Overview
R7F100GLN2DFA#AA0 from Renesas is a 64-pin, consumer-grade RL78/G23 16-bit microcontroller with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain operation for battery-powered home appliances and sensor nodes.
For engineers reviewing the R7F100GLN2DFA#AA0 datasheet, R7F100GLN2DFA#AA0 pinout, R7F100GLN2DFA#AA0 application, or R7F100GLN2DFA#AA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, STOP-mode wakeup latency < 4 µs, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch engine.
Technical Context
The R7F100GLN2DFA#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power architecture includes HALT, STOP, and SNOOZE modes-STOP enables sub-4 µs wakeup using dedicated interrupt sources, while SNOOZE mode sequencer executes up to 32 preconfigured commands without CPU involvement.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (24 channels), 8-bit DAC (2 channels), 2 comparators, 10-channel I²C/Simplified I²C, 6-channel UARTA (LIN-capable), and 8-channel CSI (SPI-compatible).

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLN2DFA#AA0?
The R7F100GLN2DFA#AA0 supports up to 32 MHz operation with high-speed on-chip oscillator accuracy of ±1.0% across VDD = 1.8–5.5 V and TA = −20°C to +85°C. At 1.6 V minimum supply, maximum frequency is reduced to 24 MHz per datasheet specifications. This dual-voltage/frequency scaling allows dynamic power/performance trade-offs in portable designs.
Does the R7F100GLN2DFA#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLN2DFA#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) modes. It includes built-in noise cancellation, automatic calibration, and programmable sensitivity-requiring no external RC components and enabling direct connection to touch electrodes.
How does the SNOOZE mode sequencer in the R7F100GLN2DFA#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GLN2DFA#AA0 executes up to 32 preloaded commands-including ADC conversions, comparisons, and GPIO toggles-without waking the CPU, flash, or RAM. This enables autonomous periodic sensing (e.g., temperature read every 30 seconds) at ~1 µA average current, cutting total system power by >90% compared to CPU-driven polling loops.
What are the data flash endurance and background operation capabilities of the R7F100GLN2DFA#AA0?
The R7F100GLN2DFA#AA0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical). It supports true background operation: the CPU can execute instructions from code flash while simultaneously rewriting data flash sectors, enabling reliable over-the-air parameter updates and logging without system interruption.
Which serial communication interfaces are available on the R7F100GLN2DFA#AA0, and how many channels does each support?
The R7F100GLN2DFA#AA0 integrates three serial interface families: up to 10 channels of I²C/Simplified I²C, up to 6 channels of UARTA (with LIN bus support), and up to 8 channels of CSI (SPI-compatible). All are hardware-accelerated with independent clock domains, FIFO buffers, and configurable polarity/phase-eliminating software bit-banging overhead.
