Product details
Overview
R7F100GMN3CFA#BA0 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), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain support for real-time control in battery-powered HMI and sensor nodes.
For engineers reviewing the R7F100GMN3CFA#BA0 datasheet, R7F100GMN3CFA#BA0 pinout, R7F100GMN3CFA#BA0 application, or R7F100GMN3CFA#BA0 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-accelerated CTSU2L capacitive touch engine.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMN3CFA#BA0?
The R7F100GMN3CFA#BA0 supports up to 32 MHz operation 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 ±1.0% oscillator accuracy (VDD = 1.8–5.5 V, TA = -20 to +85°C) ensures reliable timing without external crystals in many cost-sensitive designs.
Does the R7F100GMN3CFA#BA0 support hardware debugging, and what interface is used?
Yes, the R7F100GMN3CFA#BA0 supports on-chip debugging via the single-pin SWD (Serial Wire Debug) interface using the TOOL0 pin (P40). This enables full breakpoint, watchpoint, and memory access capabilities through standard Renesas E2 or E2 Lite debuggers, with no dedicated debug header required - simplifying board layout and reducing connector count.
How many capacitive touch channels does the R7F100GMN3CFA#BA0 support, and what configurations are available?
The R7F100GMN3CFA#BA0 integrates the CTSU2L capacitive touch unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates at VDD = 1.8–5.5 V and includes hardware noise cancellation, automatic drift compensation, and programmable sensitivity - enabling robust touch performance in electrically noisy industrial environments.
What is the purpose of the SNOOZE mode sequencer (SMS) in the R7F100GMN3CFA#BA0, and how does it reduce system power?
The SNOOZE mode sequencer (SMS) in the R7F100GMN3CFA#BA0 executes up to 32 predefined operations - such as ADC conversions, timer comparisons, or GPIO toggles - autonomously without CPU, flash, or RAM involvement. By offloading periodic sensing tasks from firmware, SMS enables extended STOP-mode residency, achieving sub-µA average system current in duty-cycled sensor applications.
Can the R7F100GMN3CFA#BA0 perform simultaneous data flash writes and program execution, and what is the endurance rating?
Yes, the R7F100GMN3CFA#BA0 supports Background Operation (BGO) for data flash, allowing full-speed code execution from program memory while rewriting the 8 KB data flash. Its data flash is rated for 1,000,000 write/erase cycles (typical), enabling reliable logging, parameter storage, and field firmware updates without wear-leveling overhead in the application layer.
