Provides communications software and controllers for embedded applications, with an emphasis on Internet connectivity. Its powerful SX Series communications controller chips execute real-time Virtual PeripheralTM software modules that implement general-purpose, communications, networking and Internet connectivity functions. These modules are programmed into the high-speed on-chip flash memory of an SX Series chip to create the configuration required for the application. This "software system-on-a-chip" design strategy eliminates the silicon development time and cost associated with traditional design approaches, providing faster time to market, greater flexibility and reconfigurability.

Old information:
Designs and produces Human Input Device (HID) electronics and System Management products. HID products include pre-programmed IC's for keyboards, mice, touch screens, etc., as well as complete embedded mouse modules for OEM integration. System management products include ACPI-compliant embedded controllers with integrated keyboard and other HID functionality, including USARs ACPITrollerTM series. Geared chiefly to the portable and hand-held markets, USAR holds patents on several low-power implementation methods, providing ICs with the lowest power consumption available.
