Product details
Overview
R7F100GGL2DNP#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 at 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual ADC resolution (8/10/12-bit) for battery-powered consumer HMI applications.
For engineers reviewing the R7F100GGL2DNP#AA0 datasheet, R7F100GGL2DNP#AA0 pinout, R7F100GGL2DNP#AA0 application, or R7F100GGL2DNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN footprint, -40°C to +85°C consumer-grade temperature range, SNOOZE mode sequencer for ultra-low-power sensor polling, and hardware-accelerated CTSU2L capacitive sensing unit.
Technical Context
The R7F100GGL2DNP#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 preconfigured processes-including ADC sampling, comparator comparison, and timer-triggered wakeups-without CPU, RAM, or flash activation.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 2-channel 8-bit DAC with real-time output, and flexible serial interfaces: up to 6 UARTA channels (LIN-capable), 10 I²C/Simplified I²C channels, and 8 CSI/SPI channels-all configurable via peripheral I/O redirection register (PIOR).

The R7F100GGL2DNP#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs; accuracy is ±1.0% over -20°C to +85°C ambient and 1.8–5.5 V supply.
Does the R7F100GGL2DNP#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GGL2DNP#AA0 integrates the CTSU2L capacitive 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 at VDD = 1.8–5.5 V and includes hardware noise cancellation, eliminating need for external touch controller ICs in the R7F100GGL2DNP#AA0 design.
How many serial communication interfaces does the R7F100GGL2DNP#AA0 provide, and which protocols are supported?
The R7F100GGL2DNP#AA0 provides up to 6 UARTA channels (including LIN-bus support), up to 10 I²C/Simplified I²C channels, and up to 8 CSI/SPI channels.
