RL78 is the family name for a range of 16-bit microcontrollers. These were the first new MCU to emerge from the new Renesas Electronics company after the merger of NEC Electronics and Renesas Technology. These Microcontrollers incorporate the core features of the NEC 78K0R (150 nm MF2 flash process) and many familiar peripherals from legacy Renesas R8C microcontrollers. The RL78 core variants include the S1, S2, and S3 type cores which evolved from the NEC 78K0R core. The basic S1 core support 74 instructions, the S2 core adds register banking and supports 75 instructions, while the S3 core adds an on-chip multiplier / divider / multiple-accumulate and supports 81 instructions.
The RL78 was developed to address extremely low power but highly integrated microcontroller applications, to this end the core offered a novel low power mode of operation called “snooze mode” where the ADC or serial interface can be programmed to meet specific conditions to wake the device from the extreme low power STOP mode of 0.52uA.

s developed by Renesas, as opposed to the H family and the MC family, launched by Hitachi and Mitsubishi respectively.
The RX family was launched in 2009 by Renesas Technology with the first product range designated the RX600 series and targeting applications such as metering, motor control, human–machine interfaces (HMI), networking, and industrial automation. Since 2009 this MCU family range has been enlarged with a smaller variant the RX200 series and also through enhanced performance versions.
Key to the high performance of the microcontroller is the CISC architecture with high performance integrated flash memory enabling the central processing unit (CPU) to operate at very high frequency, 100 MHz, without requiring wait-states for the memory accesses resulting in performance up to 1.65 DMIPS/MHz.
The RA MCU family
The RA, an acronym for Renesas Advanced, is the family name for a range of 32-bit
