product specifications
Description
Features
The USAR GeniPS2TM UR3HCGNP-
001 is a single IC that converts
PS/2 keyboard and mouse data to
USB.
The USAR GeniPS2TM is 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 GeniPS2TM supports
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
GeniPS2TM auto-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 GeniPS2TM supports
remote wake-up function via either
mouse or keyboard, if the BIOS of
the host machine is configured in
this manner.
