BU9206

Multimedia ICs PS / 2 Mouse Controller BU9206 The BU9206 is a PS / 2 mouse communication controller for PCs. This processor shapes waveforms and counts signals from the mouse rotary encoder as the mouse is moved, to provide two-way communication between mouse and PC system. Applications PC mouse Features 1) For PS / 2 mouse. 2) Compatible with a wide range of input signals, because it automatically sets the input threshold levels for the X and Y direction, corresponding to the output level of the rotary encoder inside the mouse. 3) CMOS process enables low current consumption.
