UR7HCPXZ-P440

The PixiPointTM Z UR7HCPXZ-P440 mouse encoder is a cost-effective, highfunctionality IC designed to interface the CTS 106, 108 and 109 sensors to the PS/2 port. Ideal for laptop/palmtop use, the low power PixiPointTM Z offers an advanced algorithm for enhanced motion control. The IC UR7HCPXZ-P440 also enables click, double-click, MouseWheel action and slow drag without the need for special drivers. The IC UR7HCPXZ-P440 provides an extra port for hot-plug connection of an external pointing device, including those with built-in Mousewheel. Both the embedded sensor and the external device can be operated concurrently.

The PixiPointTM Z UR7HCPXZ-P440 utilizes a special signal conditioning circuit (US and International patent pending) which enables a low cost, simple and real estate-saving implementation. Just a few low tolerance external components are needed. The IC implements typically consumes less than 3mA, making UR7HCPXZ-P440 suitable for use in battery-operated systems.

PS/2 communication is idirectional at 10 kbps. The IC UR7HCPXZ-P440, a MOS device operating at 4 MHz, s compatible with both the IBM nd Microsoft two-button and the ogitech three-button mouse rotocols. It implements all ommands from and to the ystem, s defined in the IBM PS/2 Mouse ommunication Protocol. Custom ersions of UR7HCPXZ-P440 are also available to suit a ange of applications.
