Product details
Overview
R7F100GGN3CNP#AA0 from Renesas is an RL78/G23 48-pin HWQFN microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +105°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (up to 16 channels), UARTA/IICA/SAU interfaces, and ultra-low-power STOP mode (210 nA RAM retention).
For engineers reviewing the R7F100GGN3CNP#AA0 datasheet, R7F100GGN3CNP#AA0 pinout, R7F100GGN3CNP#AA0 application, or R7F100GGN3CNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, industrial-grade temperature rating, CTSU2L support for up to 64-key mutual-capacitance touch panels, and SNOOZE mode sequencer enabling CPU-free low-power sensor polling.
Technical Context
The R7F100GGN3CNP#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). Its power management includes HALT, STOP, and SNOOZE modes, with STOP mode wakeup in under 4 µs and SNOOZE sequencer executing up to 32 configurable commands without CPU involvement.
Peripheral integration includes a 10-channel A/D converter (8-/10-/12-bit selectable), dual 8-bit D/A outputs, two comparators with internal/external reference selection, and Logic & Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals - all coordinated via the Data Transfer Controller (DTC) supporting block, repeat, and chain transfer modes.

FAQ
What is the maximum operating frequency and instruction execution speed of the R7F100GGN3CNP#AA0?
The R7F100GGN3CNP#AA0 features an RL78 CPU core with configurable clock sources: high-speed on-chip oscillator up to 32 MHz (minimum instruction time 0.03125 µs), middle-speed up to 4 MHz, and low-speed 32.768 kHz (30.5 µs min instruction time). The core supports 3-stage pipeline execution and multiply/divide instructions, enabling deterministic real-time response in industrial control loops.
Does the R7F100GGN3CNP#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGN3CNP#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix, up to 64 keys) methods. It operates across the full 1.8–5.5 V supply range and includes built-in noise suppression algorithms - enabling robust touch interfaces without external RC networks or shield layers.
What low-power modes does the R7F100GGN3CNP#AA0 support, and what is the lowest achievable current consumption?
The R7F100GGN3CNP#AA0 supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, it draws just 210 nA (typical) - verified across -40 to +105°C. SNOOZE mode enables CPU-free periodic operations (e.g., ADC sampling, GPIO toggling) using the sequencer, further reducing average system current in sensor polling applications.
Can the R7F100GGN3CNP#AA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GGN3CNP#AA0 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from program memory while data flash is rewritten - essential for field firmware updates, secure parameter storage, and runtime calibration data logging without system interruption.
What is the pin-compatible upgrade path from the R7F100GGN3CNP#AA0 within the RL78/G23 family?
The R7F100GGN3CNP#AA0 is pin-compatible with other 48-pin RL78/G23 variants in the same HWQFN package, including R7F100GGL3CNP#AA0 (384 KB flash), R7F100GLN3CNP#AA0 (512 KB flash), and R7F100GJN3CNP#AA0 (256 KB flash).
