32 MHz RL78 core with 256 KB flash — memory headroom for sensor fusion and HMI
The R7F100GBJ2DFP#BA0 is a 16-bit RL78/G23 microcontroller from Renesas, clocked at 32 MHz. It carries 256 KB of program flash, 24 KB of SRAM, and 8 KB of data EEPROM on-chip — enough headroom for a sensor-fusion stack with a capacitive-touch UI layer without external memory. The 32-LQFP package (7x7 mm) with 27 I/O keeps the board footprint compact, suiting it for handheld instruments or panel-mount controllers where every square millimeter counts.
