Product details
Overview
R7F100GMN3CFA#HA0 from Renesas is an RL78/G23 80-pin industrial-grade 16-bit MCU with 768 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (up to 64 keys), a 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces - deployed in battery-powered industrial HMI and sensor edge nodes.
For engineers reviewing the R7F100GMN3CFA#HA0 datasheet, R7F100GMN3CFA#HA0 pinout, R7F100GMN3CFA#HA0 application, or R7F100GMN3CFA#HA0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/accumulate instructions and 1 MB address space with four register banks.
Power management includes HALT, STOP, and SNOOZE modes; the latter uses a dedicated sequencer executing up to 32 preconfigured commands (from 21 available) to perform analog sensing, comparisons, and peripheral control while keeping CPU, flash, and RAM powered down - enabling microamp-level background operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLN3CFA#HA0 | Same 80-pin LQFP-0.65mm package, but 512 KB code flash / 48 KB RAM / 8 KB data flash | Lower code density suits simpler control firmware without extensive GUI or protocol stacks | Select when application firmware fits ≤512 KB and cost optimization is prioritized over future feature scalability |
| R7F100GMN3CFB#HA0 | Same memory (768 KB/48 KB/8 KB) and core, but 80-pin LFQFP-0.50mm (12×12 mm) package with different thermal pad layout | Smaller footprint and improved thermal dissipation; requires PCB redesign due to pitch and pad differences | Choose for space-constrained designs where 0.5-mm pitch assembly is supported and thermal performance is critical |
Compared with R7F100GLN3CFA#HA0, the R7F100GMN3CFA#HA0 provides 256 KB additional code flash for complex protocol stacks or OTA update partitions; versus R7F100GMN3CFB#HA0, it offers identical functionality but in a larger, more manufacturable 0.65-mm pitch LQFP package suitable for standard SMT lines.

FAQ
What is the maximum operating frequency and associated current consumption of the R7F100GMN3CFA#HA0?
The R7F100GMN3CFA#HA0 operates up to 32 MHz using the high-speed on-chip oscillator with ±1.0% accuracy. At this frequency and 3.3 V supply, typical active current is 41 µA per MHz - resulting in ~1.31 mA total at full speed. In STOP mode, current drops to 320 nA (typ.) with RTC and 4 KB RAM retention enabled.
Does the R7F100GMN3CFA#HA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GMN3CFA#HA0 integrates the CTSU2L capacitive sensing unit capable of self-capacitance (32 keys) or mutual-capacitance (64-key 8×8 matrix) operation. It requires no external RC networks or dedicated touch controller ICs - only calibrated electrode layout and firmware configuration of CTSU registers.
How does the SNOOZE mode sequencer in the R7F100GMN3CFA#HA0 reduce system power versus conventional sleep modes?
The SNOOZE mode sequencer in the R7F100GMN3CFA#HA0 executes predefined command sequences (e.g., "start ADC → wait EOC → store result → compare → set flag") autonomously - without waking the CPU, accessing flash, or powering RAM. This achieves sustained sub-µA background operation, unlike HALT/STOP modes that require full wake-up for any processing.
Can the R7F100GMN3CFA#HA0 perform simultaneous background data flash writes while executing application code?
Yes, the R7F100GMN3CFA#HA0 supports Background Operation (BGO) for its 8 KB data flash. Application code continues executing from main program memory while data flash sectors are erased and rewritten - enabling real-time logging, parameter updates, and secure firmware patching without interrupting control loops.
What debug and programming interfaces are supported by the R7F100GMN3CFA#HA0?
The R7F100GMN3CFA#HA0 supports on-chip debugging via the single-pin SWD interface (using P40/TOOL0) and full-featured emulation through the Renesas E2 emulator. It also enables self-programming of code and data flash with boot swapping and flash shield window protection - all accessible via standard Renesas CS+ or e2 studio IDEs.
