Product details
Overview
R7F100GPG2DFB#BA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for real-time control in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GPG2DFB#BA0 datasheet, R7F100GPG2DFB#BA0 pinout, R7F100GPG2DFB#BA0 application, or R7F100GPG2DFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature rating, 256 KB/24 KB memory configuration, CTSU2L capacitive sensing capability, and support for UARTA, IICA, SAU, and RTC peripherals.
Technical Context
The R7F100GPG2DFB#BA0 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). It integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power peripheral sequencing without CPU wake-up, and an Event Link Controller (ELCL) for hardware-triggered inter-peripheral signal routing.
Its power architecture includes three on-chip oscillators (high-speed up to 32 MHz ±1.0%, middle-speed, and 32.768 kHz low-speed), POR/LVD reset circuitry, and HALT/STOP/SNOOZE low-power modes. The CTSU2L unit supports both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix) touch sensing under VDD = 1.8–5.5 V.
