Product details
Overview
R7F100GMN3CFB#BA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 768 KB code flash, 48 KB RAM, and integrated capacitive touch sensing (CTSU2L), designed for industrial control panels requiring extended battery life and robust human-machine interface support.
For engineers reviewing the R7F100GMN3CFB#BA0 datasheet, R7F100GMN3CFB#BA0 pinout, R7F100GMN3CFB#BA0 application, or R7F100GMN3CFB#BA0 equivalent, key selection criteria include its 1.6–5.5 V operating range, 210-nA data retention current, STOP-mode wakeup time < 4 µs, and 80-pin LFQFP 0.50-mm pitch package compatibility with industrial temperature grade (−40 to +105°C).
Technical Context
The R7F100GMN3CFB#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and dual-clock domain operation (high-speed on-chip oscillator ±1.0% accuracy, low-speed 32.768 kHz oscillator with adjustability).
Key Specifications

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMN3CFB#BA0?
The R7F100GMN3CFB#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains timing specifications over the entire industrial temperature range (−40 to +105°C) without derating.
Does the R7F100GMN3CFB#BA0 support in-system programming and secure firmware updates?
Yes, the R7F100GMN3CFB#BA0 supports self-programming of both code and data flash memory, including boot swapping and flash shield window protection. Its 8 KB data flash supports background operation (BGO), allowing full CPU execution during rewrites-enabling secure, seamless over-the-air (OTA) updates without interrupting real-time tasks.
How many capacitive touch channels does the R7F100GMN3CFB#BA0 support, and what configuration options are available?
The R7F100GMN3CFB#BA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or up to 64 mutual-capacitance keys (8×8 matrix). It operates across the full 1.8–5.5 V supply range and includes built-in noise cancellation algorithms-no external RC networks or dedicated touch controller ICs are required.
What debug interfaces are available on the R7F100GMN3CFB#BA0, and are they accessible in all low-power modes?
The R7F100GMN3CFB#BA0 supports on-chip debugging via the TOOL0/TOOLRxD/TOOLTxD pins (SWD-compatible serial wire debug). Debug access remains functional in HALT and SNOOZE modes but is disabled in STOP and deep HALT modes to preserve ultra-low power. Full debug visibility-including register and memory inspection-is retained upon wakeup from HALT.
Can the R7F100GMN3CFB#BA0 generate precise PWM signals for motor control, and what timer resources are allocated for this function?
Yes, the R7F100GMN3CFB#BA0 supports high-resolution PWM generation using its Timer Array Unit (TAU) with 16 independent 16-bit channels. Each channel supports complementary output with programmable dead-time insertion, and the 32-bit interval timer provides sub-microsecond timing resolution for synchronized multi-phase motor control loops.
