DESCRIPTION
The HulaCoder鈩?UR7HCDMP is an
easy-to-use single-chip encoder
that interfaces an innovative sensor
developed by Fujitsu. Together they
make the HulaPoint鈩? Equipped
with an advanced motion algorithm,
the UR7HCDMP offers low power
consumption in a small footprint
package. 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 device 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鈩?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.
