Product details
Overview
R7F100GSL2DFB#HA0 from Renesas is an RL78/G23 128-pin, ultra-low-power 16-bit MCU with 384 KB code flash, 8 KB data flash, 32 KB RAM, 1.6–5.5 V operation, and integrated capacitive touch sensing (CTSU2L). It delivers 41 µA/MHz active current and 210 nA data retention, targeting battery-powered industrial HMI and sensor-edge nodes.
For engineers reviewing the R7F100GSL2DFB#HA0 datasheet, R7F100GSL2DFB#HA0 pinout, R7F100GSL2DFB#HA0 application, or R7F100GSL2DFB#HA0 equivalent, key selection criteria include its LFQFP-128 (0.50 mm pitch) package, -40 to +85°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L supporting up to 64 keys in mutual-capacitance matrix.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode), enabling dynamic power/performance scaling. It integrates a dedicated SNOOZE mode sequencer (SMS) that executes up to 32 preloaded commands-including ADC sampling, comparator evaluation, and CTSU2L scanning-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and dual-clock domains (high-speed on-chip oscillator ±1.0% accuracy, low-speed 32.768 kHz RTC oscillator) for precise timing isolation across sleep/wake states.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GSL3CFB#AA0 | Same 128-pin LFQFP package, but rated for -40 to +105°C industrial temp range and shipped in tray packaging | Required for extended-temperature deployments (e.g., under-hood automotive modules, outdoor utility meters) | Select when ambient operating temperature exceeds +85°C or tray-based assembly is preferred |
| R7F100GSK2DFB#HA0 | 256 KB code flash, 24 KB RAM, identical 128-pin LFQFP-0.50 mm package and pinout | Lower memory footprint suits cost-sensitive designs where 384 KB flash is unused; same peripheral set and power profile | Choose for BOM cost optimization where application firmware fits within 256 KB and no future flash expansion is planned |
Compared with R7F100GSL2DFB#HA0, the R7F100GSL3CFB#AA0 offers extended temperature capability at the cost of higher procurement minimums and tray-only packaging, while the R7F100GSK2DFB#HA0 reduces flash/RAM capacity by 33% without altering power behavior, pin compatibility, or peripheral functionality-making it ideal for footprint-locked cost-down paths.

FAQ
What is the maximum operating frequency and voltage range for the R7F100GSL2DFB#HA0?
The R7F100GSL2DFB#HA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a single-supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy over -20 to +85°C eliminates need for external crystals in many timing-critical applications, and the wide voltage range enables direct battery operation from single Li-ion or multi-cell alkaline sources without regulators.
Does the R7F100GSL2DFB#HA0 support hardware-accelerated capacitive touch sensing?
Yes, the R7F100GSL2DFB#HA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which provides hardware-accelerated self- and mutual-capacitance sensing. It supports up to 32 self-capacitance keys or an 8×8 mutual-capacitance matrix (64 keys), with built-in noise cancellation, auto-calibration, and low-power scanning-enabling robust touch performance even in noisy industrial environments without CPU overhead.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GSL2DFB#HA0?
The SNOOZE mode sequencer (SMS) in the R7F100GSL2DFB#HA0 executes up to 32 pre-programmed commands-including ADC conversions, CTSU2L scans, comparator evaluations, and register reads-entirely autonomously. It operates without waking the CPU, flash, or RAM, achieving sub-µA average current in periodic sensing tasks. This makes the R7F100GSL2DFB#HA0 uniquely suited for battery-powered devices requiring frequent but infrequent wake-ups, such as wireless sensor beacons.
What packaging and temperature grade does the R7F100GSL2DFB#HA0 use?
The R7F100GSL2DFB#HA0 uses a 128-pin LFQFP package with 0.50 mm pitch and is qualified for industrial temperature operation from -40°C to +85°C. Its #HA0 suffix indicates embossed tape packaging, compatible with high-volume automated assembly. The package includes exposed thermal pad recommendations and requires REGC decoupling (0.47–1 µF to VSS) per Renesas design guidelines.
Can the R7F100GSL2DFB#HA0 perform background data flash writes while executing code from main flash?
Yes, the R7F100GSL2DFB#HA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors-a critical capability for field firmware updates, parameter logging, and secure key storage without halting real-time application execution.
