Renesas R5F100GGGFB#X0

Overview

R5F100GGGFB#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 integrates a 32 MHz RL78 CPU core (41 DMIPS), 10-bit 26-channel ADC, RTC with calendar/alarm, 16-bit timers, UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD active).

For engineers reviewing the R5F100GGGFB#X0 datasheet, R5F100GGGFB#X0 pinout, R5F100GGGFB#X0 application, or R5F100GGGFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm-pitch package, G-grade temperature rating (–40°C to +105°C), integrated data flash with 1M write cycles, and support for background data flash rewriting during program execution.

Technical Context

The R5F100GGGFB#X0 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with BGO capability, and 12 KB SRAM - all accessible within a 1 MB address space.

Peripherals include dual DMA channels, 16-bit timer array (12 channels), real-time clock with calendar and correction, 10-bit ADC with internal reference and temperature sensor, and serial interfaces (CSI, UART/LIN, I²C) scalable across 2–10 channels depending on variant configuration.

FAQ

What is the maximum operating frequency of the R5F100GGGFB#X0?

The R5F100GGGFB#X0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. The oscillator accuracy is ±1.0% over VDD = 1.8–5.5 V and TA = –20°C to +85°C. For R5F100GGGFB#X0, this full-speed operation is guaranteed across its rated industrial temperature range (–40°C to +105°C) with appropriate decoupling and layout.

Does the R5F100GGGFB#X0 support in-system programming via standard interfaces?

Yes, the R5F100GGGFB#X0 supports in-system programming through its on-chip debug interface using the dedicated TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and Flash Development Toolkit. It does not require external programming hardware beyond standard SWD/JTAG adapters, and self-programming functions allow firmware updates in the field without removing the R5F100GGGFB#X0 from the PCB.

How many ADC channels are available on the R5F100GGGFB#X0, and what is their resolution?

The R5F100GGGFB#X0 integrates a 10-bit successive approximation ADC with up to 26 analog input channels (ANI0–ANI25). It includes an internal 1.45 V reference voltage and a calibrated temperature sensor usable for ambient monitoring. Conversion time is programmable down to 1.1 μs per sample, and the ADC operates across the full 1.6–5.5 V VDD range without external references.

What packaging and lead pitch does the R5F100GGGFB#X0 use?

The R5F100GGGFB#X0 uses a 48-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 7 mm × 7 mm body size and 0.50 mm lead pitch. The #X0 suffix confirms embossed tape packaging, and the FB designation explicitly identifies the LFQFP-0.5mm variant - distinct from HWQFN or LQFP-0.65mm alternatives in the same family.

Is the R5F100GGGFB#X0 qualified for industrial temperature operation?

Yes, the R5F100GGGFB#X0 is rated for industrial operation from –40°C to +105°C, indicated by the "G" in its part number. This qualification covers all specified electrical parameters including flash endurance, ADC linearity, oscillator stability, and I/O drive strength - validated per JEDEC JESD22-A104 and JESD22-A108 standards for extended temperature environments.
