Product details
Overview
R7F100GFH2DFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +85°C. It integrates capacitive touch sensing (CTSU2L), 10-bit ADC (26 channels), dual DAC, RTC, UARTA/IICA/SAU interfaces, and ultra-low-power STOP/SNOOZE modes - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GFH2DFP#HA0 datasheet, R7F100GFH2DFP#HA0 pinout, R7F100GFH2DFP#HA0 application, or R7F100GFH2DFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 128 KB flash/16 KB RAM memory configuration, CTSU2L-based touch interface support, and verified SNOOZE mode sequencer for autonomous low-power sensor polling without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/MAC instructions and 1 MB address space with four register banks.
Power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer executing up to 32 preloaded commands (e.g., ADC sampling, comparison, GPIO toggle) without CPU, flash, or RAM activation. The ELCL logic controller enables event-driven peripheral chaining independent of software intervention.

Pinout & Package
Package: 44-pin plastic LQFP (10 × 10 mm, 0.80-mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | ADC input / UARTA TX / timer input | Primary serial transmit pin for UARTA channel 1; also serves as 10-bit ADC channel ANI17 and TI00 timer input |

FAQ
What is the maximum operating frequency and associated current consumption for R7F100GFH2DFP#HA0?
R7F100GFH2DFP#HA0 operates up to 32 MHz using the high-speed on-chip oscillator (±1.0% accuracy). At this frequency and VDD = 3.3 V, typical active current is 41 µA/MHz - resulting in ~1.3 mA total at full speed. STOP mode current drops to 210 nA with 4 KB RAM retention, confirmed per datasheet Section 1.1.
Does R7F100GFH2DFP#HA0 support hardware-based capacitive touch sensing without external components?
Yes, R7F100GFH2DFP#HA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) at VDD = 1.8–5.5 V. No external RC networks or dedicated touch ICs are required - all signal processing is handled in hardware with minimal CPU intervention.
What debug interface does R7F100GFH2DFP#HA0 use, and which pins are dedicated to it?
R7F100GFH2DFP#HA0 uses the on-chip debug interface accessible via dedicated TOOL0 (pin 5), TOOLRxD (P11), and TOOLTxD (P12) pins. These support full SWD-style debugging including halt/run control, breakpoint setting, and memory inspection - no external JTAG adapter is needed.
Can R7F100GFH2DFP#HA0 execute code while rewriting data flash memory?
Yes, R7F100GFH2DFP#HA0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash while data flash is being rewritten - enabling uninterrupted real-time operation during parameter updates, calibration storage, or firmware patching.
What is the function of the REGC pin on R7F100GFH2DFP#HA0, and what happens if it is left unconnected?
The REGC pin on R7F100GFH2DFP#HA0 is the internal voltage regulator bypass terminal and must be connected to VSS via a 0.47–1 µF ceramic capacitor. Leaving it unconnected destabilizes the internal regulator, causing unpredictable resets, flash write failures, or complete functional lockup - per datasheet Caution in Section 1.3.4.
