It delivers ultra-low power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and SAU - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPG3CFB#BA0 datasheet, R7F100GPG3CFB#BA0 pinout, R7F100GPG3CFB#BA0 application, or R7F100GPG3CFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C operating range, CTSU2L support for up to 64 keys, and SNOOZE mode sequencer enabling CPU-free low-power periodic sensing.
Technical Context
The R7F100GPG3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 configurable commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and background operation (BGO) for concurrent code execution during data flash rewriting. The device uses a single 1.6–5.5 V supply with POR and dual voltage detectors (LVD0/LVD1).

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GPG3CFB#BA0?
The R7F100GPG3CFB#BA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 µs per instruction) for RTC and standby functions. Both modes are selectable via system clock configuration registers.
Does the R7F100GPG3CFB#BA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPG3CFB#BA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It operates across the full 1.8–5.5 V supply range and includes built-in noise cancellation, auto-calibration, and touch-detection interrupt generation - all without CPU intervention.
Can the R7F100GPG3CFB#BA0 perform data flash writes while executing code from main flash memory?
Yes, the R7F100GPG3CFB#BA0 supports Background Operation (BGO) for data flash. Instructions can be executed from code flash memory while simultaneously rewriting data flash memory. This enables seamless firmware parameter updates or data logging without halting real-time application execution - critical for uninterrupted industrial control loops.
What are the key low-power modes supported by the R7F100GPG3CFB#BA0, and what is the lowest achievable current draw?
The R7F100GPG3CFB#BA0 supports HALT, STOP, and SNOOZE modes. In STOP mode, current drops to 210 nA with 4 KB RAM retention. SNOOZE mode enables peripheral-initiated processing (e.g., ADC sampling, comparison) without CPU wake-up, achieving sub-µA average current in duty-cycled sensor applications. Active-mode current is 41 µA/MHz at 32 MHz.
Is the R7F100GPG3CFB#BA0 pin-compatible with other RL78/G23 variants in the same 100-pin LFQFP package?
Yes, all RL78/G23 devices in the 100-pin LFQFP package (e.g., R7F100GPJ3CFB#BA0, R7F100GPL3CFB#BA0) share identical pinouts and electrical characteristics. Memory size, peripheral enablement, and some feature flags differ by part number, but PCB layout, power delivery, and signal routing remain fully compatible across the 100-pin family.
