Product details
Overview
R7F100GBG2DNP#AA0 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 at 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit timers, 12-bit ADC (26 channels), and dual DAC outputs - deployed in battery-powered consumer HMI and sensor interface applications.
For engineers reviewing the R7F100GBG2DNP#AA0 datasheet, R7F100GBG2DNP#AA0 pinout, R7F100GBG2DNP#AA0 application, or R7F100GBG2DNP#AA0 equivalent, key selection criteria include its HWQFN-32 package, -40°C to +85°C temperature grade, integrated SNOOZE mode sequencer for autonomous low-power operation, and support for UARTA/LIN, IICA, and simplified SPI interfaces.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/accumulate instructions and 1 MB address space.
Power management includes HALT, STOP, and SNOOZE modes; the latter enables up to 32 sequential low-power operations using 21 built-in commands without CPU, flash, or RAM activation. Peripheral event linking (ELCL) allows hardware-level signal routing between functions like timers, ADC, and communication units.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GBG2DNP#AA0?
The R7F100GBG2DNP#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 µs instruction time) for RTC and deep-sleep sequencing - all within the same voltage window.
Does the R7F100GBG2DNP#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GBG2DNP#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports self-capacitance mode (up to 32 independent electrodes) and mutual-capacitance matrix mode (8 × 8 = 64 keys) - both operating under VDD = 1.8–5.5 V. Electrode configuration uses dedicated CCD pins (CCD00–CCD06), and touch processing can run autonomously in SNOOZE mode without CPU intervention.
What communication interfaces are available on the R7F100GBG2DNP#AA0, and how many instances does each support?
The R7F100GBG2DNP#AA0 provides UARTA (LIN-compatible, 3 channels), simplified SPI (CSI, 3 channels), and IICA (I²C-compatible, 4 channels). All are implemented in the Serial Array Unit (SAU) and share flexible pin mapping via PIOR register. No dedicated CAN, USB, or Ethernet interfaces are present - communication is optimized for low-pin-count, low-power sensor and HMI connectivity.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GBG2DNP#AA0, and what tasks can it perform autonomously?
The SNOOZE mode sequencer in the R7F100GBG2DNP#AA0 executes up to 32 pre-programmed commands (e.g., ADC conversion, value comparison, timer wait, GPIO toggle) without waking the CPU, flash, or RAM. It operates using only the 32.768 kHz subsystem clock and draws sub-microamp current. Typical use cases include periodic sensor sampling, threshold-triggered wake-up, and low-power LED blinking sequences - all fully autonomous.
What is the data flash endurance and background operation capability of the R7F100GBG2DNP#AA0?
The R7F100GBG2DNP#AA0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical). It supports Background Operation (BGO), enabling concurrent code execution from program memory while data flash is being rewritten - essential for over-the-air updates, field calibration storage, and nonvolatile parameter logging without system interruption.
