHGFB#X0 pinout, R5F100GHGFB#X0 application, or R5F100GHGFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M-cycle endurance, low-power SNOOZE/STOP/HALT modes, and hardware multiplier/divider for deterministic control math.
Technical Context
The R5F100GHGFB#X0 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs min @32 MHz to 30.5 μs @32.768 kHz). It supports background operation during data flash rewriting and includes dedicated low-speed on-chip oscillator for watchdog timer independence.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor - all operating across 1.6–5.5 V supply and compatible with 1.8/2.5/3.0 V logic interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GHAFB#X0 | Same 128 KB flash, 8 KB data flash, 12 KB RAM, but A-grade (−40°C to +85°C) temperature range | Suitable for consumer or indoor industrial use where extended temperature is not required | Select when cost optimization is prioritized and ambient operating temperature remains ≤+85°C |
| R5F101GHGFB#X0 | Identical package and pinout, but lacks data flash memory (0 KB); retains same 128 KB code flash and peripherals | Used where firmware updates occur only via external host or where EEPROM-like nonvolatile storage is handled externally | Choose when data logging or field firmware patching is unnecessary, reducing BOM cost and simplifying qualification |
Compared with R5F100GHGFB#X0, the R5F100GHAFB#X0 trades industrial temperature margin for lower unit cost, while the R5F101GHGFB#X0 removes data flash to reduce silicon area - both retain identical peripheral sets, clocking, and low-power modes, making them drop-in alternatives only where those specific features are unused.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100GHGFB#X0?
The R5F100GHGFB#X0 operates at up to 32 MHz and achieves 41 DMIPS (Dhrystone MIPS) under standard benchmark conditions. This performance level supports real-time tasks such as motor control loops, sensor fusion, and protocol stack processing while maintaining sub-100 μA/MHz efficiency - verified in Renesas' R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100GHGFB#X0 include an integrated temperature sensor and voltage reference?
Yes, the R5F100GHGFB#X0 integrates a calibrated temperature sensor and a 1.45 V internal reference voltage source, both accessible via the ADC. These features eliminate the need for external components in thermal monitoring and precision analog measurement applications - confirmed in the "A/D converter" subsection of the R01DS0131EJ0380 datasheet.
What low-power modes does the R5F100GHGFB#X0 support, and what is its lowest current consumption?
The R5F100GHGFB#X0 supports HALT, STOP, and SNOOZE modes, with minimum current draw of 0.57 μA in STOP mode while retaining RTC and LVD functionality. This enables decade-long operation on primary batteries - specified in the "Ultra-low power consumption technology" section of the R01DS0131EJ0380 datasheet.
Is the R5F100GHGFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP package (e.g., R5F100GHAFB#X0, R5F101GHGFB#X0) share identical pinouts and electrical characteristics. This allows hardware reuse across variants differing only in memory configuration or temperature grade - documented in Table 1-1 and Figure 1-1 of the R01DS0131EJ0380 datasheet.
What development tools are officially supported for the R5F100GHGFB#X0?
Renesas provides full support for the R5F100GHGFB#X0 via the CS+ IDE, e² studio (with GCC RL78 toolchain), and the E2 emulator Lite. Hardware evaluation is enabled by the YRDKRL78G13 kit - all validated and listed in the RL78/G13 Target Board User's Manual (R01UH0297EJ0200) and Renesas' official product page for R5F100GHGFB#X0.
