Serial connectivity includes CSI, I²C, LINbus, SPI, and UART/USART, so the part can talk to common peripherals (temperature sensors, motor drivers, display modules) without glue logic. ## Peer comparison — R7F100GFK2DFP#AA0 The closest sibling is the R7F100GFK2DFP#AA0, which shares the same 32 MHz RL78 core, 384 KB flash, 32 KB RAM, 37 I/O, and 44-LQFP package. The wider-temperature part is the one to specify if the board sees sustained heat near the 85 °C boundary.","metaTitle":"R7F100GFK3CFP#AA0 Renesas RL78/G23 MCU, 32 MHz, 384 KB Flash","metaDescription":"R7F100GFK3CFP#AA0 Renesas RL78/G23 16-bit MCU, 32 MHz, 384 KB Flash, 32 KB RAM, 8 KB EEPROM, 44-LQFP.
