UR6HCPCS

The UR6HCPCS has the following features including PC Keyboard Emulation Port;Full-duplex Serial interface (RS232);Strobed Parallel Output Port;Pass-Through or ASCII TranslationMode;Jumper selectable baud rate;Auto repeat or single action mode;Single chip solution;HCMOS Technology;40-pin DIP, or 44-pin PLCC or 44-pin;QFP packages.

The UR6HCPCS is an easy-to-use single chip Protocol Interpreter that can link an AT/PS/2-compatible User Input Device (UID), such as a keyboard,mouse, bar-code reader, etc., to any host system equipped with a serial or parallel port. The UR6HCPCS emulates all the functions of the 8042 keyboard controller which typically resides on the AT/PS/2 motherboard. In addition, the Protocol Interpreter implements all levels of the keyboard BIOS protocol that handles two-way communication with the keyboard, performs error detection and elimination, and can translate all scan code information into an ASCII format understandable to application programs.The UR6HCPCS also supports a set of commands from the host system that can be used to control communication and functional characteristics of the UID. In a single chip, the UR6HCPCS offers the input device functionality previously achieved only by utilizing several ICs and BIOS modules set on a AT/PS/2 motherboard.

The UR6HCPCS is ideal for proprietary system designs needing to interface PC-compatible UIDs for aata entry purposes.Because the UR6HCPCS allows any system with a serial or parallel port to interface inexpensive, off-the-shelf UIDs without regard to that system's architecture or firmware,system designers and integrators can achieve maximum data entry performance without needing to spend the development time and costs associated with custom input device designs.At present there is not too much information about this model.If you are willing to find more  about USC1843, please pay attention to our web! We will promptly update the relevant information.As the UR6HCPCS implements all levels of input device protocol, no complicated software drivers are needed-translating in further savings for the system developer.The UR6HCPCS is also highly suitable for use in systems where multiple, concurrently operable UIDs are needed, such as Point of Sales Terminals, multi-user systems, industrial control systems, etc.
