Product details
Overview
R7F100GMN3CFB#HA0 from Renesas is an RL78/G23 80-pin ultra-low-power 16-bit MCU with 768 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It integrates a capacitive touch sensing unit (CTSU2L), 16-bit TAU timers (up to 16 channels), RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), targeting industrial HMI and sensor-edge control applications.
For engineers reviewing the R7F100GMN3CFB#HA0 datasheet, R7F100GMN3CFB#HA0 pinout, R7F100GMN3CFB#HA0 application, or R7F100GMN3CFB#HA0 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GMN3CFB#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling 32-step autonomous sequenced operations using 21 command types while keeping CPU, flash, and RAM inactive.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELCL) routes signals between peripherals (e.g., ADC trigger → timer → DMA), while the Data Transfer Controller (DTC) supports chain transfer across up to 32 sources/destinations. The CTSU2L supports both self-capacitance (32 keys) and mutual capacitance (8×8 matrix) touch sensing under VDD = 1.8–5.5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GML3CFB#HA0 | Same 80-pin LFQFP package, but 512 KB code flash, 48 KB RAM, 8 KB data flash | Lower memory footprint suits simpler control tasks without extensive firmware or data logging | Select when application firmware size remains below 512 KB and cost optimization is prioritized |
| R7F100GMK3CFB#HA0 | Same 80-pin LFQFP package, 384 KB code flash, 32 KB RAM, 8 KB data flash | Reduced RAM limits concurrent peripheral buffering; suitable for basic real-time control without complex UI or comms stacks | Choose for cost-sensitive industrial controllers where 32 KB RAM suffices for task scheduling and protocol buffers |
Compared with R7F100GMN3CFB#HA0, the R7F100GML3CFB#HA0 offers identical package and peripheral set with 256 KB less flash - ideal for firmware-stable deployments - while R7F100GMK3CFB#HA0 trades 16 KB RAM and 384 KB flash for lower unit cost, constraining multitasking depth and feature scalability.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMN3CFB#HA0?
The R7F100GMN3CFB#HA0 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 maintains operation down to 1.6 V, enabling compatibility with single-cell Li-ion or multi-cell alkaline supplies without regulators.
Does the R7F100GMN3CFB#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMN3CFB#HA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on individual pins) and mutual capacitance (8×8 matrix, up to 64 keys) configurations. It operates under VDD = 1.8–5.5 V, includes built-in noise cancellation, and requires no external components beyond standard PCB layout practices for touch electrodes.
How many serial communication interfaces does the R7F100GMN3CFB#HA0 provide, and which protocols are supported?
The R7F100GMN3CFB#HA0 provides up to 6 UARTA channels (with LIN-bus support), 10 IICA channels (I²C-compatible master/slave), and 8 CSI channels (SPI-compatible). It also includes one remote control signal receiver (REMC) for infrared waveform pattern matching. All interfaces are independently configurable and support hardware flow control and automatic baud rate detection where applicable.
What power-saving modes are available on the R7F100GMN3CFB#HA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GMN3CFB#HA0 supports HALT, STOP, and SNOOZE modes. STOP mode disables CPU, flash, and RAM clocks (210 nA retention). SNOOZE mode keeps only the SMS sequencer, selected peripherals (e.g., ADC, timers), and dedicated RAM active - enabling autonomous 32-step sequences (e.g., sample → compare → flag) without CPU involvement or flash/RAM power, achieving sub-µA average current in periodic sensing.
Is the R7F100GMN3CFB#HA0 pin-compatible with other RL78/G23 variants in the same 80-pin LFQFP package?
Yes, all RL78/G23 devices in the 80-pin LFQFP-0.5mm package (e.g., R7F100GML3CFB#HA0, R7F100GMK3CFB#HA0) share identical pinouts and electrical characteristics. This allows drop-in replacement across memory variants - firmware and PCB remain unchanged when scaling flash/RAM capacity based on application requirements.
