Product details
Overview
R7F100GBF2DFP#AA0 from Renesas is a 32-pin LQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating at 1.6–5.5 V; it delivers 41 µA/MHz active current, 210 nA data retention, and integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and SNOOZE mode sequencer for ultra-low-power sensor and control applications.
For engineers reviewing the R7F100GBF2DFP#AA0 datasheet, R7F100GBF2DFP#AA0 pinout, R7F100GBF2DFP#AA0 application, or R7F100GBF2DFP#AA0 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm package, -40 to +85°C consumer-grade temperature range, integrated CTSU2L for up to 64-key touch panels, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R7F100GBF2DFP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode); it includes on-chip oscillators (32 MHz ±1.0%, 32.768 kHz adjustable) and dual voltage detectors (LVD0/LVD1) for robust power management.
Its peripheral set centers on low-power operation: the SNOOZE mode sequencer executes up to 32 preconfigured commands without CPU/RAM/flash activation; the Data Transfer Controller (DTC) enables chain transfers triggered by interrupts; and the Event Link Controller (ELCL) routes signals between peripherals like timers, ADC, and CTSU2L for autonomous event-driven processing.

The R7F100GBF2DFP#AA0 operates up to 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs; accuracy is ±1.0% over -20 to +85°C and VDD = 1.8–5.5 V. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep modes.
Does the R7F100GBF2DFP#AA0 support in-system programming and secure firmware updates?
Yes, the R7F100GBF2DFP#AA0 supports full in-system programming via on-chip debugging interface and includes flash shield window and block erase prohibition for security. Self-programming is enabled with boot swapping, allowing safe firmware updates without external programmers. Data flash supports background operation (BGO), enabling code execution during rewrites.
How many capacitive touch channels does the R7F100GBF2DFP#AA0 support, and what configurations are available?
The R7F100GBF2DFP#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It operates at VDD = 1.8–5.5 V and includes hardware noise cancellation. Pin assignments include P30 (TSCAP), P31, P50–P51, P60–P62, and P70–P72 - all configurable via dedicated CTSU registers.

The R7F100GBF2DFP#AA0 integrates UARTA (up to 6 channels), IICA (up to 10 channels), and SAU-based simplified SPI (up to 8 channels). On the 32-pin LQFP package, UARTA appears on P10–P15 (RxD0/TxD0, RxD2/TxD2), IICA on P60/P61 (SCLA0/SDAA0), and SAU on P10–P17 with flexible PIOR-based remapping - enabling protocol assignment to multiple pin groups without hardware change.
Is the R7F100GBF2DFP#AA0 pin-compatible with other RL78/G23 variants in the same package footprint?
Yes, all RL78/G23 devices in the 32-pin LQFP-0.8 mm package (e.g., R7F100GBG2DFP#AA0, R7F100GBH2DFP#AA0) share identical pinouts and electrical characteristics. Memory size differences (128 KB vs. 192 KB flash) and minor mask revisions do not affect pin function mapping, allowing drop-in replacement within the same package family for design scalability.
