Product details
Overview
R7F100GMN2DFA#BA0 from Renesas is an RL78/G23 80-pin, 5.5-V, ultra-low-power 16-bit MCU with 768-KB code flash, 48-KB RAM, and integrated capacitive touch sensing unit (CTSU2L), designed for battery-powered consumer electronics requiring long runtime and human interface functionality.
For engineers reviewing the R7F100GMN2DFA#BA0 datasheet, R7F100GMN2DFA#BA0 pinout, R7F100GMN2DFA#BA0 application, or R7F100GMN2DFA#BA0 equivalent, key selection criteria include STOP-mode current (210 nA), 32-channel CTSU support, 12-bit ADC with 26 inputs, UARTA/LIN-capable serial interfaces, and LFQFP-80 (0.5-mm pitch) package compatibility with industrial temperature range (−40 to +85°C).
Technical Context
The R7F100GMN2DFA#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting variable instruction execution time (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode) and multiply/divide/accumulate instructions. It integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power sensor polling without CPU wake-up.
Peripheral integration includes Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and Realtime Clock (RTC) with alarm and BCD correction - all operating in low-power modes while maintaining system responsiveness and timing accuracy.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMN2DFA#BA0?
The R7F100GMN2DFA#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, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep functions, maintaining full register retention at 210 nA.
Does the R7F100GMN2DFA#BA0 support LIN bus communication, and which pins are used?
Yes, the R7F100GMN2DFA#BA0 supports LIN 2.2-compliant communication via its UARTA peripheral. Pins P00 (TxD1) and P01 (RxD1) are designated for LIN transceiver connection, and the UARTA module includes dedicated LIN break detection, sync field handling, and checksum generation - all configurable in hardware without CPU intervention.
How many capacitive touch channels does the R7F100GMN2DFA#BA0 support, and what configuration options exist?
The R7F100GMN2DFA#BA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It includes built-in noise cancellation, automatic drift compensation, and programmable scan timing - all managed by dedicated hardware, allowing touch sensing to run autonomously during SNOOZE mode without CPU involvement.
What debug interface does the R7F100GMN2DFA#BA0 use, and is JTAG supported?
The R7F100GMN2DFA#BA0 uses the single-wire debug (SWD)-compatible FINE interface via pins P40 (TOOL0) and RESET, supporting full on-chip debugging, flash programming, and real-time trace. JTAG is not implemented; Renesas' FINE interface provides equivalent functionality with reduced pin count and lower EMI compared to traditional JTAG.
Can the R7F100GMN2DFA#BA0 perform ADC conversions while in STOP mode, and if so, how?
No, the R7F100GMN2DFA#BA0 cannot perform ADC conversions in STOP mode. However, it supports autonomous ADC triggering via the SNOOZE mode sequencer (SMS): the SMS can initiate ADC scans, store results, and compare values - all while the CPU, flash, and RAM remain powered down. This achieves effective "ADC-in-STOP" behavior with 210-nA current draw and no CPU wake-up latency.
