The R7F100GGN3CFB#AA0: The RL78/G23 core runs at 32 MHz, with 768 KB of on-chip flash and 48 KB of SRAM — enough headroom for a full RTOS stack, a TCP/IP or CANopen library, and the application payload without external memory. An integrated 8 KB EEPROM array holds calibration constants and configuration data that survive power loss, eliminating a separate serial EEPROM from the BOM.
It integrates 768 KB of flash program memory, 48 KB of SRAM, and 8 KB of dedicated EEPROM — all on-chip, no external memory components required for typical embedded control applications.
The operating ambient temperature range is -40°C to +105°C, covering industrial and extended-temperature environments such as automotive under-hood or outdoor telecom cabinets.
The part is certified ROHS3 compliant. Standard Renesas documentation includes the datasheet, application notes, and PCN notifications — all available through the manufacturer portal.
