16-bit MCU with balanced on-chip memory for sensor-fusion and control tasks
The Renesas RL78/G23 R7F100GGH2DFB#BA0 is a 16-bit microcontroller built around the RL78 core, clocked at 32 MHz. It carries 192 KB of flash program memory, 20 KB of RAM, and 8 KB of dedicated EEPROM — enough headroom for a modest application stack plus non-volatile parameter storage without external memory ICs.
Peripheral mix that reduces external component count
The ADC block offers 10 channels with selectable 8-, 10-, or 12-bit resolution, plus a 2-channel 8-bit DAC — enough to handle a multi-sensor analog front-end without a separate converter IC. The capacitive touch sensing unit supports HMI interfaces like membrane buttons or proximity sliders directly. Serial connectivity includes CSI, I²C, LINbus, SPI, and UART/USART, so the MCU can talk to common fieldbus transceivers, external ADCs, or display modules without glue logic. The 40 GPIOs in the 48-LQFP package leave room for parallel LCD buses or multiple sensor interrupts. On-chip peripherals also include LVD (low-voltage detect), POR (power-on reset), PWM, and a watchdog timer — these handle supply monitoring and system supervision without external supervisor ICs.
Active lifecycle and supply posture for BOM planning
The part is ROHS3 compliant, meeting current EU environmental requirements for global shipping.
