UR7HCDMP

The HulaCoder™ UR7HCDMP is an easy-to-use single-chip encoder that interfaces an innovative sensor d eveloped by Fujitsu. Together they make the HulaPoint™. Equipped with an advanced motion algorithm, the UR7HCDMP offers low power consumption in a small footprint pac kage. The device can be linked through either the serial or PS/2- type mouse port of the host system.

The UR7HCDMP is compatible with the IBM and Microsoft two-button and the Logitech three-button mouse  communication protocols. The UR7HCDMP will auto switch between the Serial and the PS/2 mouse communication protocol depending on the port to which the device is actually connected.

Communication through the serial port is half-duplex at a fixed speed of 1200 Baud. PS/2 communication is bidirectional at 10 Kbps. The HulaCoder™ UR7HCDMP implements all commands to and from the host system, as defined in the IBM PS/2 mouse communication protocol.

The UR7HCDMP is a CMOS device operating at 4 MHz. The low power consumption of the IC makes it suitable for battery operated systems. In serial mode, like any standard serial mouse, the IC can draw power from the RS232 lines of the host system.
