The standard for general-purpose microcontroller with low power, high function, and abundant lineup
The RL78/G13 microcontrollers balance the industry's lowest level of consumption current (CPU: 66 μA/MHz, standby (STOP): 230 nA) and a high performance of 43.2 DMIPS (32 MHz). They have an on-chip oscillator, data flash, A/D converter, and more. Built-in safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). These microcontrollers can be used in a wide variety of applications from home and consumer appliances to industrial equipment.
