Product details
Overview
R7F100GPH2DFA#AA0 from Renesas is a 100-pin, consumer-grade RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, 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 16-bit timer arrays - enabling battery-powered home appliance control panels.
For engineers reviewing the R7F100GPH2DFA#AA0 datasheet, R7F100GPH2DFA#AA0 pinout, R7F100GPH2DFA#AA0 application, or R7F100GPH2DFA#AA0 equivalent, key selection criteria include its LFQFP-100 package, -40°C to +85°C temperature grade, 128 KB flash/16 KB RAM configuration, and support for SNOOZE mode sequencer-driven low-power sensor polling without CPU wake-up.
Technical Context
The R7F100GPH2DFA#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting 32 sequential operations using 21 command types - enabling autonomous analog sensing and threshold comparison while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a 10-bit A/D converter (26 channels), two 8-bit D/A outputs, dual comparators with selectable internal/external reference, and flexible serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UARTA/LIN-capable UARTs, and 8 CSI (SPI-compatible) channels. The Logic and Event Link Controller (ELCL) enables hardware-triggered signal routing between peripherals without CPU intervention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPH3CFA#AA0 | Same 100-pin LFQFP package and 128 KB/16 KB memory, but industrial-grade (-40°C to +105°C) and higher VDD max (5.5 V vs. 5.5 V same), no functional difference in electrical specs | Targeted for HVAC control boards and factory automation where extended temperature range is required | Select when operating ambient exceeds +85°C or long-term reliability under thermal cycling is critical |
| R7F100GLH2DFA#AA0 | 64-pin LFQFP variant with identical 128 KB/16 KB memory, same voltage/power specs, but fewer I/O (52 vs. 72) and reduced peripheral count (e.g., only 4 I²C channels) | Suitable for space-constrained designs like smart plugs or compact IoT gateways where full 100-pin I/O is unnecessary | Choose to reduce PCB area and BOM cost when application uses ≤52 GPIOs and ≤4 serial interfaces |
Compared with R7F100GPH3CFA#AA0, the R7F100GPH2DFA#AA0 trades extended temperature rating for lower cost in consumer environments; compared with R7F100GLH2DFA#AA0, it provides 20+ additional GPIOs and enhanced peripheral concurrency - justifying the larger footprint in HMI-rich applications.

FAQ
What is the maximum operating frequency and voltage range for the R7F100GPH2DFA#AA0?
The R7F100GPH2DFA#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy) and supports a supply voltage range of 1.6 V to 5.5 V. This wide VDD range allows direct interfacing with 1.8-V, 3.3-V, and 5-V peripherals without level shifters, and the 32-MHz capability ensures sufficient processing headroom for real-time touch response and communication stack execution.
Does the R7F100GPH2DFA#AA0 support in-circuit debugging and flash programming?
Yes, the R7F100GPH2DFA#AA0 includes full on-chip debugging support via the on-chip debug emulator (OCDE) interface and enables self-programming of both code and data flash memory. It supports boot swapping and flash shield window protection, allowing secure firmware updates in the field without requiring external programmers - a key requirement for deployed consumer devices.
How many capacitive touch channels does the R7F100GPH2DFA#AA0 support, and what configurations are available?
The R7F100GPH2DFA#AA0 integrates the CTSU2L capacitive touch unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates across the full VDD range (1.8–5.5 V) and includes automatic drift compensation - enabling robust touch performance on plastic or glass overlays without recalibration during temperature shifts.
What serial communication interfaces are integrated into the R7F100GPH2DFA#AA0?
The R7F100GPH2DFA#AA0 integrates multiple serial interfaces: up to 10 channels of I²C/Simplified I²C, up to 6 UARTA channels (all LIN-bus compliant), and up to 8 CSI (SPI-compatible) channels. These are independently configurable and can operate concurrently - for example, one I²C channel can manage an OLED display while UARTA handles BLE module communication and CSI drives an external ADC.
Is the R7F100GPH2DFA#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 MCUs in the 100-pin LFQFP package (e.g., R7F100GPG2DFA#AA0, R7F100GPH2DFA#AA0, R7F100GPJ2DFA#AA0) share identical pinouts and electrical characteristics. Memory size differences (96–768 KB flash) and peripheral enablement are configured in software/fuse settings - enabling hardware reuse across product tiers with only firmware changes.
