Product details
Overview
R7F100GPL2DFA#BA0 from Renesas is a 100-pin, 5.5-V tolerant RL78/G23 16-bit microcontroller with 512 KB code flash, 48 KB RAM, and integrated capacitive touch sensing (CTSU2L), designed for ultra-low-power industrial control and human-machine interface applications operating from -40°C to +85°C.
For engineers reviewing the R7F100GPL2DFA#BA0 datasheet, R7F100GPL2DFA#BA0 pinout, R7F100GPL2DFA#BA0 application, or R7F100GPL2DFA#BA0 equivalent, this page delivers verified electrical specs, validated package mapping (LFQFP-100, 0.50-mm pitch), confirmed SNOOZE mode sequencer operation, and real-world use cases in battery-powered HMI and sensor-aggregation nodes.
Technical Context
The R7F100GPL2DFA#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), and integrates a SNOOZE mode sequencer (SMS) that executes up to 32 low-power processes without CPU, flash, or RAM activation.
It features dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy at 32 MHz, VDD = 1.8–5.5 V) and subsystem clock (32.768 kHz), enabling precise RTC operation and fast wake-up from STOP mode with HALT/STOP/SNOOZE power states.
