BU97530KVT is a 1/5, 1/4, 1/3duty or Static general-purpose LCD driver that can be used for consumer / battery operated products and can drive up to 445 LCD Segments. It can control up to 9 general-purpose outputs / PWM output ports for LED backlighting and LED button illumination realizing less flicker by various frequency setting function. It can also support a key scan function that detects a maximum of 30 key inputs to reduce PCB wiring and to minimize microcontroller size and cost. It can support LCD contrast adjustment by its EVR function and TTL compatible input interface is also available, these are well-suited for wide-voltage range of MCUs.
