Product details
Overview
R7F100GLH2DFB#BA0 from Renesas is a 64-pin LFQFP, 5.0-V tolerant RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 to 5.5 V at -40 to +85°C. It integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA, IICA, and CSI - deployed in industrial HMI control panels requiring ultra-low power and robust touch interface.
For engineers reviewing the R7F100GLH2DFB#BA0 datasheet, R7F100GLH2DFB#BA0 pinout, R7F100GLH2DFB#BA0 application, or R7F100GLH2DFB#BA0 equivalent, key selection criteria include its 192 KB flash/20 KB RAM configuration, 64-pin LFQFP-0.5 mm package, STOP-mode wakeup time < 4 µs, 41 µA/MHz active current, and CTSU2L-based capacitive sensing support for touch-enabled embedded systems.
Technical Context
The R7F100GLH2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It features SNOOZE mode sequencer (SMS) with 32 programmable steps and 21 command types for autonomous low-power peripheral sequencing without CPU involvement.
Its peripheral set includes ELCL for event-driven logic routing between modules, DTC for interrupt-triggered memory transfers, and CTSU2L supporting both self- and mutual-capacitance sensing - enabling hardware-accelerated touch detection while maintaining HALT/STOP current as low as 210 nA (4 KB RAM retention).

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLH2DFB#BA0?
The R7F100GLH2DFB#BA0 supports up to 32 MHz operation with the high-speed on-chip oscillator (±1.0% accuracy) across VDD = 1.8–5.5 V. At 1.6 V minimum supply, maximum frequency is reduced to 24 MHz per electrical specifications. All timing parameters in the datasheet assume operation within these validated voltage-frequency envelopes.
Does the R7F100GLH2DFB#BA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLH2DFB#BA0 integrates the CTSU2L 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 operates across VDD = 1.8–5.5 V, includes built-in noise cancellation, and requires no external components beyond standard decoupling - all managed entirely in hardware without CPU intervention.
What are the memory protection and security features implemented in the R7F100GLH2DFB#BA0?
The R7F100GLH2DFB#BA0 provides flash block erase/write prohibition, on-chip debugging lock, and flash shield window for secure bootloader partitioning. It supports self-programming with boot swapping but lacks AES encryption engines or secure key storage - making it suitable for basic IP protection rather than cryptographic-grade security applications.
Can the R7F100GLH2DFB#BA0 operate from a single 3.3 V supply while interfacing with 5 V peripherals?
Yes, the R7F100GLH2DFB#BA0 operates from 1.6–5.5 V and features 5.0 V-tolerant I/O pins including P60/P61 (I²C), P10–P17 (serial), and P30/P31 (touch). When VDD ≥ 2.7 V, these pins accept 0–5.0 V signals directly - eliminating level shifters in mixed-voltage systems such as 3.3 V MCU + 5 V display or sensor interfaces.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GLH2DFB#BA0, and what is its practical power benefit?
The SMS in the R7F100GLH2DFB#BA0 executes up to 32 preloaded commands (e.g., ADC start, wait, read, compare) autonomously - waking only the required peripheral while keeping CPU, flash, and RAM powered down. In a typical touch-scan + temperature-read cycle, this reduces average current from ~200 µA (CPU-active) to < 15 µA, extending coin-cell battery life by 10× compared to polling-based implementations.
