Description
The USAR HulaCoder
TM
UR7HCDMP is an easy-to-use
single-chip encoder that interfaces
an innovative sensor developed by
Fujitsu. Together they make the
USAR HulaPoint
TM
. 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
USAR HulaCoder
TM
implements all
commands from and to the 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. Power in the
serial mode, as in any standard
mouse, can be drawn from the
RS232 lines of the host system.
Custom versions are available to
suit a wide range of pointing
device applications.
