Multimedia ICs Status display LCD driver for PCs with I2C Bus interface BU9910KV The BU9910KV is a status LCD driver with I2C Bus intetface. Various lighting mode can be controlled through I2C Bus. In addition, 20 direct drive inputs allow the application to drive 20 elements directly without I2C Bus, so that the system configuration can be kept simple. Applications • PCs Features • 1) I C Bus interface. 2 2) Drive up to 44 LCD cells. 4 common × 11 segment, 1 / 3 bias, 1 / 4 duty 3) Blink operation for eaeh cell. 4) Support four frame frequencies 256Hz, 128Hz, 64Hz, 32Hz (at fOSC = 32.768kHz) 5) 20 direct drive inputs, which allow the application to drive LCD directly without I2C control. 6) Minimum LCD drive time is guaranteed for direct in. 7) LCD device test ferminals.
