Product details
Overview
R7F100GFN2DFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UART, I²C, and SPI - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GFN2DFP#HA0 datasheet, R7F100GFN2DFP#HA0 pinout, R7F100GFN2DFP#HA0 application, or R7F100GFN2DFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C consumer-grade temperature range, 256 KB flash/24 KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking without CPU wake-up.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential low-power operations using 21 command types, enabling autonomous peripheral sequencing without CPU, flash, or RAM activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-level signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a Capacitive Touch Sensing Unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix, 64 keys) configurations under VDD = 1.8–5.5 V.
