GeniPS2TM UR3HCGNP-001 IC Converts PS/2 Data to USB
HID & SYSTEM MANAGEMENT PRODUCTS, PROTOCOL INTERPRETER FAMILY DESCRIPTION The GeniPS2TM UR3HCGNP-001 is a single IC that converts PS/2 keyboard and mouse data to USB. The GeniPS2TM is 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 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 GeniPS2TM supports remote wake-up function via either mouse or keyboard, if the BIOS of the host machine is configured in this manner. In addition, the GeniPS2TM supports a multitude of languages, including Korean and Japanese. FEATURES * * * * Interfaces PS/2 devices to USB Devices are hot-pluggable Provides two PS/2 ports PS/2 ports support MouseWheel functionality * 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

The PS/2 interface supports legacy Human Input Devices (HID)-class specification and uses two interrupt endpoints for the PS/2 devices. The GeniPS2TM 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.

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.
