General description
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.
