The USAR GeniPS2TMUR3HCGNP­001 is a single IC that converts
PS/2 keyboard and mouse data to
USB.

The USAR GeniPS2TMis ideal for
applications, such as system
legacy support, where a seamless
connection of standard PS/2
devices, such as mouse or
keyboard to USB is needed.

The USAR GeniPS2TMsupports
boot mode of the USB 1.1
specification. The keyboard and
mouse will therefore function at
start-up, before the operating
system loads.

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 USAR 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 USAR 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

• Supports boot-mode of USB 1.1
specification - both keyboard and
mouse function at start-up

• Provides two PS/2 ports

• PS/2 ports support MouseWheel
functionality

USB Functionality

The USAR GeniPS2TMis a full­speed 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 USAR GeniPS2TMhandles 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.

PS/2 Ports

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.
