Product details
Overview
R7F100GFL2DFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller featuring 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating at 1.6–5.5 V with ultra-low-power STOP mode (210 nA data retention) and integrated capacitive touch sensing for HMI applications in industrial control panels.
For engineers reviewing the R7F100GFL2DFP#HA0 datasheet, R7F100GFL2DFP#HA0 pinout, R7F100GFL2DFP#HA0 application, or R7F100GFL2DFP#HA0 equivalent, this page delivers verified electrical specs, validated peripheral mapping, real-world use cases in battery-powered sensing and motor control, and confirmed alternative options for design flexibility.
Technical Context
The R7F100GFL2DFP#HA0 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 a SNOOZE mode sequencer (SMS) enabling autonomous low-power sensor polling without CPU wake-up.
Peripheral integration includes up to 26-channel 12-bit ADC with internal 1.48 V reference and temperature sensor, dual 8-bit DAC outputs, two comparators with selectable internal/external reference, and a logic/event link controller (ELCL) for hardware-triggered signal routing between timers, UARTs, and I²C interfaces.
Key Specifications
