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) I2C Bus interface.
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.(LCDT0, LCDT1)
8)Power aupply voltages: 3.3V to 5.0V
