SC16C754B 5 V, 3.3 V And 2.5 V Quad UART, 5 Mbit/s (max.) With 64-byte FIFOs

The SC16C754B is a quad Universal Asynchronous Receiver/Transmitter (UART) with 64-byte FIFOs Automatic hardware/software flow control, and data rates up to 5 Mbit/s (3.3 V and 5 V). The SC16C754B offers enhanced features. It has a transmission control Register (TCR) that stores receiver FIFO threshold levels to start/stop transmission during hardware and software flow control. With the FIFO RDY Register the software gets the status of TXRDY/RXRDY for all four ports in one access. On-chip status Registers provide the user with error indications, operational status, and modem Interface control. System interrupts may be tailored to meet user requirements. An internal loop-back capability allows on-board diagnostics. The UART transmits data, sent to it over the peripheral 8-bit bus, on the TX signal and receives characters on the RX signal. Characters CAN be programmed to be 5, 6, 7, or 8 bits. The UART has a 64-byte receive FIFO and transmit FIFO and CAN be programmed to interrupt at different trigger levels. The UART generates its own desired baud rate based upon a programmable divisor and its input Clock It CAN transmit even, odd, or no parity and 1, 1.5, or 2 stop bits. The receiver CAN detect break, idle, or framing errors, FIFO overflow, and parity errors. The transmitter CAN detect FIFO underflow. The UART also contains a software Interface for modem control operations, and has software flow control and hardware flow control capabilities. The SC16C754B is available in plastic LQFP64, LQFP80 and PLCC68 packages.
