产品信息

The SC16C654DBIB64 is a Quad Universal Asynchronous Receiver and Transmitter (QUART) used for serial data communICations. Its principal function is to convert parallel data into serial data and vice versa. The UART can handle serial data rates up to 5Mbps. It comes with an Intel or Motorola interface. The programming of control registers enables the added features of the QUART. Some of these added features are the 64-byte receive and transmit FIFOs, automatic hardware or software flow control and infrared encoding/decoding. The selectable auto-flow control feature significantly reduces software overload and increases system efficiency while in FIFO mode by automatically controlling serial data flow using RTS output and CTS input signals. It also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals. On-board status registers provide the user with error indications, operational status and modem interface control.
