XR82C684 Quad UART with Four Fully Independent Full-Duplex Asynchronous Communication Channels
The EXAR Quad Universal Asynchronous Receiver and Transmitter (QUART) is a data communications device that provides four fully independent full-duplex asynchronous communication channels in a single package. The QUART is designed for use in microprocessor based systems and may be used in a polled or interrupt-driven environment. The XR-82C684 device offers a single IC solution for various microprocessor families. The "88" and "68 modes" (for the 8800 and 68000 family of processors, respectively) can be selected by tying the SEL pin to VDD or VSS. The QUART is fabricated using advanced two layer metal, with a high performance density EPI/CMOS 1.8. process to provide high performance and low power consumption, and is packaged in a 44 pin PLCC and a 68 pin PLCC
