Semtech Corporation UR5HCFJ8
The UR5HCFJ8 provides two bi-directional channels for communication with a BIOScompatible system as well as any optional keyboard-compatible devices, such as a 101/102 desktop keyboard. The keyboard encoder handles the scanning, debounce, and encoding of 82 keys organized on an 8x16 matrix and supports embedded numeric keypad functions as well as alternate scan codes for specific keys, so that a keyboard with only 82 keys is able to emulate the functionality of a 101/102 keyboard. In addition to the system’s keyboard communication port the UR5HCFJ8 provides a fully functional keyboard input port that can be used by a standard 82/101/102 keyboard or another 8042-compatible device, such as an external numeric keypad, an OCR, or a bar-code reader.
