Overview
R7F100GEG2DNP#HA0 from Renesas is a 40-pin RL78/G23 16-bit microcontroller with 96 KB code flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V, featuring capacitive touch sensing, 10-bit ADC (26 channels), and ultra-low-power STOP mode (210 nA). It targets battery-powered consumer HMI applications such as smart remote controls and portable sensor interfaces.
For engineers reviewing the R7F100GEG2DNP#HA0 datasheet, R7F100GEG2DNP#HA0 pinout, R7F100GEG2DNP#HA0 application, or R7F100GEG2DNP#HA0 equivalent, key selection criteria include its HWQFN-40 package, 210-nA data retention current, integrated CTSU2L capacitive sensing unit supporting up to 64 keys in mutual-capacitance mode, and dual UART/LIN support for low-power wireless peripheral control.
Technical Context
The R7F100GEG2DNP#HA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes a SNOOZE mode sequencer enabling autonomous low-power periodic wake-up without CPU involvement. Its power management integrates POR, dual LVDs, and HALT/STOP/SNOOZE modes.
Peripheral integration includes a 21-command SNOOZE sequencer, ELCL for event-driven logic routing between peripherals, and a CTSU2L unit configurable for self- or mutual-capacitance operation-enabling touch buttons, sliders, and proximity detection with hardware-accelerated noise immunity.
