Product details
Overview
R7F100GPG2DFA#BA0 from Renesas is an RL78/G23 16-bit microcontroller with 100-pin LFQFP package, 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V at -40 to +85°C. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual 16-bit timer arrays for motor control and sensor interfacing in battery-powered industrial HMI systems.
For engineers reviewing the R7F100GPG2DFA#BA0 datasheet, R7F100GPG2DFA#BA0 pinout, R7F100GPG2DFA#BA0 application, or R7F100GPG2DFA#BA0 equivalent, key selection criteria include its 100-pin LFQFP footprint, 192 KB flash/20 KB RAM memory configuration, CTSU2L-based touch interface support, SNOOZE mode sequencer for low-power event processing, and UARTA/IICA/SAU peripheral set for industrial connectivity.
Technical Context
The R7F100GPG2DFA#BA0 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). Its SNOOZE mode sequencer executes up to 32 configurable commands without CPU wake-up, enabling autonomous sensor polling and threshold comparison.
Peripheral integration includes a 26-channel 12-bit A/D converter with internal 1.48 V reference and temperature sensor, dual 8-bit D/A outputs (0–VDD), two comparators with selectable internal/external references, and ELCL logic for event-driven peripheral chaining-critical for deterministic real-time response in embedded control loops.

The SNOOZE mode sequencer in the R7F100GPG2DFA#BA0 executes up to 32 pre-programmed commands-including ADC reads, value comparisons, and GPIO toggles-without waking the CPU, flash, or RAM. This enables autonomous periodic sensor polling and conditional actions at microamp-level current draw, reducing average system power by >90% compared to CPU-driven polling in applications like battery-powered environmental monitors using the R7F100GPG2DFA#BA0.
What serial communication interfaces are integrated into the R7F100GPG2DFA#BA0, and how many channels does each support?
The R7F100GPG2DFA#BA0 integrates three serial interface families: up to 10 IICA (I²C-compatible) channels, up to 6 UARTA channels (with LIN-bus support), and up to 8 CSI (SPI-compatible) channels-all configurable via peripheral I/O redirection registers. These interfaces share pins dynamically, allowing flexible allocation (e.g., 4 IICA + 2 UARTA + 2 CSI) without hardware changes, maximizing peripheral utilization in space-constrained designs using the R7F100GPG2DFA#BA0.
Is the R7F100GPG2DFA#BA0 pin-compatible with other RL78/G23 variants in the same 100-pin LFQFP package?
Yes, all RL78/G23 devices in the 100-pin LFQFP package-including R7F100GPG2DFA#BA0, R7F100GPJ2DFA#BA0, and R7F100GPL2DFA#BA0-share identical pinouts, electrical characteristics, and peripheral mappings.
