Product details
Overview
R7F100GBH2DFP#AA0 from Renesas is a 32-bit RL78/G23 microcontroller 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), integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, and dual UART/I²C/SPI interfaces - deployed in battery-powered industrial sensor nodes and smart home control panels.
For engineers reviewing the R7F100GBH2DFP#AA0 datasheet, R7F100GBH2DFP#AA0 pinout, R7F100GBH2DFP#AA0 application, or R7F100GBH2DFP#AA0 equivalent, key selection criteria include its LQFP-32 package, -40°C to +85°C consumer-grade temperature range, integrated CTSU2L for up to 64-key mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-free low-power periodic sensing.
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/accumulate instructions and 1 MB address space, enabling deterministic real-time control in resource-constrained edge devices.
Power management includes HALT, STOP, and SNOOZE modes - the latter using a dedicated sequencer executing up to 32 preconfigured commands (e.g., ADC sampling, CTSU scan, register comparison) without CPU, flash, or RAM activation. The ELCL enables event-driven peripheral chaining, eliminating software polling overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GBG2DFP#AA0 | Same 32-pin LQFP package and 128 KB flash, but 12 KB RAM (vs. 16 KB) and no CTSU2L support | Lacks capacitive touch capability; suitable only for non-touch control applications | Select when touch interface is unnecessary and BOM cost reduction is prioritized over future UI expansion |
| R7F100GBJ2DFP#AA0 | Same package and CTSU2L, but 192 KB flash and 20 KB RAM - higher memory footprint and $0.32 higher unit cost | Enables larger firmware (e.g., embedded TLS stack) and extended data logging buffers | Choose when firmware complexity exceeds 128 KB or >16 KB RAM is needed for real-time analytics |
Compared with R7F100GBH2DFP#AA0, R7F100GBG2DFP#AA0 sacrifices touch capability and RAM for lower cost, while R7F100GBJ2DFP#AA0 trades higher price for scalable memory - making R7F100GBH2DFP#AA0 the optimal balance for touch-enabled, battery-operated edge controllers with moderate firmware size.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GBH2DFP#AA0?
The R7F100GBH2DFP#AA0 operates up to 32 MHz using its 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 ~1.31 mA total. In STOP mode, current drops to 0.34 µA, and data retention in 16 KB RAM consumes just 210 nA.
Does the R7F100GBH2DFP#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GBH2DFP#AA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, TRNG). It relies on software libraries for encryption. For secure boot or TLS offload, designers should consider Renesas' RA-family MCUs with TrustZone or Crypto Acceleration Engine - the R7F100GBH2DFP#AA0 prioritizes ultra-low power and analog integration over crypto throughput.
Can the R7F100GBH2DFP#AA0's CTSU2L unit drive mutual-capacitance touch panels with more than 8×8 electrodes?
No - the CTSU2L unit in the R7F100GBH2DFP#AA0 supports a maximum of 8 transmit and 8 receive channels, limiting mutual-capacitance matrices to 8×8 = 64 keys. Larger touch surfaces require external touch controllers or migration to RL78/G23 variants with expanded CTSU (e.g., R7F100GLN3CFB with 16×16 support). The R7F100GBH2DFP#AA0's CTSU2L is optimized for compact UIs like thermostat sliders or appliance control pads.
What debug interfaces are available on the R7F100GBH2DFP#AA0, and are they accessible in all power modes?
The R7F100GBH2DFP#AA0 supports on-chip debugging via SWD (Serial Wire Debug) using pins P40 (TOOL0) and P11/P12 (TOOLRxD/TOOLTxD). Debug access is available in HALT and RUN modes but disabled in STOP and SNOOZE modes to preserve ultra-low power integrity. Breakpoints, watchpoints, and memory inspection remain fully functional during active debugging sessions on the R7F100GBH2DFP#AA0.
Is the R7F100GBH2DFP#AA0 pin-compatible with other RL78/G23 variants in the same 32-pin LQFP package?
Yes - all RL78/G23 32-pin LQFP variants (e.g., R7F100GBF2DFP#AA0, R7F100GBG2DFP#AA0, R7F100GBJ2DFP#AA0) share identical pinouts and electrical characteristics. Firmware portability is ensured across memory variants; only flash/RAM/CTSU availability differs. This enables seamless BOM upgrades (e.g., from 96 KB to 128 KB flash) without PCB redesign - a key advantage of the R7F100GBH2DFP#AA0's family-consistent packaging.
