RL78 Family


RL78 is Renesas Electronics' new-generation microcontroller family combining advanced features from both the 78K and R8C families to deliver low power consumption and high performance.
RL78 is based upon a 16 bit CISC architecture with analogue rich functionality. The platform lineup will include general purpose, LCD and ASSPs including lighting and automotive microcontrollers.
RL78 is designed specifically for ultra low power applications enabling customers to build compact and energy-efficient systems at lower cost.
