Product details
Overview
R7F100GEG2DNP#AA0 from Renesas is a 40-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and CSI for embedded control in battery-powered consumer devices.
For engineers reviewing the R7F100GEG2DNP#AA0 datasheet, R7F100GEG2DNP#AA0 pinout, R7F100GEG2DNP#AA0 application, or R7F100GEG2DNP#AA0 equivalent, key selection considerations include its 40-pin HWQFN-0.5mm package, -40°C to +85°C consumer-grade temperature range, 128 KB flash/16 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F100GEG2DNP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured operations-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic low-power sensor monitoring.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix) configurations under 1.8–5.5 V operation.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R7F100GEG2DNP#AA0?
The R7F100GEG2DNP#AA0 features a high-speed on-chip oscillator selectable up to 32 MHz with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = –20°C to +85°C. This eliminates the need for an external crystal in cost-sensitive consumer applications while maintaining timing integrity for UART and USB communications.
Does R7F100GEG2DNP#AA0 support capacitive touch sensing, and what configurations are available?
Yes, R7F100GEG2DNP#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 from 1.8–5.5 V and includes automatic drift compensation-enabling robust touch performance behind plastic, glass, or painted overlays without external components.
What low-power modes does R7F100GEG2DNP#AA0 support, and how does SNOOZE mode differ from STOP mode?
R7F100GEG2DNP#AA0 supports HALT, STOP, and SNOOZE modes. Unlike STOP mode-which halts CPU, flash, and RAM-SNOOZE mode keeps the CTSU2L, RTC, and SMS active while disabling the CPU and flash. The SMS autonomously executes up to 32 preloaded commands (e.g., ADC sampling, comparison, register update), enabling event-driven wake-up without CPU intervention.
Can R7F100GEG2DNP#AA0 perform background data flash writes while executing application code from program flash?
Yes, R7F100GEG2DNP#AA0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory while data flash is being rewritten-enabling seamless firmware parameter updates, calibration storage, or data logging without interrupting real-time control tasks.
What is the pin compatibility status of R7F100GEG2DNP#AA0 with other RL78/G23 variants in the 40-pin HWQFN package?
R7F100GEG2DNP#AA0 shares identical pinout, electrical characteristics, and peripheral mapping with all other 40-pin HWQFN RL78/G23 variants (e.g., R7F100GEF2DNP#AA0, R7F100GEH2DNP#AA0). Memory size differences (96–192 KB flash) do not affect pin functionality-allowing drop-in replacement within the same package family for design scalability.
