Product details
Overview
R5F100GEDFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 10-bit ADC (12 channels), and real-time clock - designed for battery-powered industrial control and sensor interface applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100GEDFB#V0 datasheet, R5F100GEDFB#V0 pinout, R5F100GEDFB#V0 application, or R5F100GEDFB#V0 equivalent, key selection criteria include ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated LIN-capable UART, hardware multiplier/divider, and 48-pin LQFP-0.5mm pitch compatibility with space-constrained PCB layouts.
Technical Context
The R5F100GEDFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for RTC/watchdog.
Peripheral integration includes 2-channel DMA, 8-channel 16-bit timers, 12-bit interval timer, calendar-mode RTC with alarm/correction, and three serial interfaces - CSI (SPI-compatible), UART/LIN, and I²C - all configurable across multiple pins with programmable drive strength and pull-up options.

Yes, the R5F100GEDFB#V0 includes an on-chip debug interface compatible with Renesas E2 emulator and CS+ IDE. It supports full read/write/erase of code flash and data flash, including secure boot swap and flash shield window functions - all accessible via standard SWD/JTAG pins without external hardware.
How many serial communication interfaces does the R5F100GEDFB#V0 integrate, and which protocols are supported?
The R5F100GEDFB#V0 integrates three serial interface types: up to 8 CSI channels (SPI-compatible), up to 4 UART channels (with LIN bus support per ISO 17987), and up to 10 I²C/Simplified I²C channels. All are independently configurable and share no fixed pin assignments - allowing flexible routing across GPIO ports P0–P2.
What ADC capabilities does the R5F100GEDFB#V0 provide, and are internal references available?
The R5F100GEDFB#V0 features a 10-bit successive-approximation ADC with 12 analog input channels (ANI0–ANI11), programmable sample-and-hold, and scan mode. It includes an internal 1.45 V reference voltage and on-die temperature sensor - both accessible without external components and usable across the full 1.6–5.5 V VDD range.
Is the R5F100GEDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP (FB suffix) package - including R5F100GxxAFB, R5F100GxxDFB, and R5F100GxxGFB - share identical pinouts and electrical characteristics. Function allocation (e.g., UART vs. CSI on P10/P11) is software-configurable, enabling drop-in replacement across memory/temperature grades without PCB changes.
