HulaCoder™ UR7HCDMP
HulaPoint™ Ergonomic Mouse
PS/2 and RS232 Encoder
HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODER® FAMILY
PRELIMINARY
DESCRIPTION
The HulaCoder™ 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™ ergonomic mouse.
Equipped with an advanced motion
algorithm, the HulaCoder™ 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.
FEATURES
• Equipped with advanced motion-
control algorithm
• Low power consumption in a
3-volt to 6-volt operating range
• Effortless and accurate cursor
control with 10-degree movement
in every direction
• Compatible with IBM/Microsoft
two-button mice and Logitech
three-button mice
APPLICATIONS
• Works with innovative, proprietary
sensor technology developed by
Fujitsu Microelectronics
• Responds to feather-light touch
without resistance
• Available in a small 18-pin plastic
SOIC package
• Autoselects RS232 or PS/2
hardware interface
The HulaCoder™ 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™ is half-duplex at a
fixed speed of 1200 Baud. PS/2
communication is bidirectional at 10
Kbps. The HulaCoder™
implements all commands to and
from the host system, as defined in
the IBM PS/2 mouse communication
protocol.
The HulaCoder™ 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.
