R5F1076CGSP#X0

R5F1076CGSP#X0 is a RL78/I1A group microcontroller that output high-resolution PWM for fine dimming and toning of LED lighting. RL78/I1A microcontroller realize 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. 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, home appliance, lighting, motor control, power supply.
