Product details
Overview
R5F100GDGFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (24 channels), RTC, and low-power modes including STOP (0.57 μA) for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F100GDGFB#10 datasheet, R5F100GDGFB#10 pinout, R5F100GDGFB#10 application, or R5F100GDGFB#10 equivalent, key selection criteria include its industrial-grade temperature rating (–40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation during program execution, and support for LIN-bus UART and I²C in compact 7 mm × 7 mm LFQFP-48 packaging.
Technical Context
The R5F100GDGFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It supports dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz).
Its peripheral set includes 12× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and serial interfaces: up to 8× CSI, 4× UART/LIN, and 10× I²C/Simplified I²C - all mapped to dedicated pins in the 48-pin LFQFP package.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100GDGFB#10?
The R5F100GDGFB#10 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. Its minimum instruction execution time is 0.03125 μs in high-speed mode, confirmed in the RL78/G13 datasheet Rev.3.80 Section 1.1.
Does the R5F100GDGFB#10 support LIN bus communication, and if so, how is it implemented?
Yes, the R5F100GDGFB#10 supports LIN bus communication through its UART peripheral, which includes LIN 2.2 protocol features such as automatic sync-field detection, checksum generation (classic/enhanced), and break detection. This is implemented without external transceivers when paired with a compliant LIN physical layer driver.
What are the memory resources allocated to the R5F100GDGFB#10, and how is data flash utilized in firmware design?
The R5F100GDGFB#10 includes 128 KB code flash, 8 KB data flash, and 12 KB RAM. The data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash - enabling seamless firmware updates and parameter storage without halting real-time tasks.
How does the R5F100GDGFB#10 achieve ultra-low power consumption, and what is its lowest active current draw?
The R5F100GDGFB#10 achieves ultra-low power via multiple low-power modes: STOP mode draws just 0.57 μA with RTC and LVD active, HALT mode consumes 66 μA/MHz, and SNOOZE mode enables peripheral operation while CPU sleeps. These are enabled by its advanced power gating and clock gating architecture detailed in Section 1.1 of the datasheet.
Is the R5F100GDGFB#10 pin-compatible with other RL78/G13 variants in the 48-pin LFQFP package?
Yes, the R5F100GDGFB#10 shares identical pinout and footprint with all other RL78/G13 devices in the 48-pin LFQFP-0.5mm package (e.g., R5F100GAGFB#10, R5F101GDGFB#10), including matching power, ground, reset, oscillator, and peripheral signal assignments - enabling hardware reuse across performance and feature variants.
