HulaCoder鈩?UR7HCDMP
HulaPoint鈩?Ergonomic Mouse
PS/2 and RS232 Encoder
HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODER廬 FAMILY
DESCRIPTION
The HulaCoder鈩?UR7HCDMP is an
easy-to-use single-chip encoder
that interfaces to an innovative
sensor developed by Fujitsu. The
IC and sensor together make the
HulaPoint鈩?ergonomic mouse.
Equipped with an advanced motion
algorithm, the HulaCoder鈩?offers
low power consumption in a small-
footprint package. The device
connects to either a serial or a PS/2
mouse port on the host system.
The HulaCoder鈩?is compatible with
the communication protocols for
IBM and Microsoft two-button mice
and Logitech three-button mice.
The IC automatically detects the
port type (serial or PS/2) and uses
the appropriate protocol for that port
type.
Serial communication by the
HulaCoder鈩?is half-duplex at a
fixed speed of 1200 Baud. PS/2
communication is bidirectional at 10
Kbps. The HulaCoder鈩?/div>
implements all commands to and
from the host system, as defined in
the IBM PS/2 mouse communication
protocol.
The HulaCoder鈩?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.
