The 12 KB RAM handles a few hundred bytes of packet buffers plus real-time variables. The 8 KB EEPROM is useful for storing calibration constants or fault logs without wearing the Flash — no external serial EEPROM needed. ## Peripheral set for HMI and fieldbus Capacitive touch sensing is built in, so a membrane panel or touch slider connects directly without a dedicated touch controller. The CSI, I²C, SPI, and UART/USART interfaces cover most fieldbus and sensor links: LINbus for automotive subnets, I²C for local sensor buses, SPI for external ADC/DAC or display modules. The LVD (low-voltage detect) and POR (power-on reset) reduce external supervisor IC count. ## Sourcing and lifecycle Renesas lists this part as Active.","metaTitle":"R7F100GLF3CFA#AA0 RL78/G23 16-bit MCU, 32 MHz, 96 KB Flash","metaDescription":"R7F100GLF3CFA#AA0 RL78/G23 16-bit MCU from Renesas. 32 MHz core, 96 KB Flash, 12 KB RAM, 8 KB EEPROM, 54 I/O, -40°C to 105°C.
