Renesas Electronics RL78/G13 Series MCUs

Renesas Electronics RL78/G13 Series Microcontrollers (MCUs) are high-function general-purpose microcontrollers that consume low power and are available with an abundant lineup of various configurations. These MCUs balance the low level of consumption current (CPU: 66μA/MHz, standby (STOP): 230nA) and 43.2 DMIPS (32MHz) high performance. The RL78/G13 MCUs are capable of enabling IEC/UL 60730 safety standards for household appliances through built-in safety features. These microcontrollers can be used in a wide variety of applications, from home and consumer appliances to industrial equipment, healthcare, and security.
