Product details
Overview
R7F100GGN2DNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 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), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-power (32.768 kHz) modes for battery-powered consumer HMI applications.
For engineers reviewing the R7F100GGN2DNP#AA0 datasheet, R7F100GGN2DNP#AA0 pinout, R7F100GGN2DNP#AA0 application, or R7F100GGN2DNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, consumer-grade temperature range (−40 to +85°C), 256 KB flash/24 KB RAM configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F100GGN2DNP#AA0 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 dual-clock system integrates high-speed on-chip oscillator (±1.0% accuracy at 32 MHz), middle-speed oscillator, and low-speed 32.768 kHz oscillator with adjustability - enabling precise RTC operation and seamless clock domain switching.
Peripheral integration includes 16-bit Timer Array Unit (TAU) with up to 16 channels, 8–26-channel 8/10/12-bit ADC with internal 1.48 V reference and temperature sensor, 2-channel 8-bit DAC, 2-channel comparator with selectable internal/external reference, and Logic & Event Link Controller (ELCL) for hardware-triggered peripheral chaining without CPU intervention.

Yes, the R7F100GGN2DNP#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys). It operates within VDD = 1.8–5.5 V and includes built-in noise cancellation, making it suitable for touch sliders, buttons, and proximity detection in consumer electronics without external components.
How does the SNOOZE mode sequencer (SMS) in the R7F100GGN2DNP#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GGN2DNP#AA0 executes up to 32 predefined operations - including ADC conversions, CTSU2L scans, register comparisons, and peripheral triggers - without waking the CPU, flash, or RAM. This reduces active current to ~210 nA during idle periods, extending battery life significantly in intermittent-sensing applications like thermostats and remotes.

The R7F100GGN2DNP#AA0 supports UARTA (with LIN-bus protocol compliance), simplified SPI (CSI), and I²C/Simplified I²C interfaces. UARTA includes dedicated LIN transceiver support per ISO 17987, enabling direct connection to automotive and industrial LIN networks without external transceivers - verified in the RL78/G23 datasheet Section 1.1.
Is the R7F100GGN2DNP#AA0 pin-compatible with other RL78/G23 variants in the same 48-pin HWQFN package?
Yes, all RL78/G23 devices in the 48-pin HWQFN package - including R7F100GGN2DNP#AA0, R7F100GGL2DNP#AA0, and R7F100GGJ2DNP#AA0 - share identical pinouts, electrical characteristics, and package dimensions.
