Product details
Overview
R7F100GAH2DSP#AA0 from Renesas is an RL78/G23 32-bit ultra-low-power MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It features a 32-MHz high-accuracy on-chip oscillator (±1.0%), 16-bit timer array (16 channels), 12-bit A/D converter (26 channels), capacitive touch sensing unit (CTSU2L), and integrated UARTA/IICA/SAU interfaces - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GAH2DSP#AA0 datasheet, R7F100GAH2DSP#AA0 pinout, R7F100GAH2DSP#AA0 application, or R7F100GAH2DSP#AA0 equivalent, this page delivers verified electrical specs, package mapping to 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch), SNOOZE mode sequencer operation, and real-world use cases for low-duty-cycle embedded control.
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). It supports multiply/divide/MAC instructions and 1 MB address space.
Power management includes HALT, STOP, and SNOOZE modes - enabling 41 µA/MHz active current and 210 nA data retention (4 KB RAM). The SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without CPU, flash, or RAM activation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 32-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained firmware. |
| Operating Voltage | 1.6–5.5 V - supports direct connection to single-cell Li-ion (3.0–4.2 V), 3.3-V logic, or 5-V legacy peripherals without level shifters. |
| Flash/RAM | 128 KB code flash + 8 KB data flash + 16 KB RAM - sufficient for OTA-capable firmware with secure boot and parameter logging. |
| A/D Converter | 12-bit resolution, 26 input channels, internal 1.48-V reference - enables precision analog monitoring of sensors, power rails, and thermistors. |
| Capacitive Sensing | CTSU2L unit supporting self-capacitance (32 keys) or mutual capacitance (8×8 matrix) - eliminates external touch controller ICs in HMI designs. |
| Low-Power Modes | STOP mode with 210-nA RAM retention (4 KB); SNOOZE sequencer wakes peripherals autonomously - extends battery life in intermittent-sensing applications. |
| Timers & RTC | 16-channel 16-bit TAU, 1-channel 32-bit interval timer, and full-featured RTC (alarm, correction, 1-sec to 99-year counting) - replaces discrete real-time clock ICs. |
Pinout & Package
Package: 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch), exposed die pad (recommended to connect to VSS), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10 | SCK00/SCL00 (IICA) | Primary I²C clock line; supports standard/fast-mode (100/400 kHz) for sensor and EEPROM communication. |
| P11 | SI00/RxD0 (UARTA) | Primary UART receive input; TTL-level compatible, supports LIN-bus framing when configured as UARTA. |
| P12 | SO00/TxD0 (UARTA) | Primary UART transmit output; drives 3.3-V logic levels directly; supports auto-baud detection in LIN mode. |
| P147 | ANI18/IVCMP0 | Analog input channel 18 or comparator 0 input; enables voltage threshold detection without CPU intervention. |
| P30 | TSCAP/RTC1HZ | Dedicated capacitive sensing input pin and 1-Hz RTC output - simplifies touch button design and timekeeping signal routing. |
| P50 | TS00/SI11/SDA11 | Touch sense input 0, SAU channel 11 serial input, or IICA data line - multiplexed for flexible peripheral assignment. |
| REGC | Regulator capacitor terminal | Must be connected to VSS via 0.47–1 µF capacitor; stabilizes internal LDO for consistent low-power operation. |
| VDD / VSS | Power supply / Ground | Single 1.6–5.5 V supply; VSS must connect to exposed die pad for thermal and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes 32-step command sequences (ADC sampling, compare, GPIO toggle) autonomously - reduces wake-up latency and CPU load in periodic sensing. |
| Capacitive Touch Sensing Unit (CTSU2L) | Supports both self- and mutual-capacitance configurations; integrates hardware-based noise cancellation - enables robust touch buttons/sliders without firmware filtering. |
| Data Flash with Background Operation (BGO) | 8 KB data flash allows concurrent program execution and nonvolatile parameter updates - critical for field-upgradable calibration data and device configuration. |
| ELCL Event Link Controller | Hardware routing of peripheral events (e.g., timer overflow → ADC trigger → DMA request) - eliminates software polling and interrupt nesting overhead. |
| High-Accuracy On-Chip Oscillator | ±1.0% over -20 to +85°C (VDD = 1.8–5.5 V); eliminates external crystal for UART/LIN timing - reduces BOM cost and PCB area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GBH2DNP | Same 32-pin HWQFN package, identical 128 KB/16 KB memory, but rated for industrial temp (-40 to +105°C) and uses different packaging spec (#DNP vs #AA0). | Required for designs operating above +85°C ambient (e.g., enclosed motor drives, outdoor enclosures). | Select R7F100GBH2DNP when extended temperature range or tape-and-reel packaging is mandatory for automated assembly. |
| R7F100GAJ2DSP | Same consumer-grade rating (-40 to +85°C) and 32-pin LQFP (7 × 7 mm, 0.8-mm pitch) package, but with 192 KB flash and 20 KB RAM. | Suitable when firmware growth exceeds 128 KB or additional RAM is needed for protocol stacks (e.g., BLE mesh, Modbus TCP). | Choose R7F100GAJ2DSP only if memory headroom is critical and LQFP layout compatibility exists; no pin-to-pin match with HWQFN. |
Compared with R7F100GAH2DSP#AA0, R7F100GBH2DNP offers guaranteed operation up to +105°C but requires requalification for thermal management, while R7F100GAJ2DSP provides 64 KB more flash at the cost of larger footprint and no mechanical interchangeability.

The R7F100GAH2DSP#AA0 features a high-speed on-chip oscillator selectable up to 32 MHz with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = -20 to +85°C. This eliminates need for external crystals in UART, LIN, and I²C timing-critical applications while maintaining reliable communication baud rates.
Does R7F100GAH2DSP#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, R7F100GAH2DSP#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It includes hardware noise cancellation and automatic drift compensation - enabling robust touch interfaces without external components or intensive firmware processing.
What low-power modes are available in R7F100GAH2DSP#AA0, and what is the lowest current draw?
R7F100GAH2DSP#AA0 supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, it draws 210 nA - verified at VDD = 3.0 V and TA = 25°C. SNOOZE mode enables autonomous peripheral operation (e.g., ADC sampling, comparisons) at ~1.5 µA, extending battery life in intermittent-sensing applications.
Can R7F100GAH2DSP#AA0 execute code while rewriting data flash memory?
Yes, R7F100GAH2DSP#AA0 supports Background Operation (BGO) for its 8 KB data flash. Instructions can be fetched and executed from code flash while data flash is being rewritten - enabling seamless parameter updates, calibration storage, or firmware configuration changes without halting real-time tasks.
What is the pin count and package type of R7F100GAH2DSP#AA0, and is the exposed pad required?
R7F100GAH2DSP#AA0 uses a 32-pin HWQFN package (5 × 5 mm, 0.50-mm pitch) with an exposed die pad. Renesas recommends connecting the exposed pad to VSS for optimal thermal dissipation and reduced ground noise - especially critical in analog and low-power operation where stability affects ADC and CTSU2L performance.
