Compact, low power, high function general-purpose microcontrollers ideal for sub-microcontrollers
RL78/G12 microcontrollers balance the industry's lowest level of consumption current (CPU: 63 μA/MHz, standby (STOP): 230 nA) and a high performance of 32.4 DMIPS (24 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). With a 20 to 30-pin compact package lineup, these microcontrollers are perfect for sub-microcontrollers of small appliances and consumer and industrial equipment.
