Overview
R7F100GMG3CFB#AA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V; features include 12-bit A/D converter (26 channels), capacitive touch sensing (up to 64 keys), RTC, and SNOOZE mode sequencer for battery-powered industrial HMI applications.
For engineers reviewing the R7F100GMG3CFB#AA0 datasheet, R7F100GMG3CFB#AA0 pinout, R7F100GMG3CFB#AA0 application, or R7F100GMG3CFB#AA0 equivalent, key selection criteria include verified 80-pin LFQFP (12 × 12 mm, 0.50-mm pitch) package compatibility, -40 to +105°C industrial temperature rating (C-grade), and confirmed support for background data flash rewriting (1M-cycle endurance) and 210-nA RAM retention.
Technical Context
The R7F100GMG3CFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU wake-up.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, 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).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ3CFB#AA0 | 64-pin LFQFP, 256 KB flash, 24 KB RAM, same core/peripherals but fewer I/O (64 vs. 80 pins) and no CTSU2L mutual capacitance support | Targeted at space-constrained designs where 64-pin footprint suffices and full 64-key touch matrix is unnecessary | Select when PCB area is critical and touch requirements are limited to ≤32 self-capacitance keys |
| R7F100GMK3CFB#AA0 | Same 80-pin LFQFP package and CTSU2L, but 384 KB flash + 32 KB RAM - higher memory capacity with identical pinout and peripheral set | Required for applications needing larger firmware (e.g., OTA stack, advanced UI frameworks) or extended data logging buffers | Select when future firmware growth or enhanced data buffering justifies higher cost and memory headroom |
Compared with R7F100GLJ3CFB#AA0, the R7F100GMG3CFB#AA0 delivers 16 additional I/O pins and full 8×8 mutual capacitance support for richer HMI; versus R7F100GMK3CFB#AA0, it trades 128 KB flash and 8 KB RAM for lower BOM cost while retaining identical peripheral functionality and package compatibility.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GMG3CFB#AA0?
The R7F100GMG3CFB#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a single-supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy (at VDD = 1.8–5.5 V, TA = -20 to +85°C) ensures reliable timing for real-time control loops and communication interfaces without external crystals in many use cases.
Does the R7F100GMG3CFB#AA0 support capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMG3CFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix = 64 keys) configurations. It operates across the full VDD range of 1.8–5.5 V and includes hardware acceleration for noise immunity and automatic calibration, eliminating need for external touch controller ICs.
What low-power modes does the R7F100GMG3CFB#AA0 offer, and how does SNOOZE mode differ from STOP mode?
The R7F100GMG3CFB#AA0 offers HALT, STOP, and SNOOZE modes. STOP mode halts CPU and most peripherals with 0.23 µA typical current; SNOOZE mode keeps selected peripherals (e.g., CTSU2L, RTC, ADC) active while CPU remains asleep, enabling autonomous sensor polling or timed actions without wake-up latency or full-system restart overhead.
Can the R7F100GMG3CFB#AA0 perform background data flash rewriting, and what is the endurance specification?
Yes, the R7F100GMG3CFB#AA0 supports background operation (BGO) for data flash rewriting: application code executes from program memory while data flash is erased or programmed. The data flash endurance is rated at 1,000,000 write/erase cycles (typical), enabling robust parameter storage and field firmware updates without interrupting real-time operation.
What is the pin count, package type, and industrial temperature rating of the R7F100GMG3CFB#AA0?
The R7F100GMG3CFB#AA0 uses an 80-pin LFQFP package (12 × 12 mm, 0.50-mm pitch) with tray packaging (#AA0) and is rated for industrial ambient temperatures from -40°C to +105°C (C-grade marking), making it suitable for deployment in harsh environments such as factory automation, energy infrastructure, and outdoor equipment.
