Overview
R7F100GLN2DFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB code flash, 48-KB RAM RL78/G23 16-bit MCU operating from 1.6 to 5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, and integrated capacitive touch sensing (CTSU2L) for human-machine interface applications in industrial temperature range (−40 to +85°C).
For engineers reviewing the R7F100GLN2DFB#AA0 datasheet, R7F100GLN2DFB#AA0 pinout, R7F100GLN2DFB#AA0 application, or R7F100GLN2DFB#AA0 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral integration (UARTA ×6, IICA ×4, TAU ×16), and real-world use context for low-power embedded control design.
Technical Context
The R7F100GLN2DFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates SNOOZE mode sequencer (SMS) supporting 32 sequential low-power operations without CPU wake-up.
Its power management includes HALT/STOP/SNOOZE modes, dual voltage detectors (LVD0/LVD1), POR, and on-chip oscillators (32 MHz ±1.0% high-speed, 32.768 kHz low-speed). Peripheral interconnect is enabled via Event Link Controller (ELCL), allowing event-driven signal routing between timers, ADC, UART, and CTSU2L without software intervention.
