概览

RL78/I1A microcontrollers realize PWM output of a minimum 0.98 ns resolution using 64 MHz timer operation and dithering function, supporting fine dimming and toning. Through cooperation between the PWM timer and comparator/external interrupt input, PFC control and protection functions can be realized by hardware. Low consumption current of 3.3 mA during LED and power supply control and 0.23 μA when waiting for UART (DALI) communication allows the power consumption of the system to be reduced. DALI/DMX512 lighting communication and Power Management Bus (PMBus) and System Management Bus (SMBus) power communication are supported. These microcontrollers can be used in LED lighting equipment and digital power supplies.
