Overview
R7F100GMG3CFA#HA0 from Renesas is an RL78/G23 80-pin industrial-grade 16-bit MCU 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), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports STOP/SNOOZE modes for battery-powered sensor nodes and industrial HMI control.
For engineers reviewing the R7F100GMG3CFA#HA0 datasheet, R7F100GMG3CFA#HA0 pinout, R7F100GMG3CFA#HA0 application, or R7F100GMG3CFA#HA0 equivalent, key selection criteria include its LQFP-80 package with 0.65-mm pitch, -40 to +105°C industrial temperature rating, CTSU2L support for up to 64 keys in mutual-capacitance mode, and SNOOZE mode sequencer enabling CPU-free periodic sensing.
Technical Context
The R7F100GMG3CFA#HA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 processes using 21 command types without CPU, flash, or RAM activation-ideal for low-duty-cycle sensor polling.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain capability. The CTSU2L unit operates at VDD = 1.8–5.5 V and supports both self- and mutual-capacitance methods.
