RL78/G23 16-bit MCU with 768 KB Flash and capacitive touch
The R7F100GGN3CNP#AA0: It integrates a capacitive touch sensing unit, LVD, POR, PWM, and WDT peripherals, plus a 10-channel A/D converter configurable to 8-, 10-, or 12-bit resolution and a 2-channel 8-bit D/A converter.
The 32 MHz clock rate on the RL78 core delivers a balance of processing throughput and low active current typical of the family.
768 KB Flash and 40 I/O — sizing the BOM fit
With 768 KB of Flash, this MCU targets applications that require moderate code space for communication stacks, touch firmware, and application logic without stepping up to a 32-bit part. The 40 I/O count in a 48-WFQFN package provides enough GPIO for parallel sensor inputs, display interfaces, or keypad matrices while keeping the footprint compact. The supply voltage is 1.8 V, which aligns with low-power battery-operated or 1.8 V logic rail designs.
Industrial temperature grade and capacitive touch
The integrated capacitive touch peripheral supports touch-button, slider, and wheel interfaces without an external touch controller, reducing BOM cost and PCB area for HMI designs in industrial panels or white goods.
This is a clean fit for new product introductions and ongoing production runs without supply discontinuity risk.
