Quad UART with 256 Byte TX/RX FIFO, 80-pin TQFP - 119pcs Bundle

• 256 Byte Tx/Rx Deep FIFOs
• Dedicated 2 Control Pins for RS422 and RS485 Bus Auto Control
• Data Rate up to 5.3Mbps
• Global Interrupt and Interrupt Vector Processing
• H/W and S/W Flow Control (Auto-RTS/CTS and Xon/Xoff)

SB16C1054 is a Quad-UART (Universal Asynchronous Receiver and Transmitter) with 256-byte FIFOs, automatic hardware/software flow control, and can transmit and receive the data up to 5.3 Mbps. The 256-byte FIFOs reduce CPU overhead, allowing higher data rate and data throughput. In addition to the increased FIFO size and data rate, SB16C1054 also provides the enhanced features. It has the registers for reducing interrupt signal control logic and storing threshold levels of receive FIFO to start/stop transmission during hardware and software flow control.
