DESCRIPTION FEATURES

• System Legacy Support

The GeniPS2TMUR3HCGNP-001 is
a single IC that converts PS/2
keyboard and mouse data to USB.

The GeniPS2TMis ideal for system
legacy support, enabling seamless
connection of standard PS/2
devices (mice or keyboards) to
USB.

The IC offers two hot-pluggable
and hot-swappable PS/2 ports;
either port can accept a mouse
or a keyboard. In addition, the
GeniPS2TMauto-detects and
transparently supports mice with
MouseWheel functionality. Internal
and external mouse and keyboard
data are streamed and appear to
the system as if coming from a
single source.

The GeniPS2TMsupports remote
wake-up function via either mouse
or keyboard, if the BIOS of the host
machine is configured in this
manner.

In addition, the GeniPS2

TM

supports
a multitude of languages, including
Korean and Japanese.

• PS/2 ports are auto-selectable and
hot-swappable – the mouse or
keyboard can be used in either
port

• Works with standard Windows 98
keyboard and mouse drivers

• Easy to implement

• Few external components required

• Interfaces PS/2 devices to USB

• Devices are hot-pluggable

• Provides two PS/2 ports

• PS/2 ports support MouseWheel
functionality

The GeniPS2TMis a full-speed
composite USB device that
interfaces PS/2.

The PS/2 interface supports legacy
Human Input Devices (HID)-class
specification and uses two interrupt
endpoints for the PS/2 devices.

The GeniPS2

TM

handles the merging
of all this data, and sends the data
to the system. Data can come from
either of the two PS/2 ports.
Internal and external mouse and
keyboard data are streamed and
appear to the system as if coming
from a single source.

The two PS/2 ports allow the user
to connect legacy PS/2 devices to
the USB host system. Standard
104-key keyboards and PS/2 mice,
with support for MouseWheel
functionality, can be hot-plugged at
either of the PS/2 ports and
immediately begin communicating
with the host.
