It also integrates 8K x 8 of data EEPROM, which saves an external serial EEPROM on the board. The wide supply range from 1.8 V to 5.5 V lets it sit on a 3.3 V or 5 V rail without a regulator change, and the -40°C to 105°C operating temperature covers industrial environments like motor drives, outdoor telecom, and factory automation panels. Built-in peripherals include capacitive touch sensing, LVD, POR, PWM, and WDT — the touch engine is the standout, eliminating a separate touch controller IC for membrane buttons or sliders. Connectivity covers CSI, I²C, LINbus, SPI, and UART/USART, enough for sensor fusion and local control links. ## Capacitive touch — no external controller needed The capacitive touch peripheral is built into the RL78/G23 core, so a design with a few touch buttons or a slider can skip the dedicated touch MCU or capacitive-sense IC. That saves BOM cost and board area. The peripheral handles the electrode scanning and noise filtering internally; the firmware just reads the touch status registers. ## Package and footprint Housed in a 44-LQFP (10x10 mm) package with 37 general-purpose I/O pins. The surface-mount LQFP is standard for hand-assembly and reflow, and the 0.8 mm pitch is easy to route on a two-layer board. The supplier device package is 44-LQFP (10x10). ## Lifecycle and sourcing This part carries an Active lifecycle status per Renesas, so there is no last-time-buy risk for production ramps or long-running designs. ROHS3 compliant.","metaTitle":"Renesas R7F100GFF3CFP#AA0 RL78/G23 16-bit MCU, 32MHz","metaDescription":"Renesas R7F100GFF3CFP#AA0 RL78/G23 16-bit MCU: 32MHz core, 96KB Flash, 12K x 8 RAM, 8K x 8 EEPROM, capacitive touch, -40°C to 105°C.
