Product details
Overview
R7F100GGH3CFB#BA0 from Renesas is a 48-pin LFQFP-packaged 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 (up to 64 keys), and dual-clock domain operation supporting 32 MHz high-speed and 32.768 kHz low-power subsystem clocks for battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGH3CFB#BA0 datasheet, R7F100GGH3CFB#BA0 pinout, R7F100GGH3CFB#BA0 application, or R7F100GGH3CFB#BA0 equivalent, key selection considerations include its 48-pin LFQFP-0.5 mm pitch package, industrial-grade −40 to +105°C temperature rating (C-field), SNOOZE mode sequencer for autonomous low-power peripheral sequencing, and hardware-accelerated CTSU2L capacitive sensing unit with self/mutual capacitance support.
Technical Context
The R7F100GGH3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes-where the SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling, comparator comparison, timer trigger) without CPU, flash, or RAM activation.
Peripheral integration includes 8–26-channel 8/10/12-bit ADC with internal 1.48 V reference and temperature sensor, dual 8-bit DAC outputs (0–VDD), two comparators with selectable internal/external/DAC reference, and flexible serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UARTA/LIN-capable channels, and 8 CSI (SPI-compatible) channels-all configurable via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and clock source flexibility of the R7F100GGH3CFB#BA0?
The R7F100GGH3CFB#BA0 supports a maximum CPU operating frequency of 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy at VDD = 1.8–5.5 V, TA = −20 to +85°C). It also integrates selectable middle-speed (4/2/1 MHz) and low-speed (32.768 kHz) on-chip oscillators, plus external crystal support for X1/X2 pins-enabling precise RTC timing and flexible multi-domain clocking without external crystals in most use cases. The R7F100GGH3CFB#BA0 allows dynamic switching between clock sources during runtime.
Does the R7F100GGH3CFB#BA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGH3CFB#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 independent electrodes) and mutual-capacitance (8×8 matrix = 64 keys) configurations. It operates under VDD = 1.8–5.5 V, includes built-in noise cancellation, and requires no external components. Electrode assignment is configurable via dedicated CTSU registers, and touch detection can be triggered autonomously by the SNOOZE mode sequencer-enabling ultra-low-power wake-on-touch functionality without CPU involvement. The R7F100GGH3CFB#BA0 does not require external RC networks or dedicated touch controller ICs.
What are the data flash endurance and background operation capabilities of the R7F100GGH3CFB#BA0?
The R7F100GGH3CFB#BA0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical), with background operation (BGO) enabled-allowing full-speed program memory execution while simultaneously erasing or programming data flash sectors. This capability is essential for reliable field firmware updates, parameter storage with wear leveling, and secure key management. The R7F100GGH3CFB#BA0 supports flash shield window protection and boot swapping to ensure atomic update transitions without corruption risk during power loss.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GGH3CFB#BA0, and what operations can it perform autonomously?
The SNOOZE mode sequencer (SMS) in the R7F100GGH3CFB#BA0 executes up to 32 preloaded commands-including ADC conversions, comparator comparisons, timer starts/stops, GPIO toggles, and data transfers-without waking the CPU, flash, or RAM. It operates using only the low-speed subsystem clock (32.768 kHz), consuming microwatts of power. Commands are stored in dedicated SMS RAM and triggered by events like RTC alarms or external interrupts. This enables deterministic, ultra-low-power sensor polling, touch scanning, or status monitoring in the R7F100GGH3CFB#BA0-reducing system-level power by >95% compared to CPU-driven polling loops.
What industrial temperature and qualification standards apply to the R7F100GGH3CFB#BA0?
The R7F100GGH3CFB#BA0 is qualified for industrial ambient operating temperatures of −40 to +105°C (denoted by "C" in the ordering code), meeting AEC-Q100 stress test requirements for reliability in harsh environments. It is packaged in a 48-pin LFQFP (7 × 7 mm, 0.50-mm pitch) with lead-free, RoHS-compliant finish. The device includes dual voltage detectors (LVD0/LVD1), power-on-reset (POR), and watchdog timer-ensuring robust startup and fault recovery in factory automation, building controls, and motor drives where thermal cycling and electrical noise are prevalent. The R7F100GGH3CFB#BA0 is not automotive-qualified (AEC-Q100 Grade 2 or 1), but meets industrial-grade reliability benchmarks.
