Product details
Overview
R7F100GBH2DNP#BA0 from Renesas is a 32-pin 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. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and hardware SNOOZE mode sequencer for autonomous low-power operation in battery-powered HMI and sensor nodes.
For engineers reviewing the R7F100GBH2DNP#BA0 datasheet, R7F100GBH2DNP#BA0 pinout, R7F100GBH2DNP#BA0 application, or R7F100GBH2DNP#BA0 equivalent, key selection considerations include its HWQFN-32 package, consumer-grade temperature range (−40 to +85°C), 32.768-kHz RTC accuracy, CTSU2L self/mutual capacitance support, and SNOOZE mode sequencer command set for interrupt-free 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; 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/accumulate operations. Its memory subsystem includes 128 KB code flash with 2 KB block erase, 8 KB background-operable data flash (1M rewrite cycles), and 16 KB SRAM with 210-nA retention current.
Peripheral integration centers on autonomous low-power operation: the SNOOZE mode sequencer executes up to 32 preconfigured commands (including ADC sampling, comparator comparison, and CTSU2L scanning) without CPU wake-up; the ELCL enables event-driven peripheral chaining; and the DTC handles DMA transfers triggered by 32+ interrupt sources-including timer overflows, UART reception, and CTSU2L completion-reducing CPU load during sensor acquisition.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GBH2DNP#BA0?
The R7F100GBH2DNP#BA0 operates up to 32 MHz using the high-speed on-chip oscillator with ±1.0% accuracy. At this frequency and VDD = 3.3 V, typical active current is 41 µA per MHz - resulting in ~1.3 mA total at full speed. This enables responsive real-time control while maintaining ultra-low power efficiency for intermittent operation.
Does the R7F100GBH2DNP#BA0 support hardware debugging, and what interface is used?
Yes, the R7F100GBH2DNP#BA0 supports on-chip debugging via the on-chip debug emulator (OCDE) using the TOOL0, TOOLRxD, and TOOLTxD pins. These map to a 3-wire SWD-compatible interface that enables full breakpoint, step-through, and memory inspection capabilities without requiring additional debug headers or external JTAG adapters.
Can the R7F100GBH2DNP#BA0 drive capacitive touch buttons directly, and how many are supported?
Yes, the R7F100GBH2DNP#BA0 integrates the CTSU2L capacitive sensing unit and supports up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix) without external components. Pin assignments like P30 (TSCAP), P50–P51, P60–P62, and P70–P72 are dedicated CTSU2L channels, enabling robust touch detection in noisy environments.
What are the RTC accuracy specifications and calibration options for the R7F100GBH2DNP#BA0?
The R7F100GBH2DNP#BA0 RTC uses the 32.768 kHz low-speed on-chip oscillator or an external crystal. With internal oscillator, RTC accuracy is ±125 ppm over −40 to +85°C; with external 32.768 kHz crystal, accuracy improves to ±20 ppm. The device includes hardware clock correction circuitry allowing software-adjusted compensation for crystal aging or temperature drift.
How does the SNOOZE mode sequencer (SMS) reduce power in the R7F100GBH2DNP#BA0?
The SNOOZE mode sequencer in the R7F100GBH2DNP#BA0 executes up to 32 preloaded commands - including ADC conversions, comparator comparisons, CTSU2L scans, and register reads - without waking the CPU, flash, or RAM. This reduces average system power by eliminating polling loops and enables true autonomous sensing intervals (e.g., 1-second touch scan) at sub-µA quiescent current.
