Abstract: A peripheral device comprising a computer readable media and an interface circuit. The computer readable media may be configured to store instructions for operating the peripheral device. The interface circuit may be configured to communicate the instructions to an operating system of a computer in response to connection of the peripheral device to the computer.

Abstract: A microcontroller including a system bus; a microprocessor coupled to the system bus and configured to transfer data and control signals over the system bus; a memory device coupled to the microprocessor and mapped to the system bus and configured to store microprogram instructions for execution by the microprocessor; a controller coupled to the system bus and configured to transfer data and control signals to the microprocessor over the system bus; a host interface coupled to the system bus and configured to interface to a host computer and receive the data and the control signals over the system bus from the microprocessor; and an I/O interface coupled to the system bus and configured to interface to at least one I/O device and receive the data and the control signals over the system bus from the microprocessor.
