Product details
Overview
R5F100BGGNA#U0 from Renesas is a 32-pin RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI). It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100BGGNA#U0 datasheet, R5F100BGGNA#U0 pinout, R5F100BGGNA#U0 application, or R5F100BGGNA#U0 equivalent, key selection criteria include its HWQFN-32 package (5 × 5 mm, 0.5-mm pitch), -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, and self-programmable flash with boot swap capability.
Technical Context
The R5F100BGGNA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by a dedicated low-speed oscillator.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. Serial connectivity comprises up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable per pin via register settings.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100BGGNA#U0?
The R5F100BGGNA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C. The RL78 CPU core's 3-stage pipeline and optimized instruction set deliver deterministic timing for real-time control tasks in the R5F100BGGNA#U0.
Does the R5F100BGGNA#U0 include data flash memory, and what is its endurance specification?
Yes, the R5F100BGGNA#U0 includes 8 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing code execution from program memory during data flash rewrites - a key capability for reliable firmware updates and data logging in the R5F100BGGNA#U0.
What package type and pin count does the R5F100BGGNA#U0 use, and what is its thermal pad configuration?
The R5F100BGGNA#U0 uses a 32-pin HWQFN package (5 × 5 mm, 0.5-mm pitch) with an exposed thermal pad on the underside. This package is designated by the "NA" suffix in the part number and is supplied in tray format (#U0). The thermal pad must be soldered to a PCB copper pour for optimal thermal dissipation and electrical stability in the R5F100BGGNA#U0.
How does the R5F100BGGNA#U0 support low-power operation in battery-powered applications?
The R5F100BGGNA#U0 achieves ultra-low-power operation via HALT, STOP, and SNOOZE modes - consuming just 66 μA/MHz in active mode and 0.57 μA in STOP mode with RTC and LVD active. Its on-chip voltage detector (14-level LVD) and power-on-reset circuit ensure robust brown-out handling, making the R5F100BGGNA#U0 ideal for long-life battery applications like utility meters and wireless sensors.
Is the R5F100BGGNA#U0 qualified for industrial temperature range, and what does the 'G' suffix indicate?
Yes, the 'G' in R5F100BGGNA#U0 denotes industrial temperature grade with guaranteed operation from –40°C to +105°C. This qualification applies to the full device - including flash programming, ADC accuracy, and oscillator stability - and is validated per Renesas' industrial reliability standards. The R5F100BGGNA#U0 is therefore suitable for under-hood automotive auxiliary modules, factory-floor controllers, and outdoor metering equipment.
