Product details
Overview
R7F100GMK2DFA#AA0 from Renesas is an RL78/G23 80-pin, 384-KB code flash, 32-KB RAM ultra-low-power 16-bit MCU operating from 1.6 to 5.5 V, featuring 26-channel 12-bit ADC, capacitive touch sensing (CTSU2L), RTC, and SNOOZE mode sequencer - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GMK2DFA#AA0 datasheet, R7F100GMK2DFA#AA0 pinout, R7F100GMK2DFA#AA0 application, or R7F100GMK2DFA#AA0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, -40°C to +85°C consumer-grade temperature range, and integrated CTSU2L for self/mutual-capacitance touch up to 64 keys without CPU involvement.
Technical Context
The R7F100GMK2DFA#AA0 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 dedicated SNOOZE mode sequencer (SMS) that executes up to 32 low-power processes using 21 command types without waking the CPU, flash, or RAM.
It integrates dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy at 1–32 MHz), low-speed 32.768-kHz oscillator for RTC, and event link controller (ELCL) enabling hardware-level signal routing between peripherals - eliminating software overhead for inter-peripheral triggering.
