Product details
Overview
R5F100GFAFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, 12 KB RAM, and operation up to 32 MHz delivering 41 DMIPS - deployed in battery-powered sensor nodes, HVAC controllers, and smart metering interfaces requiring ultra-low power and integrated analog peripherals.
For engineers reviewing the R5F100GFAFB#X0 datasheet, R5F100GFAFB#X0 pinout, R5F100GFAFB#X0 application, or R5F100GFAFB#X0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, 0.57 μA STOP mode current, 10-bit ADC with 26 channels, RTC with calendar/alarm, and dual SPI/I²C/UART interfaces for embedded control and telemetry subsystems.
Technical Context
The R5F100GFAFB#X0 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 integrates a 12-bit interval timer, real-time clock with 99-year calendar, and watchdog timer powered by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 16-bit timers (8–16 channels), DMA controller (4 channels), and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C - all configurable for mixed-signal industrial sensing and actuation tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GFAFB#X0 | No data flash (0 KB); identical core, peripherals, package, and pinout | Not suitable where nonvolatile parameter storage or field firmware updates are required | Select when cost sensitivity outweighs need for persistent data logging or bootloader flexibility |

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GFAFB#X0?
The R5F100GFAFB#X0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline architecture and validated under standard test conditions per Renesas documentation. The R5F100GFAFB#X0 achieves this throughput while maintaining ultra-low active current (66 μA/MHz), making it suitable for compute-constrained yet power-sensitive applications.
Does the R5F100GFAFB#X0 include an integrated temperature sensor and voltage reference?
Yes, the R5F100GFAFB#X0 integrates a factory-calibrated temperature sensor and a 1.45 V internal reference voltage source usable with its 10-bit ADC. Both features are accessible via dedicated ANI channels and require no external components. This capability is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380) Section 1.1 Features and is enabled only in HS (high-speed main) mode - a setting automatically managed by the R5F100GFAFB#X0's power control unit.
What are the supported low-power modes and their typical current consumption for the R5F100GFAFB#X0?
The R5F100GFAFB#X0 supports HALT (66 μA/MHz), STOP (0.57 μA), and SNOOZE modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA - verified at VDD = 3.0 V, TA = 25°C. These values are specified in the official datasheet and reflect actual silicon characterization. The R5F100GFAFB#X0's low-power architecture enables multi-year operation on primary lithium cells in applications like utility meters and remote sensors.
Can the R5F100GFAFB#X0 perform background data flash rewriting while executing application code?
Yes, the R5F100GFAFB#X0 supports Background Operation (BGO) for data flash, allowing program code to run from flash memory while simultaneously rewriting the 8 KB data flash area. This feature is implemented in hardware and documented in Section 1.1 Features of the R01DS0131EJ0380 datasheet. BGO eliminates interrupt latency during firmware updates or parameter saves - a critical capability for the R5F100GFAFB#X0 in always-on industrial controllers.
Is the R5F100GFAFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP (FB) package - including R5F100GFAFB#X0, R5F100GGAFB#X0, and R5F101GFAFB#X0 - share identical pinouts and electrical characteristics. This compatibility is guaranteed by Renesas' package-level design consistency and confirmed in Table 1-1 of the R01DS0131EJ0380 datasheet. Engineers may substitute within the same memory/config variant group without PCB revision, provided firmware accounts for flash/RAM differences.
