Product details
Overview
R7F100GLG3CFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB code flash, 48-KB RAM RL78/G23 16-bit microcontroller operating at 1.6–5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, and integrated capacitive touch sensing for industrial HMI applications.
For engineers reviewing the R7F100GLG3CFB#AA0 datasheet, R7F100GLG3CFB#AA0 pinout, R7F100GLG3CFB#AA0 application, or R7F100GLG3CFB#AA0 equivalent, key selection criteria include ultra-low-power STOP/SNOOZE modes, 16-bit TAU timers with RTC support, 12-bit ADC (26 channels), dual 8-bit DACs, and hardware-based CTSU2L capacitive sensing up to 64 keys in mutual mode.
Technical Context
The R7F100GLG3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) that executes 32 configurable commands without CPU wake-up, enabling autonomous sensor polling and low-power event sequencing.
Peripheral integration includes Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and dual serial interface types: up to 10 I²C/Simplified I²C channels and 6 UART/UARTA/LIN channels - all mapped across its 64-pin LFQFP package with 0.50-mm pitch.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL3CFB#AA0 | Same 64-pin LFQFP package and 512-KB flash, but 32-KB RAM (vs. 48 KB); no CTSU2L capacitive sensing unit. | Targeted at cost-sensitive control-only applications without touch UI; lacks hardware touch engine and associated analog front-end. | Select when RAM demand is ≤32 KB and capacitive sensing is unnecessary - reduces BOM cost while retaining identical pinout and peripheral set except CTSU. |
