Product details

Memory mix and what it means for firmware

96 KB Flash is enough for a moderate control loop with a communication stack (e.g., Modbus RTU over UART or a simple CANopen node). 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.

Frequently asked questions

How does R7F100GLF3CFA#AA0 compare to the RL78/G23 other memory variants?

Within the RL78/G23 family, the 96 KB Flash / 12 KB RAM / 8 KB EEPROM configuration sits between the 64 KB Flash entry-level parts and the 128 KB / 256 KB Flash higher-density options. The 54 I/O count and 64-LQFP package are shared with several mid-range siblings; the key difference is the memory budget for firmware and data.

Does R7F100GLF3CFA#AA0 support I2C communication?

Yes, the connectivity list includes I²C (along with CSI, LINbus, SPI, and UART/USART), so it can act as an I²C master or slave on a multi-drop sensor bus.
