R5F107DEGSP#X0

RL78/I1A is a microcontroller that output high-resolution PWM for fine dimming and toning of led lighting. This microcontroller realizes PWM output of a minimum 0.98ns resolution using 64MHz 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. A low consumption current of 3.3mA during LED and power supply control and 0.23μA 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. This microcontroller can be used in LED lighting equipment and digital power supplies.
